Emerald tree boa. Head of a yellow juvenile emerald tree boa (Corallus caninus). Its green colouration develops as it matures. This snake lives in the trees of the Amazon Basin of South America. It mainly feeds on lizards and birds which it catches in its mouth before constricting them in its coils. The deep pits along its jawline are thought to detect infrared radiation, helping it hunt in the dark.
