Leopard-Gecko — Care & Reference Manual

LLM-refined manual (v2 pipeline, kimi, 2026-08-04; docs/MANUAL_V2_DESIGN.md). This manual assembles the verified fact blocks in Pet Data Station that mention leopard-gecko, organised along a pet owner's journey. Every quoted fact is reproduced verbatim from its cited first-hand source ([n] superscripts; see References, each tagged with a computed trust grade per docs/topic_grading_guide.md) and is independently checkable. Guide sections (checklists, red-flag box) are orientation prose in which every factual sentence carries its own [n]; derived-summary blocks from non-Open-Access sources keep their Paraphrased derived summary mark. Mis-sectioned, duplicate, off-topic and image-residue fragments were removed by the v2 builder (build-gate enforced).

Species Profile

The profile below records this species' taxonomy, natural origin and lifespan as documented in the cited reference.

Leopard gecko (Eublepharis macularius) — species profile (taxonomy, geographic range, habitat, physical description, behavior, wild diet, reproduction, lifespan)

Leopard geckoes can be found throughout Afghanistan, Iraq, Iran, Northwest India (Henkel 1995) and Pakistan (Hunziker 1994, de Vosjoli 1990). [1]

Dry and semi-dry desert regions (Henkel 1995) and arid grasslands (Hunziker 1994). [1]

Ground color is usually yellow with irregular black spots and a white ventrum. [1]

Leopard geckoes have a segmented tail which may be autotomized, and movable eyelids (Henkel 1995) with a vertical slit pupil (Hunziker 1994) unlike many geckoes. [1]

They also lack toe pads, having clawed toes instead (Hunziker 1994). [1]

Leopard geckoes are nocturnal, sheltering under rocks or in burrows in daylight (Henkel 1995, Hunziker 1994). [1]

During periods of activity, the gecko tends to be an inquisitive animal, and although a ground-dwelling species, the clawed toes of the leopard gecko allow them to climb rocks and branches where they can easily absorb heat ventrally (Hunziker 1994). [1]

As with many other reptiles, these lizards shed periodically. [1]

This species eats the sloughed skin (Henkel 1995). [1]

Leopard geckoes are very adaptable, and are known to eat scorpions, centipedes, spiders, and beetles in the wild (Hunziker 1994). [1]

In captivity, leopard gecko diets usually consist of crickets, mealworms, waxworms, pinkie or nestling mice, locusts, grasshoppers, and springtails (Hunziker 1994, Henkel 1995). [1]

Clutches almost universally consist of two eggs, although a healthy female may produce as many as six clutches per year (Hunziker 1994). [1]

The eggs measure approximately 28 x 15 mm, and hatch after 45-53 days at 28 degrees Celsius. [1]

Hatchlings are about 85 mm in length (Henkel 1995). [1]

No information was found on the status of this species in the wild. [1]

Life-Stage Care

Young, adult and senior care for this species, drawn from first-hand care pages and veterinary references.

Reptile — life stage (owner-practical care, Merck Veterinary Manual pet-owner)

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Offering a variety of foods at each feeding, particularly to younger reptiles, may reduce picky-eating problems. [2]

High-protein commercial diets can drive rapid growth but may cause serious long-term problems such as hyperuricemia. [2]

In captivity, this species has a life span of approximately 22 years (Henkel 1995). [1]

Is this pet right for you?

• A 20+ year commitment: in captivity, leopard geckos have a life span of approximately 22 years. [1]
• A nocturnal desert gecko: leopard geckos come from dry and semi-dry desert regions and arid grasslands, are nocturnal (sheltering under rocks or in burrows by day), and lack toe pads, having clawed toes instead. [1]
• Small and ground-dwelling: they are ground-dwelling, about 85 mm as hatchlings, with a yellow ground color and black spots, and a segmented tail that may be autotomized. [1]
• Insect-eaters, not fussy: in the wild they eat scorpions, centipedes, spiders and beetles, and in captivity diets are usually crickets, mealworms, waxworms, pinkie mice, locusts, grasshoppers and springtails. [1]
• Novice-friendly: leopard geckos breed readily in captivity and are often ideal for novice owners, needing less special broad-spectrum lighting than many reptiles. [3]
• Observe, don't over-handle: reptiles suit adults or older children who enjoy observing them rather than handling them. [2]

Daily & Weekly Care Checklist

Every day:

• Live insects only: leopard geckos are insectivores fed a variety of live insects (crickets, mealworms, superworms, silkworms, dubia roaches, hornworms). [4]
• Gut-load the feeders: because they get all nutrition from insects, gut-load feeder insects for 2–3 days before offering to raise their nutritional value. [4]
• Calcium supplementation: their insect diet needs regular calcium supplementation, and UVB (290–300 nm) supports vitamin D3 synthesis and calcium regulation. [3] [4]
• UVB and heat: provide broad-spectrum lighting (unfiltered sunlight best, artificial UVB as alternative) and a temperature gradient; basking lamps are the preferred heat/light source for lizards. [3] [2]
• Check the temperatures: keep at least two thermometers (cool and warm ends) and measure the temperature just above the substrate where the animal rests. [2]

Every week:

• Humidity for shedding: humid microclimates are critical for arid species like leopard geckos to reduce abnormal sheds; provide a damp hiding area. [3]
• Avoid dried insects: dried insects should be avoided as they tend to have a dehydrating effect; canned insects may be used if the gecko will eat them. [4]
• Keep it clean: a simpler substrate is easier to keep clean; newspaper is the preferred substrate for ill reptiles. [2]

Nutrition

The short version: leopard geckos are insectivores fed a variety of live, gut-loaded insects (2–3 days) with regular calcium supplementation; dried insects are avoided because they dehydrate. [4] [3]

The quotes below summarise this species' dietary requirements and nutrition-related disease risks, drawn from professional veterinary references.

Leopard gecko feeding — insectivore; varied live insects; gut-load 2-3 days; avoid dried insects

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Leopard geckos are insectivores and should be fed a variety of live insects including crickets, mealworms, superworms, silkworms, dubia roaches and hornworms. [4]

Because leopard geckos get all their nutrition from insects, feeder insects should be gut-loaded for 2-3 days before offering to raise their nutritional value. [4]

Dried insects should be avoided as they tend to have a dehydrating effect on reptiles; canned insects may be used if the gecko will eat them. [4]

Reptile nutrition — UVB-dependent vitamin D3 synthesis and calcium regulation

All lines in this block are paraphrased derived summaries — non-Open-Access source.

For most active (diurnal) lizards and turtles, UVB light is needed to make vitamin D3, which controls calcium balance. [5]

Reptile nutrition — calcium:phosphorus ratio and UVB-dependent D3

All lines in this block are paraphrased derived summaries — non-Open-Access source.

X-rays often show mineralized or radiolucent tophi in organs and joints (as seen in gout). [6]

Primary visceral gout is urate crystal deposition in organs from chronic hyperuricemia, usually excess dietary protein. [6]

Correcting the diet treats primary visceral gout. [6]

Among reptile metabolic bone diseases, nutritional secondary hyperparathyroidism is the most common. [6]

It stems from poor diet (low calcium-to-phosphorus ratio, vitamin D3 lack) or poor husbandry (no UVB, insufficient heat). [6]

Affected animals are usually fast-growing herbivorous or insectivorous lizards and turtles. [6]

Late-stage findings include hyperphosphatemia and low total and ionized calcium. [6]

Critical cases need fluid therapy, nutritional support, parenteral calcium if hypocalcemic, and phosphate binders if hyperphosphatemic. [6]

Correcting diet and husbandry is the mainstay of successful treatment, with a favorable prognosis especially if the animal is still eating. [6]

[Paraphrased derived summary — non-Open-Access source.] UVB light (290–300 nm) is especially important for most day-active lizards and chelonians for vitamin D3 synthesis and calcium regulation. [3]

[Paraphrased derived summary — non-Open-Access source.] Leopard geckos breed readily in captivity and are often ideal for novice owners; they need less special broad-spectrum lighting than many reptiles, but their insect diet needs regular calcium supplementation. [3]

[Paraphrased derived summary — non-Open-Access source.] It is caused by poor diet (low calcium:phosphorus ratio, vitamin D3 deficiency) or poor husbandry (no UVB light, insufficient heat). [7]

[Paraphrased derived summary — non-Open-Access source.] Critical cases need fluid therapy, nutritional support, and injectable calcium if blood calcium is low. [7]

[Paraphrased derived summary — non-Open-Access source.] Metabolic bone disease (MBD) is commonly seen in herbivorous lizards and chelonians and is associated with dietary calcium deficiency, a negative (low) calcium-to-phosphorus ratio, or lack of exposure to ultraviolet UVB radiation. [8]

Husbandry

The home is a terrestrial arid-scrub vivarium at 25–30°C and 20–30% humidity with a temperature gradient, broad-spectrum UVB, and a humid microclimate to aid shedding. [3]

Housing, environment and daily-care essentials for this species.

Leopard gecko environment — terrestrial arid scrub; POTZ 25–30°C, 20–30% humidity, insectivorous

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Leopard geckos are terrestrial arid-scrub lizards; recommended 25–30°C (77–86°F) at 20–30% relative humidity. [3]

All reptiles, including nocturnal and crepuscular species, benefit from broad-spectrum lighting; unfiltered sunlight is best, with artificial UVB bulbs as a useful alternative. [3]

Humid microclimates are often critical for arid species (e.g. tortoises, leopard geckos) to reduce shell pyramiding and abnormal sheds. [3]

Leopard gecko husbandry — few broad-spectrum lighting demands; humidity microclimate aids shedding

All lines in this block are paraphrased derived summaries — non-Open-Access source.

All reptiles, including nocturnal species, benefit from broad-spectrum lighting; unfiltered sunlight is best, with artificial UVB bulbs as a useful alternative. [3]

Reptile husbandry — class-level general rules (temperature, UVB, humidity, hides/enrichment, cohabitation)

Bearded dragons are terrestrial desert lizards; recommended 25–32°C (77–90°F) at 20–30% relative humidity.

Females prefer damp, humid environments for egg laying, (Hunziker 1994) and bury the eggs in the substrate (Henkel 1995). [1]

[Paraphrased derived summary — non-Open-Access source.] For some species, painting a solid black band 8 inches (20 cm) up from the cage bottom on the glass wall adds a sense of security. [2]

[Paraphrased derived summary — non-Open-Access source.] Smaller microhabitats inside the enclosure can raise humidity locally without making the whole cage humid. [2]

[Paraphrased derived summary — non-Open-Access source.] The enclosure should offer a temperature gradient spanning the species' preferred range from one end to the other, to keep occupants healthy. [2]

[Paraphrased derived summary — non-Open-Access source.] Under-tank heaters should cover no more than 30% of the enclosure floor, letting reptiles move away from the heat; they must be designed for reptile tanks. [2]

[Paraphrased derived summary — non-Open-Access source.] Furnishing the enclosure with appropriate cage furniture and hiding spaces helps lower stress and competition. [2]

[Paraphrased derived summary — non-Open-Access source.] Infrared panels come in many sizes and can be mounted on the cage roof to radiate heat downward. [2]

[Paraphrased derived summary — non-Open-Access source.] Diurnal, highly social species kept in groups need several separate basking (under a heat or UV bulb), feeding, and drinking stations positioned out of sight of dominant cagemates and human observers. [2]

[Paraphrased derived summary — non-Open-Access source.] Overcrowding must be avoided to limit stress and competition for food, water, basking spots, and mates. [2]

[Paraphrased derived summary — non-Open-Access source.] Many terrestrial, digging, or burrowing species need hiding places such as boxes, logs, rocks, or similar objects. [2]

[Paraphrased derived summary — non-Open-Access source.] If reptiles are cohabited, the enclosure must be large enough to give each animal its own perch and/or hiding area. [2]

[Paraphrased derived summary — non-Open-Access source.] A simpler substrate is easier to keep clean, which is itself a good reason to choose one. [2]

[Paraphrased derived summary — non-Open-Access source.] Newspaper is the preferred substrate for ill reptiles: it is cheap, easy to clean, and makes it easy to spot regurgitated food or droppings. [2]

[Paraphrased derived summary — non-Open-Access source.] Most reptiles favor overhead bulbs for basking heat and light, likely because this most closely mimics their natural environment. [2]

[Paraphrased derived summary — non-Open-Access source.] Basking lamps are the preferred heat/light source for turtles, tortoises, and lizards. [2]

[Paraphrased derived summary — non-Open-Access source.] Suitable basking lights include incandescent bulbs, infrared devices, mercury-vapor lamps (which supply both heat and UV), and ceramic heat emitters. [2]

[Paraphrased derived summary — non-Open-Access source.] Combined with a basking lamp, under-tank heaters can supply heat both day and night. [2]

[Paraphrased derived summary — non-Open-Access source.] Mercury-vapor lamps make excellent basking lights and also emit some natural-sunlight-type ultraviolet light, which reptiles require for health. [2]

[Paraphrased derived summary — non-Open-Access source.] Whatever lamp or heater is used, always measure the temperature just above the substrate where the animal rests to confirm it matches the species' correct basking temperature. [2]

[Paraphrased derived summary — non-Open-Access source.] Reptile housing requires a suitable enclosure plus sources of light, heat, and water. [2]

[Paraphrased derived summary — non-Open-Access source.] For many lizards, turtles, and tortoises, suitable substrates include potting soil, commercial leaf litter, and modest amounts of sand. [2]

[Paraphrased derived summary — non-Open-Access source.] Heat lamps must be used with great caution because overheating is a common hazard. [2]

[Paraphrased derived summary — non-Open-Access source.] Heat sources should connect to programmable thermostats that switch heat on or off automatically as the temperature falls too low or rises too high. [2]

[Paraphrased derived summary — non-Open-Access source.] Every enclosure should have at least two thermometers — one at the cool end away from the heat, one at the warm end near it — to verify the species' recommended temperature range is maintained. [2]

[Paraphrased derived summary — non-Open-Access source.] Under-tank heaters are also useful for lizards and snakes. [2]

[Paraphrased derived summary — non-Open-Access source.] Reducing ventilation to hold temperature and humidity is a bad idea and often causes skin and respiratory disease. [6]

Coarse sand, corncob bedding, and crushed walnut shells should never be used as leopard gecko substrate, because these bedding materials can be swallowed and will block the intestines. [9]

Wash greens used to gut-load feeder insects and keep household pesticides away from the enclosure, because pesticides can cause health issues in lizards. [9]

Lead and zinc are recognised reptile hazards: lead can come from old paint, ceramic food and water bowls, and lead-based materials, and zinc from some metals, so enclosures should use food-safe, lead-free materials. [9]

Behavior & Training

Leopard geckos are nocturnal and ground-dwelling; some reptiles are solitary and do better housed alone, while cohousing is possible only with no more than one male per group. [1] [2]

Socialisation, bonding, play and preventing boredom / behaviour problems.

Reptile — behavior (owner-practical care, Merck Veterinary Manual pet-owner)

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Some reptile species are solitary and do better housed alone. [2]

Cohousing same-species reptiles is sometimes possible, but a group should contain no more than one male, since males may fight. [2]

Full-spectrum light, which resembles natural sunlight and contains ultraviolet (UV) rays, improves feeding, activity, and to a lesser extent reproduction in reptiles. [2]

The daily light-dark cycle (photoperiod) influences the behavior and bodily functions of all animals. [2]

Feeding behavior and digestion are tied to environmental temperature. [2]

Humidity, light, food type, and the presence of other animals also shape feeding behavior. [2]

Temperament varies: aggression during mating and feeding is common in some semiaquatic turtles, some skinks and iguanas, and many other lizards and snakes. [2]

[Paraphrased derived summary — non-Open-Access source.] Aggressive species may need to be separated at feeding time to prevent injury to cagemates. [2]

Enrichment & Exercise

Toys, foraging, hiding and exercise to prevent boredom.

Reptile — enrichment (owner-practical care, Merck Veterinary Manual pet-owner)

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Arboreal (tree-dwelling) species should be given horizontal and vertical branches or other suitable climbing material. [2]

Because of these needs, reptiles suit adults or older children who enjoy observing them rather than handling them. [2]

When to call a vet NOW

Leopard geckos are reptiles, and the manual advises contacting a species-experienced veterinarian promptly when worrying signs appear. [3]

• If UVB or calcium supplementation has lapsed: leopard geckos use UVB radiation for vitamin D3 synthesis, and vitamin D is an important regulator of calcium and phosphorus homeostasis — if lighting or supplementation has slipped, have a species-experienced vet check the gecko. [10]
• Progressive weight loss / wasting: Cryptosporidium varanii infection in leopard geckos is associated with wasting syndrome — book a vet visit if the gecko keeps losing weight or condition. [10]
• A gravid female that cannot lay: dystocia (egg retention) is a multifactorial, life-threatening condition commonly affecting pet reptiles — call a vet immediately. [10]
• Zoonosis hygiene: leopard geckos can harbor antimicrobial-resistant bacteria, carrying zoonotic risk — wash hands after handling and seek medical advice if illness follows contact. [10]

Health & Disease

The recurring themes are metabolic bone disease from calcium/vitamin D3 deficiency and parasite-driven wasting (Cryptosporidium varanii). [10]

Common conditions and their clinical signs, drawn from professional veterinary references. If you notice worrying signs, contact a species-experienced veterinarian promptly.

Leopard gecko health — hypovitaminosis A in insectivorous lizards; beta-carotene not metabolized

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Hypovitaminosis A is common in aquatic turtles and insect-eating lizards fed diets low in preformed vitamin A; the common beta-carotene supplement cannot be converted to vitamin A by many reptiles. [7]

Reptile dysecdysis — abnormal shedding and retained skin

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Humidity needs are considerably higher while a reptile is shedding (ecdysis). [6]

High humidity has long been seen as essential for many tropical species (e.g. chameleons); but humid microclimates are also often critical for many arid species (e.g. tortoises, leopard geckos) to reduce shell pyramiding and abnormal sheds. [6]

Reptile husbandry essentials — UVB (290–300 nm) for vitamin D3/calcium, species-specific temperature gradients

The temperature figures given are air-temperature gradients. [3]

Reptile metabolic bone disease — secondary nutritional hyperparathyroidism from low Ca:P / no UVB

All lines in this block are paraphrased derived summaries — non-Open-Access source.

Secondary nutritional hyperparathyroidism is the most common bone disease seen in reptile practice. [7]

[Paraphrased derived summary — non-Open-Access source.] Reptiles with very soft jaw bones cannot chew and must receive liquid food via stomach tube or oral syringe. [2]

Toxicology & Hazards

Substances and environmental hazards to avoid.

Leopard gecko keeper-practical toxicology & hazards (VCA; ASPCA Pro; PetMD; Merck Veterinary Manual)

Fireflies (Photinus spp.) contain lucibufagins and are highly toxic to lizards; ASPCA notes death can occur within 2 hours of exposure, so fireflies must never be fed to leopard geckos. [9]

Reptile metabolic bone disease (MBD) — calcium deficiency / low Ca:P / lack of UVB; pliable jaws, fractures, shell abnormalities

All lines in this block are paraphrased derived summaries — non-Open-Access source.

MBD is commonly seen in juvenile reptiles. [8]

PMID 41852150 (2026, Journal of anatomy) — [Paraphrased derived summary — non-Open-Access source.] Comparing three developmental timetables—absolute days, embryonic size, and developmental stage—for ordering cranial ossification events in leopard gecko (Eublepharis macularius) embryos, the authors found that staging by developmental stage gave the least variability and the finest resolution, outperforming day- and size-based ordering. They also achieved better cranial-mineralization resolution for this species than previously reported for geckos generally, especially when specimens were ordered by stage; the excerpt is cut off before details of embryo subdivision.

PMID 40755204 (2025, Veterinary radiology & ultrasound: the official journal of the American College of Veterinary Radiology and the International Veterinary Radiology Association) — [Paraphrased derived summary — non-Open-Access source.] A 17-year-old intact male leopard gecko (Eublepharis macularius) presented with lethargy, abdominal distension, and rapid weight loss; ultrasound revealed a 19×14×14 mm pericardial mass with substantial effusion causing cardiac tamponade and suspected right-sided congestive heart failure. Postmortem examination and histopathology confirmed pericardial mesothelioma with hemopericardium and pericardial adhesion. The authors report this as the first case with antemortem treatment and postmortem definitive diagnosis of pericardial mesothelioma in a leopard gecko. [15]

PMID 39876039 (2025, Journal of dental research) — Molecular Profiling of Odontoclasts during Physiological Tooth Replacement. (opening): The odontoclast is a rarely studied cell type that is overly active in many dental pathologies, leading to tooth loss. It is difficult to find diphyodont mammals in which either physiological or pathological root resorption can be studied. Here we use the adult leopard gecko, which has repeated cycles of physiological tooth resorption and shedding. RNA-seq was carried out to compare gene expression profiles of functional teeth to developing teeth. Genes more highly expressed in bell-stage developing teeth were related to morphogenesis ( PTHLH, SFRP2, SHH, EDAR ). Some genes expressed in osteoclasts ( ACP5, CTSK, CSF1R ) were relatively more abundant in functional teeth compared with developing teeth. There was, however, no differential expression of RANKL ( TNFSF11 ) in the 2 tooth types. In addition, functional teeth expressed proteolysis genes not found in osteoclasts ( ADAMTS2, 3, 4, 14; CTSA, CTSH, CTSS ). We used tartrate acid resistant phosphatase and cathepsin K (CTSK) staining to identify odontoclasts in and around the gecko dentition. There were 3 populations of CTSK cells: (1) large, functional multinucleated odontoclasts in the crown of the tooth with a ruffled border inside resorption pits; (2) smaller, precursor cells in the pulp with fewer nuclei; and (3) flattened external precursor cells next to the root and bone of attachment. We found a positive relationship between developing teeth and the population of CTSK+ cells on the root surface. We tested a candidate signal that may be involved in CTSK+ cell presence. An antagonist of CSF1R was delivered to developing teeth in vivo, which resulted in a significant decrease in CTSK and CSF1R compared with DMSO controls. Thus, the CSF1 signaling pathway is upstream of CTSK in teeth. This is the first work to detail the molecular characteristics of odontoclasts during physiological tooth shedding and to demonstrate that in vivo, local drug delivery is possible in the gecko model.

PMID 37981904 (2023, Veterinarni medicina) — Malignant ovarian dysgerminoma in a 16-year-old leopard gecko ( Eublepharis macularius ). (opening): The 16-year-old female leopard gecko ( Eublepharis macularius ) was presented with distended coelom and cachexia. Examination of the faecal sample ruled out the presence of protozoan parasites. A radiographic examination confirmed the presence of radiopaque foreign material in the intestine. The conservative treatment with tramadol, butylscopolamine, famotidine, vitamin B complex, and supportive fluid therapy with Hartmann solution and Duphalyte, was performed for 14 days. Ultrasonographic examination revealed the presence of a large mass adherent to the liver (with hypoechoic regions), a thin-walled cystic structure close to the liver, and coelomic effusion. Surgical exploration revealed a large mass on the right ovary. The unilateral (right) ovariectomy was performed. Histologic examination of the mass revealed dysgerminoma with an invasion of the ovarian bursa and blood vessels. Nine months after the surgery the patient was active and doing well. In reptiles, dysgerminoma is an uncommon type of neoplasia. To the best of our knowledge, this is the first case of dysgerminoma tumour diagnosed intravitally and treated successfully in lizards.

PMID 36899783 (2023, Animals: an open access journal from MDPI) — Egg Removal via Cloacoscopy in Three Dystocic Leopard Geckos ( Eublepharis macularius ). (opening): Dystocia is a multifactorial, life-threatening condition commonly affecting pet reptiles. Treatment for dystocia can be either medical or surgical. Medical treatment usually involves the administration of oxytocin, but in some species or, in some cases, this treatment does not work as expected. Surgical treatments such as ovariectomy or ovariosalpingectomy are resolutive, but invasive in small-sized reptiles. In this paper, we describe three cases of post ovulatory egg retention in three leopard geckos ( Eublepharis macularius ) successfully treated through a cloacoscopic removal of the retained eggs, after a non resolutive medical treatment. The intervention was fast, non-invasive, and no procedure-related adverse effects were noted. The problem relapsed six months later in one animal, and a successful bilateral ovariosalpingectomy was performed. Cloacoscopy should be considered a valuable, non-invasive tool for egg removal in dystocic leopard geckos when the egg is accessible to manipulation. Recrudescence or complications such as adhesions, oviductal rupture, or the presence of ectopic eggs should recommend surgical intervention. [CC BY — Open Access, verbatim with attribution.] [18]

PMID 41986369 (2026, NPJ Regenerative medicine) — Heart ventricle regeneration in the lizard Eublepharis macularius, the leopard gecko. (opening): Among mammals, injury to the heart typically results in scar formation and diminished cardiovascular function. In contrast, some teleost fish and salamanders can replace damaged heart tissue and restore overall function. For most species, however, less is known. Here, we investigate cardiac self-repair in an amniote capable of multi-tissue regeneration, the leopard gecko (Eublepharis macularius). To create a heart lesion, we placed a liquid nitrogen-cooled metal probe directly onto the ventricle. The result was a cryoinjury to ~20% of the ventricle. Cardiac cryoinjury induced localized cardiac cell death, followed by an increase in cell proliferation by injury-adjacent cardiomyocytes and non-cardiomyocytes. By 100 days, the histology of the ventricular myocardium was nearly completely restored. Echocardiography and invasive hemodynamic monitoring demonstrated that global cardiac function is restored within this timeframe, verifying functional replacement of the myocardium. To explore the molecular basis, we performed bulk RNA sequencing of the injury-adjacent tissue and found that many of the molecular mechanisms common to other cardiac regenerating species, including genes involved in heart development, glycolysis, and extracellular matrix deposition, are also conserved in geckos. Taken together, this work expands the comparative framework of heart regeneration to include reptiles and indicates that the ability to replace missing or damaged cardiomyocytes is shared across >50 million years of evolution.

PMID 41730629 (2026, The Journal of veterinary medical science) — Localized oral histiocytic sarcoma in a leopard gecko (Eublepharis macularius). (opening): A two-year-old female leopard gecko presented with a mass in the oral cavity with apparent exophthalmos. Despite medical management, the animal died. Grossly, the firm and tan to white mass extended from the oropharyngeal region to the external surface overlying the cornea of the left eye. Histologically, the mass was a poorly-demarcated, densely cellular, invasive neoplasm. The neoplasm was composed of solid sheets and interlacing bundles of round, polygonal, and short spindle-shaped cells. Immunohistochemically, the neoplastic cells were positive for Iba-1 and CD204. These findings were consistent with a localized histiocytic sarcoma. This is the first documentation of the gross, histopathological, and immunohistochemical features of localized histiocytic sarcoma in a leopard gecko.

PMID 41183498 (2026, Genetics) — Candidate genes underlying hypomelanistic morphs in squamate reptiles. (opening): Skin coloration is crucial for the survival of animals and ranges from spectacular colorful displays used to attract a mate to cryptic camouflage used to avoid predators. Among the 3 main types of chromatophores, melanophores are the most widespread in vertebrates and can set the skin tone by the amount of melanin they produce and store in dedicated vesicles, the melanosomes. Mutations associated with melanophore differentiation and maturation result in hypomelanistic and amelanistic phenotypes, both extensively studied in mammals but less so in snakes and lizards. Here, we characterize at the genomic, transcriptomic, and histological level, the Hypomelanistic corn snake morph and 3 hypomelanistic leopard gecko morphs. To minimize bias in studying leopard gecko color morphs, we first assembled a chromosome-level genome from a wild-type individual in terms of coloration. We propose that candidate mutations in 3 melanogenesis factors generate these phenotypes: (i) tyrosinase (TYR), an essential enzyme for melanin synthesis, (ii) NCKX5 (SLC24A5), an ion exchanger involved in melanosome maturation, and (iii) the P protein (OCA2), a transmembrane transporter for tyrosine. Our extended bulk RNA sequencing analyses show that additional pigmentation-related genes, affecting melanin production, melanosome motility, and melanophore migration, are dysregulated in the embryonic skin of the mutated animals. This observation highlights the likely associations among the corresponding pathways and is in line with our electron microscopy imaging results. Indeed, the subcellular structure of melanophores is uniquely altered at each of the 4 morphs and likely reflects a multigenic effect. These findings demonstrate that conserved pigmentation genes can produce species-specific effects, underscoring the modular nature of skin coloration in vertebrates. Our work establishes reptiles as comparative models for studying pigment cell biology and reveals evolutionary flexibility in the genetic regulation of melanogenesis.

PMID 42071922 (2026, Animals: an open access journal from MDPI) — Could Spatial Learning in the Early Stages of Life Consistently Affect the Long-Term Memory of Leopard Geckos (Eublepharis macularius)?. (opening): (1) Background: This study investigates the development of spatial navigation and long-term memory in the leopard gecko ( Eublepharis macularius ) to address gaps in understanding reptilian cognitive ontogeny. We aimed to determine if early-life training enhances long-term memory retention and to evaluate the repeatability of individual cognitive performance over time. (2) Methods: Using a modified Morris Water Maze with visual landmarks, we tested 39 individuals across three life stages: juveniles (20 trials), subadults, and adults (10 trials in each later phase). Long-term memory retention was assessed after four and fourteen months. (3) Results: A strong learning effect was observed during the juvenile stage, with geckos significantly improving speed and navigational efficiency. Spatial memory remained stable at the subadult stage (four months post-training), but declined significantly by adulthood (fourteen months post-training), returning to baseline levels. Individual success rates were significantly repeatable during juvenile (R = 0.192) and subadult phases (R = 0.071), although this consistency disappeared in adulthood. (4) Conclusions: These findings indicate that leopard geckos possess substantial spatial learning abilities early in life and exhibit individual cognitive differences. However, spatial memory decays over time without reinforcement. The results highlight the importance of considering developmental stages when evaluating the evolutionary and ecological constraints of reptilian cognition.

PMID 40370835 (2025, Frontiers in veterinary science) — ESBL/pAmpC-producing Enterobacterales in common leopard geckos (Eublepharis macularius) and central bearded dragons (Pogona vitticeps) from Portugal. (opening): Common leopard geckos ( Eublepharis macularius ) and central bearded dragon ( Pogona vitticeps ) are widely kept as pets but can harbor pathogenic bacteria, including antimicrobial-resistant (AMR) bacteria. This study aimed to research the frequency of β-lactamase-producing Enterobacterales in these two reptile species. A total of 132 samples were collected from the oral and cloacal cavities of healthy common leopard geckos and central bearded dragons in the Lisbon area, Portugal. Antimicrobial resistance was assessed for third-generation cephalosporin (3GC)-resistant Enterobacterales. The results revealed that 3GC-resistant Enterobacterales were observed in 17.9% ( n = 14/78) of the reptiles. The most commonly identified species were: Citrobacter freundii and Klebsiella aerogenes. Furthermore, some isolates produced extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases (AmpC) encoding genes such as bla CMY-2, bla CTX-M-15, and bla TEM-1. These findings emphasize the potential role of these reptiles in the spread of AMR bacteria, particularly in urban settings where human- animal interactions are frequent. Given the zoonotic risks, this study emphasizes the importance of continued surveillance and responsible antimicrobial use in both veterinary and human medicine to mitigate the spread of AMR bacteria.

PMID 39468396 (2025, Journal of anatomy) — Bone labeling experiments and intraskeletal growth patterns in captive leopard geckos (Eublepharis macularius). (opening): An understanding of the dynamics of bone growth is key to interpreting life-history parameters of vertebrates. In this study, we used fluorochrome labels in captive leopard geckos (Eublepharis macularius) to track bone growth and intraskeletal variability from embryonic to adult growth stages. Thirteen individuals were administered fluorochromes from pre-hatching to 4 years of age. The left tibia, fibula, femur, humerus, radius, and ulna were examined histologically and compared for differences in the number of labels within and between individuals at each sampled growth stage, and the amount of bone growth between labels was calculated. Results suggest that limb elements had differing growth rates; the fibula grew the fastest per day on average and the femur grew the slowest per day on average. All labels administered in ovo were still present in all limb elements in adults except for the tibia, suggesting growth marks are not lost in most elements and accurate calculations of growth rates could be performed in individuals up to 3 years old. All ex ovo labels were accounted for; however, when two fluorochromes were administered 3 weeks apart, the labels could not be differentiated from each other due to the new bone not being deposited at a quantifiable level. Overall, the tibia in leopard geckos is the least reliable limb bone to use for skeletochronology and the humerus, radius, and fibula preserve the longest growth record. This research highlights that, as in other extinct and extant animals, patterns of bone growth are not consistent across reptiles. This study adds to the growing body of knowledge on growth variability in reptiles. [CC BY — Open Access, verbatim with attribution.] [25]

PMID 39841034 (2025, Parasitology) — Passage of Angiostrongylus cantonensis through the trophic web: an experimental study on reptiles. (opening): The rat lungworm Angiostrongylus cantonensis is a zoonotic metastrongyloid nematode, currently considered an emerging pathogen approaching Europe. In tropics and subtropics, it is an important food-borne neurotropic parasite of medical and veterinary importance. Sources of infection for mammals and birds include gastropod intermediate hosts and poikilothermic vertebrates (paratenic hosts). To evaluate the relevance of reptiles in the rat lungworm circulation, we performed an experimental series focused on long-term survival of third stage larvae (L3) of A. cantonensis in reptiles and potential of saurians to serve as a source of infection for further hosts. Twenty leopard geckos ( Eublepharis macularius ) were infected with varying doses of L3 (100, 1000, 10 000 larvae per animal). Live L3 were collected from all infected geckos (mostly in musculature and liver) euthanized 1-6 months after the infection and were proven to be infective for Wistar rats (definitive hosts). Three sacrificed geckos were subsequently fed to three corn snakes ( Pantheropis guttatus ) to test hypothesis of L3 infectivity for predators positioned higher in the food chain. Snakes were euthanized 1 month post-infection and live L3 were detected predominantly in the intestinal wall. The animals remained clinically healthy throughout the study. No reptiles showed significant changes in haematological and biochemical blood parameters, though elevated CK and GLDH were observed in most geckos in the group receiving higher infectious dose. This study highlights the significant potential of reptiles to play a crucial role in the circulation of metastrongyloid nematodes in food web and in their transmission to humans.

PMID 40723477 (2025, Animals: an open access journal from MDPI) — Memory in Leopard Geckos (Eublepharis macularius) in a Morris Water Maze Task. (opening): The spatial orientation of mammals and birds has been intensively studied for many years, but the cognitive mechanism of spatial orientation and memory used by squamates remains poorly understood. Our study evaluated the learning and memory abilities of leopard geckos ( Eublepharis macularius ) in an adapted Morris water maze. The animals learned during the training phase consisted of 20 trials. To assess long-term memory, we retested geckos twice after several months. The geckos remembered the learned information in a short re-test after two months, but after four months, they required retraining to find the platform. We hypothesise that the duration of memory corresponds with short-term changes in semi-desert environments within one season, while disruption of memory performance after a six-month gap may simulate the more extensive seasonal change in spatial relationships in their natural environment. Moreover, during the winter period, geckos exhibit low activity, which can be connected with decreased frequency of foraging trips. Therefore, the memory loss after four months may reflect the low level of memory jogging. The motivation during the experiment was the crucial parameter of learning and memory processes. In later phases, geckos were less motivated to perform the task. Finally, they relearned the spatial orientation task, but they moved more slowly as the experiment progressed.

PMID 40818077 (2025, Veterinary radiology & ultrasound: the official journal of the American College of Veterinary Radiology and the International Veterinary Radiology Association) — Comparative Sonographic Studies of the Urogenital Tract in Lizards. (opening): The assessment of the urogenital tract is of great importance in the diagnosis of diseases in lizards, and sonographic examination is the most suitable imaging method for this purpose. However, reference data are not available for most of the commonly kept species. The objective of this prospective anatomical analytical study was to sonographically examine the urogenital tract of four of the most commonly kept lizard species and compare their kidneys, testes, and ovaries. A total of 41 lizards, 14 bearded dragons (Pogona vitticeps), 15 leopard geckos (Eublepharis macularius), seven veiled chameleons (Chamaeleo calyptratus), and five panther chameleons (Furcifer pardalis) were included. An 8-18 MHz field hockey stick transducer and a 6-15 MHz linear transducer were used. Sagittal and transverse images of the organs were recorded. The kidneys could be visualized and assessed in full length in all lizards, the testes in 18 of 19, and the ovaries in 13 of 22 lizards. The results of the current study could serve as reference values for future studies on the species mentioned. [CC BY — Open Access, verbatim with attribution.] [28]

PMID 40088131 (2025, Developmental dynamics: an official publication of the American Association of Anatomists) — Squamate ventricular cardiomyocytes: Ploidy, proliferation, and heart muscle cell size in the leopard gecko (Eublepharis macularius). (opening): Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury. For example, among non-regenerating taxa like adult mammals and birds, cardiomyocytes are polyploid, rarely proliferate, and are large in size. In contrast, in regeneration-competent zebrafish and amphibians, cardiomyocytes are diploid, spontaneously proliferate, and are comparatively small. For other species, less is known. Results Here, we investigate these attributes in the squamate Eublepharis macularius, the leopard gecko. Using the nuclear counterstain DAPI to measure fluorescence intensity as a proxy for DNA content, we found that >90% of adult cardiomyocytes are diploid. Using serial histology and immunostaining for markers of DNA synthesis and mitosis, we determined that adult gecko cardiomyocytes spontaneously proliferate, albeit at significantly lower levels than previously reported in subadults. Furthermore, using wheat germ agglutinin, we found that the cross-sectional area is maintained across ontogeny and that gecko cardiomyocytes are 10× smaller than those of mice. Conclusions Taken together, our data show that gecko cardiomyocytes share several key cellular attributes with regeneration-competent species and that postnatal ventricular growth occurs via cardiomyocyte hyperplasia.

PMID 41316997 (2026, Journal of anatomy) — Budding, fission, and fusion: Unveiling patterns shaping pancreatic islet size and distribution in squamate reptiles. (opening): A growing body of evidence suggests that lizards are promising model organisms for studying various developmental processes. However, knowledge of pancreatic islet distribution in non-ophidian squamates remains limited. The most comprehensive accounts available to date lack three-dimensional reconstructions and often show inconsistencies. In this study, we aimed to address both aspects: first, by evaluating squamate embryos as model systems for understanding general mechanisms of pancreatic islet morphogenesis in vertebrates, and second, by conducting a comparative analysis of islet development in squamates from an evolutionary perspective. In this study, we analyzed embryos of four non-ophidian squamates representing three major evolutionary lineages: Iguania-the brown anole Anolis sagrei; Gekkota-the leopard gecko Eublepharis macularius and the mourning gecko Lepidodactylus lugubris; and Lacertidae-the sand lizard Lacerta agilis. Three-dimensional reconstructions were created from thick serial sections and high-resolution semithin sections. Pancreatic islet cells in lizards originate from ductal epithelium. Early in development, precursor cells leave the duct walls to form buds that give rise to primary islets, a process evolutionarily conserved across vertebrates. Subsequent growth involves both the fusion of islet buds and the fission of larger agglomerates. Analyzed species differ in islet distribution: The brown anole islet remains restricted to the splenic lobe, whereas the sand lizard, leopard gecko, and mourning gecko also form islets in remaining regions. In studied gekkotans, small- and medium-sized islets tended to be concentrated in close proximity to the spleen. Medium-sized islets dominate the splenic lobe in the sand lizard. Interestingly, we observed a varanid-like condition in the brown anole, characterized by the formation of a single large islet within the splenic lobe, accompanied by a concurrent reduction in islet size throughout the remaining pancreatic regions. This pattern may reflect a broader trend within Toxicofera, a clade identified through molecular studies, toward splenic lobe islet enlargement and a reduction in the size of the islets in the remaining parts of the pancreas. While the phylogenetic position may influence these patterns, our findings suggest that the spatial relationship between the spleen and pancreas, particularly the formation of large islets near the spleen, could play a more direct, possibly inductive, role in islet formation. Further detailed studies, particularly focusing on representatives of Iguania and Anguimorpha, are essential to test this hypothesis. [30]
