FAQ
Frequently Asked Questions
No. It is a lizard that shares some physical and behavioural similarities with caimans, such as a heavily scaled back and an aquatic lifestyle, but it is not a crocodilian.
Its diet is highly specialised, consisting mainly of aquatic snails and other molluscs, which it crushes with its strong, rounded teeth.
They are kept by experienced reptile hobbyists but require complex, large aquatic setups, specific humidity and temperature, and a specialised diet, making them challenging pets.
They are most commonly seen in specialised reptile zoos, aquariums with rainforest exhibits, or in their native habitats in countries like Brazil, Peru, and Ecuador.
