Descrição da espécie
Geographical Origin and Habitat: Endemic to the dense, humid rainforest canopies of New Caledonia, specifically the Mt. Koghis region on the main island (Grande Terre). They reside high in the tree hollows of primary forests, rarely descending to the ground.
Taxonomy and Genetics: Family Diplodactylidae. *Rhacodactylus leachianus* (Mt. Koghis) is a mainland (Grande Terre) locale of the giant gecko. Captive breeding lines are carefully cataloged to preserve geographic purity, preventing hybridization between island and mainland locales.
Behavior and Habits: Nocturnal and arboreal, spending the day hidden in hollow tree trunks. They are highly territorial and vocal, producing growling, whistling, or barking sounds when disturbed. They are skilled climbers, using their wide adhesive toe pads and clawed feet.
Morphology: The largest living gecko species, with Mt. Koghis specimens reaching lengths of 30–35 cm and weighing over 300 grams. Characterized by a massive head, loose, heavily wrinkled skin on the flanks, and a short, stubby tail. Males are generally larger with a distinct hemipenal bulge at the base of the tail.
Cuidado, criação e companheiros de tanque
Terrarium Setup: Requires a large, robust, and vertically oriented terrarium (minimum 60x45x90 cm for an adult). Furnish with large, thick hollow cork tubes or bamboo logs placed diagonally, as thin branches cannot support their weight. Use broad-leafed plants and a moisture-retaining substrate like forest soil and moss.
Lighting and Heating: Maintain a moderate temperature range between 22°C and 26°C. Temperatures must never exceed 28°C, as overheating can cause lethal heat stress. Provide low-output (5%) UVB lighting to ensure proper calcium absorption and prevent metabolic bone disease (MBD).
Humidity and Hydration: Keep relative humidity high (60–80%) through heavy evening misting. Good ventilation via a mesh top is crucial to prevent stagnant air, which leads to bacterial or fungal skin infections. The gecko will drink droplets from glass walls and leaves.
Feeding and Supplementation: Primarily frugivorous in captivity. The main diet (70%) must consist of high-quality commercial gecko powdered diets (Pangea or Repashy) mixed with water, offered in elevated feeding ledges. Supplement weekly with gut-loaded, calcium-dusted insects (such as large roaches or locusts).
Compatibility: Must be kept individually. Adult geckos are highly territorial, and housing multiple individuals (especially males) together will result in severe, potentially fatal aggression. Breeding pairs should only be introduced under experienced supervision.
Health and Common Diseases: Skin infections can occur if the terrarium is kept wet and stagnant without drying cycles. Handle with care; while they are generally docile outside their territory, they can defend their cage aggressively. Never grab them by the tail, as they may drop it (autotomy), and it will not regenerate.

Perfil de réptil
- Dieta
- Omnivore
- The New Caledonian Giant Gecko, commonly known as the Leachie, is an omnivore with a distinct preference for frugivory. In its natural island habitat, it consumes a wide variety of overripe fruits, nectar, and sap, supplementing its diet with large insects, smaller lizards, and occasionally small birds or mammals. In captivity, they are typically maintained on high-quality, commercially prepared fruit-based gecko diets, supplemented with appropriately sized live insect prey.

- Estilo de vida/Microhabitat
- Arboreal
- The largest extant gecko species, capable of producing loud vocalizations. As a highly adapted arboreal species, the Rhacodactylus Leachianus utilizes its environment to the fullest. This lifestyle requires a terrarium setup that mimics such conditions, focusing on vertical space and climbing structures. Proper enrichment should be provided to allow for natural behaviors.
- Ciclo de atividades
- Nocturnal
- The Rhacodactylus Leachianus is predominantly nocturnal in its natural habitat. It typically exhibits its highest levels of activity during the night, emerging to forage for food and explore its surroundings while resting during the alternating periods to conserve energy and avoid predators.
- Socialidade
- Gregarious
- Leachies are strictly solitary and highly territorial, known for being quite vocal and occasionally aggressive. They emit a range of sounds including clicks, squeaks, and deep growls to assert territory or express displeasure. Due to their formidable jaws and strong territorial instincts, adults should be housed individually unless a carefully bonded breeding pair is established, as severe fighting or death can occur otherwise.
- Reprodução
- Oviparous
- Leachianus geckos are oviparous, laying two large eggs per clutch. Females deposit the eggs in moist substrate, usually within tree hollows or the forest floor in the wild. Incubation is notoriously long and temperature-dependent, often taking anywhere from 60 to 90 days, and sometimes longer. Breeding these geckos requires careful introduction, as incompatible pairs can inflict serious injuries on one another during courtship.
- Tolerância de tratamento
- Expert only
- When it comes to interactions, the Rhacodactylus Leachianus is generally considered defensive. It may exhibit defensive behaviors when threatened, so handling should be done cautiously or avoided altogether.
- Brumação
- Não obrigatório
- Regarding seasonal cycles, brumation is optional for the Rhacodactylus Leachianus. A cooling period is optional and primarily used by breeders to stimulate reproductive behaviors, though it is not strictly necessary for the animal’s general well-being.
- Muda
- Periodic
- The Rhacodactylus Leachianus requires high humidity conditions for a successful molt. Adequate moisture is critical; providing a humid hide and regular misting ensures the shedding process goes smoothly without stuck sheds.
