Species overview
About the Mangrove Tree Boa
The mangrove tree boa has a long climbing body and a tail that can help grip branches. Brown and tan patterns blend with bark and shadow. It is not the bright green emerald tree boa shown in many South American wildlife pictures.
In Costa Rica its range is southwestern. The common name does not mean it lives only in mangroves; suitable wooded habitats provide branches and cover too. Watch its resting position from a distance. Never pull a snake from a branch or shake the vegetation to make it move.

Conservation & care
Observe from a distance with an adult or qualified guide. Do not touch, catch, corner, feed or move any snake. Keep children and pets away. Colors, head shape and pupil shape must never be used to decide a snake is safe.
