Fascinating Facts

• Emerald tree boas were given the scientific name “caninus” due to their dog-like appearance in profile.
• Emerald tree boas have large heat sensors with which they can sense infrared radiation and detect prey.
• They have a prehensile tail, which they use to secure themselves in a tree, in their distinctive coiled pose.
• They have sharp teeth, which pierce prey and they will then coil around prey to constrict and kill it.

Babies are reddish or orangish in color when born, turning their distinctive emerald shade between six months and a year.
