Emerald Tree Boa (Corallus caninus, Hundskopfboa)

The Emerald Tree Boa (Corallus caninus) is a non venomous species of bright green snake that lives in the rainforests of South America.


Emerald tree boas are typically a shade of emerald green in color with a white irregular zigzag stripe down the back and a yellow underside. The bright coloration and markings are very distinctive among South American snakes. Juveniles are extremely variable in color, and are often orange or yellow, with irregular spotting.


Emerald tree boas have many morphological differences based on locality, enough that some herpetologists have considered whether they should be classified as subspecies. Specimens from the Amazon River basin tend to grow the largest, attaining lengths of 7-9 feet (2.1-2.7 m), while the overall average size is closer to 6 feet (1.8 m). Emerald tree boas from the southern end of their range in Peru tend to be darker in color.


It appears very similar to the green tree python (Morelia viridis), from southeast Asia and Australia, but they are only very distantly related, and are an example of convergent evolution. Physical differences include the scales on its head, and the location of the heat pits around the mouth in the boa.


The young snakes are born living, as with most boas (whereas pythons use to lay down eggs).


An easy to photograph snake because it does not move very often but stays in this typical position on her branch. By the way: those boas do not leave their tree for their whole life as long as some frogs (food) cross their way sometimes ...
