This is an arboreal (tree-dwelling) pitviper confined to the mountainous regions of Costa Rica and Panama. Arboreal adaptations include its green color (great for camouflage!) and a prehensile tail that can grasp tree branches.

As a group, the palm-pitvipers tend to have isolated and fragmented populations in the mountains of Central America. The effects of habitat destruction and natural disasters make them vulnerable to extinction. Herpetologists fear that several species of palm-pitvipers may already be extinct.
