Green tree pythons, scientific name Morelia viridis, are an arboreal (tree-dwelling) python. They have slim bodies, long tails, and large, muscular heads. Green tree python color ‘morphs’ vary based on their locality.

The most common type of green tree python in the U.S. is the Biak. They have vivid green bodies, interspersed with asymmetrical yellow splotches. Another favorite is Aru. These pythons have blue blotches along their backs and scattered clusters of white scales.

You may have heard green tree pythons referred to as “chondros.” This is a name stemming from their original taxonomic name, which used to be Chondropython viridis. Some breeders have begun to delve into the world of “designer” green tree pythons, but they’re still uncommon.
