Description de l'espèce
Geographical Origin and Habitat: Native to northern and northwestern Madagascar. It inhabits dry deciduous forests and humid tropical lowlands, living high in the canopy on large tree trunks and branches.
Taxonomy and Genetics: Family Gekkonidae, genus Blaesodactylus. One of the largest gecko species in Madagascar. Genetically adapted to arboreal life in dry and wet forest zones, possessing specialized scales for camouflage.
Behavior and Habits: Nocturnal and arboreal. During the day, they press flat against bark to hide. When threatened, they exhibit aggression, gaping their mouth and producing a loud barking or growling sound, and can deliver a painful bite.
Morphology: A large and robust gecko, reaching a total length of 28 to 30 cm. Features a thick, muscular head, large eyes with vertical pupils, and bark-like grey-brown mottled skin that provides excellent camouflage.
Soins, reproduction et cohabitation
Terrarium Setup: Requires a tall vertical terrarium (minimum 60x45x90 cm) for a single adult. Furnish with thick vertical cork bark tubes, sturdy branches, and broad-leafed artificial or live plants. Use a moist soil-bark mix substrate.
Lighting and Heating: Basking zone temperature of 31-32°C (88-90°F) using a basking light, with an ambient temperature of 25-27°C (77-80°F) and night drop to 20-22°C (68-72°F). Provide low-level UVB lighting (5%) to support calcium metabolism.
Humidity and Hydration: Maintain relative humidity between 60% and 80%. Mist the terrarium thoroughly once or twice daily. This provides drinking water droplets on leaves and glass, and maintains proper air humidity for skin shedding.
Feeding and Supplementation: Opportunistic carnivore. Feed large gut-loaded roaches, crickets, locusts, and occasional snails or hornworms. Dust prey with calcium and Vitamin D3 twice a week, and add a multivitamin supplement once a week.
Compatibility: Strictly solitary. Males are highly territorial and will fight aggressively. Females can also show territoriality. House individually, and only pair for short breeding intervals under direct observation.
Health and Common Diseases: Metabolic Bone Disease (MBD) is a major risk if calcium supplementation or UVB is lacking. Inadequate humidity leads to dysecdysis (shed retention), particularly around toes and eyes. Respiratory infections can develop if enclosure is cold and wet.

Profil de reptile
- Régime alimentaire
- Insectivore
- The diet of Blaesodactylus boivini consists primarily of appropriately sized insects such as crickets, mealworms, and dubia roaches. In the wild, they are opportunistic ambush predators that consume any small invertebrate they can overpower. It is crucial to gut-load all feeder insects and dust them with high-quality calcium and multivitamin supplements before offering them to ensure proper nutritional balance.

- Mode de vie/microhabitat
- Arboreal
- The lifestyle of Blaesodactylus boivini is deeply tied to its natural habitat, whether that involves climbing vertical surfaces or dwelling among leaf litter. They utilize their specialized anatomical adaptations, such as toepads or claws, to navigate their surroundings efficiently. A properly structured enclosure that mimics their native environment is essential for their physical and mental well-being.
- Cycle d'activité
- Nocturnal
- As a species adapted to specific environmental conditions, Blaesodactylus boivini displays distinct activity patterns. They often emerge during periods of optimal temperature and humidity to forage for food and patrol their territory. Providing a naturalistic light cycle helps regulate their circadian rhythm and promotes natural behaviors in captivity.
- Sociabilité
- Tolerant
- Blaesodactylus boivini exhibits fascinating behavioral traits, often relying on camouflage and stealth to avoid predators and ambush prey. They may display territorial behaviors, particularly among males, making it advisable to house them individually or in carefully monitored harems. Vocalizations and tail movements are frequently used as communication tools within their environment.
- Reproduction
- Oviparous
- Breeding Blaesodactylus boivini typically occurs after a cooling period, with females laying small clutches of one to two eggs. These eggs are usually deposited in a secure, slightly moist location within the enclosure. Incubation temperatures directly influence the development time and, in some species, the sex of the hatchlings, requiring careful monitoring.
- Tolérance aux manipulations
- With caution
- Handling Blaesodactylus boivini requires a gentle and patient approach, as they can be easily stressed or injured if restrained improperly. It is best to allow them to walk freely from hand to hand rather than grasping them firmly. Over-handling should be avoided to prevent autotomy (tail dropping) and minimize unnecessary stress on the animal.
- Brumation
- Depending on its geographic origin, Blaesodactylus boivini may undergo a period of brumation during the cooler months. During this time, their metabolism slows down significantly, and they may refuse food while seeking a cool, dark place to rest. Providing a controlled drop in temperature and reducing feeding frequency safely simulates this natural winter resting phase.
- Mue
- Periodic
- Like all reptiles, Blaesodactylus boivini must periodically shed its skin to accommodate growth and replace worn tissue. A successful molt requires adequate environmental humidity and access to a rough surface to help loosen the old skin. It is important to inspect the animal after shedding to ensure no retained skin remains, particularly around the toes and eyes, which could cause circulation or vision issues.
