The Aquarium is currently open to the public. In response to COVID-19, we’ve made some essential changes to ensure a safe and enjoyable experience for all.

Emerald Tree Boa

(Corallus caninus)

Overview

Emerald tree boas are non-venomous, arboreal snakes. They use their prehensile tail to hold onto tree branches. Their head rests atop their coiled body during the day; at night, they hunt for birds but may also eat small reptiles and mammals. Adult emerald tree boas are a bright green color with paler yellow or white bellies, and some have striking white marks along their backs. As juveniles, these snakes are yellow, orange or red.

A Note From the Caretaker

Because the emerald tree boa is nocturnal, most Aquarium guests see it coiled quietly on a branch. At night, though, the snake wakes up and moves along the branches and vines in its habitat.
