Vernacular names
English: Tree Boas

Corallus is a genus of non-venomous boas found in Central America, South America and the West Indies. Seven species are currently recognized.[2]


All members of this genus are long, slightly flattened laterally and have thin bodies with large heads. They typically have relatively large eyes, although this is less pronounced in the larger species, such as the emerald tree boa, Corallus caninus. The anterior teeth are highly elongated, often being several times the length one would expect for snakes of their size. These are used for penetrating layers of feathers to get a firm grip on birds, their primary prey. All members of the genus are nocturnal and have large numbers of very pronounced thermoreceptive pits are located between the labial scales.

T) Type species.


Two species are frequently imported as display animals, the Amazon tree boa, C. hortulanus, and the emerald tree boa, C. caninus. "Pet" is not a term one would apply to these species, as most, if not all, have an aggressive demeanor and will strike readily. Their stunning coloration makes them popular, but their specialized habitat and feeding make them suitable only for advanced keepers.
