The green tree python art (unframed) was done on an 8"x12" piece canvas in black paint. The Reptile Discovery Center's own artistic keeper Robin came up with a cool idea with a green tree python print and black paint, you get an awesome inverse effect, almost x-ray like with a splash of color. Green tree pythons are tree-dwelling snakes that are found in New Guinea and the islands of Indonesia. They have heat sensing pits to detect the location of their prey which mainly consists of birds and bats coming in to rest for the night.
