Emerald tree boas are so named because of the exquisite green coloration on their dorsal surfaces. Many populations have striking white markings occurring along the dorsal midline, although some individuals lack them. Other individuals have black coloration on the dorsum. Juveniles range from a brown to red color. They can grow to be over 5 ft. in length. Male emerald tree boas are usually smaller in size and have larger spurs. It is believed that they can live well over 20 years, though little data is available, especially in the wild.
Diet in the Zoo: Generally mice.
Diet in the Wild: Nocturnal predators of rodents and other small mammals, lizards and birds.
Emerald Tree Boas typically breed from late January to July with gestation period of 5 to 7 months. Research is scarce on reproduction.
During the day they remain inactive, looped over a horizontal branch. They form an ellipsoidal coil with their bodies, with the head in the center. As ambush predators, they catch most prey by snatching them off the ground as they hang from these branches.
The IUCN does not list this species as threatened. They appear to be abundant throughout much of their habitat.
