Corallus, the neotropical tree boas, are a genus of boas found in Central America, South America and the West Indies. Nine extant species are recognized .
==Description== 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.
