Brown Basilisk

The male brown basilisk can reach 61 centimetres (24 in) in total length (including tail), but the female is somewhat smaller. It has a three-part dorsal crest on the head, along the back, and along the tail. Coloration is brown or olive brown with black crossbands. The crossbands are usually only on the flanks and on the dorsal crest. There is also a white stripe, which extends from the eyes to the rear legs. The male has a larger crest than the female. The brown basilisk weighs 200–600 g (0.44–1.32 lb). It has long toes with sharp claws.

Basiliscus vittatus is in the same infraorder as the family Iguanidae. Like most reptiles, the brown basilisk is active during the day. Its outstanding camouflage allows it to remain motionless and very hard to detect. The maximum lifespan of the brown basilisk is probably around 7–8 years. In the wild, most die much sooner.

The brown basilisk's generic name Basiliscus is taken from the creature of Greek mythology made up of parts of a rooster, snake, and lion that could turn a man to stone by its gaze: the basilisk. This name derives from the Greek basilískos (βασιλίσκος) meaning "little king". This generic name was given in Carl Linnaeus' 10th edition of Systema Naturae.
