|Ruschenberg's treeboa from the Frenchman's River, Tobago. JCM|
The longest of the nine treeboa species is Ruschenberg's treeboa, but it has less bulk than three of the other species (batesii, canius, cropanii) based on body girths. Ruschenberg's treeboa has a large distribution, ranging from Costa Rica to Venezuela, and it occurs on Trinidad, Tobago, and the Isla de Margarita. The authors found it feeds on lizards, birds, marsupials, rodents and carnivores (mongoose).
