Description

Green basilisks are bright green with small bluish spots along the dorsal ridge. These lizards may grow up to 3 ft (1 m) in length (most of which is tail), with an average length of about 2 ft (0.6 m). Males have three crests: one on the head, one on their back, and one on the tail. The females, however, only have one crest, on the head.
