Amboina Sailfin Lizard
Hydrosaurus amboinensis
This magnificent, large semi-aquatic agamid lizard originates from Indonesia. It is particularly famous for the impressive sail-like crest present on the tail of mature adult males.

Descrição da espécie
Geographical Origin and Habitat: Native to eastern Indonesia (specifically the Moluccas, including Ambon Island) and parts of New Guinea. It inhabits dense rainforests, strictly along the margins of rivers, streams, and freshwater coastal marshes.
Taxonomy and Genetics: Belongs to the family Agamidae, genus Hydrosaurus. It is the largest member of the sailfin dragon group. Recent phylogenetic research has resolved taxonomic confusion, separating this species from H. pustulatus.
Behavior and Habits: Diurnal, semi-arboreal, and semi-aquatic. These lizards are highly active and are exceptional swimmers, using their flattened tails for propulsion. When startled, they jump from overhanging branches into the water to hide.
Morphology: Adults can grow up to 100-110 cm in total length. Body is olive-green to dark grey with black mottling. Mature males develop a large, fan-like sail on the base of their tail, supported by elongated neural spines.
Cuidado, criação e companheiros de tanque
Terrarium Setup: An exceptionally large custom enclosure is required (minimum 200x100x200 cm for an adult). It must feature a substantial aquatic section (at least 40 cm deep) with a powerful canister filter, and thick branches for climbing.
Lighting and Heating: Provide high-intensity UVB lighting and basking spots. Basking area should reach 35-38°C (95-100°F) using halogen floodlights. Maintain ambient day temperature of 28-30°C (82-86°F) and a night drop to 22°C (72°F).
Humidity and Hydration: Maintain high humidity levels between 75% and 85% using misting systems or frequent manual spraying. The water pool provides primary hydration, and because they defecate in water, daily water changes are necessary.
Feeding and Supplementation: Omnivorous. Juveniles eat mostly insects (crickets, roaches, locusts). Adults transition to a diet heavy in leafy greens, dandelion, and tropical fruits, supplemented with fish or earthworms. Dust food with calcium and D3.
Compatibility: Males are territorial and will fight. Best kept individually or in a harem of one male and two females in a massive enclosure. They are shy and easily stressed, so handling should be kept to a minimum to avoid panic.
Health and Common Diseases: Prone to Metabolic Bone Disease (MBD) if UVB or calcium is lacking. Nose rubbing against glass is common if the enclosure is too small or if they feel insecure; provide visual barriers. Good ventilation is critical.

Perfil de réptil
- Dieta
- Omnivore
- The Amboina Sailfin Lizard is an omnivorous reptile that consumes a highly varied diet dictated by its riverine habitat. Juveniles are primarily insectivorous, relying on high-protein prey like crickets and roaches to fuel their rapid growth. As they mature, their diet shifts significantly toward plant matter, including leaves, aquatic plants, fruits, and flowers, supplemented by occasional crustaceans or small fish.
- Tamanho adulto
- 100 cm
- Estilo de vida/Microhabitat
- Semi-aquatic
- These are massive, semi-aquatic lizards. Their enclosures must accommodate a large swimming area as well as strong branches overhanging the water.
- Ciclo de atividades
- Diurnal
- Sailfin lizards are extremely active and diurnal, basking under intense sunlight and rapidly diving into water when startled.
- Socialidade
- Solitary
- Amboina Sailfin Lizards are incredibly strong swimmers, uniquely adapted for a semi-aquatic life with specialized fringes on their toes that allow them to run briefly across the water's surface. They are inherently skittish and will readily plunge into the nearest water body at the first sign of a threat, using their massive sail-like tails for rapid aquatic propulsion. While they bask frequently on branches overhanging the water, their impressive size and territorial nature require vast enclosures in captivity.
- Reprodução
- Oviparous
- These large lizards reproduce by laying eggs, a process typically occurring in the soft, sandy banks of the rivers they inhabit. Females carefully excavate deep nesting chambers to ensure the eggs are protected from predators and kept at a stable, warm temperature. The hatchlings must navigate the treacherous riverbanks from the moment they emerge, immediately putting their innate swimming skills to the test.
- Tolerância de tratamento
- Expert only
- They are powerful, fast, and equipped with sharp claws. They require an experienced keeper, as they can be flighty and difficult to tame.
- Brumação
- Não obrigatório
- No brumation is required. They need high basking temperatures and warm water year-round.
- Muda
- Periodic
- Shedding occurs in patches. Having access to a large pool of water allows them to soak and soften old skin, facilitating a clean molt.
