The common basilisk can be distinguished from similar species within its range by its large size and the high fin-like crests down its back. Males also have high crests on their heads and tails. Both sexes are brown to olive, and have a white, cream or yellow stripe on the upper lip and a second stripe along either side of their bodies; these stripes have higher contrast in juveniles and fade as the lizards age. Adults can grow up to two and a half feet long. They have been known to run up to 7 mph (11 km/h). While the basilisk is most known for its ability to run on water, it is also an excellent climber and swimmer; the basilisk has been known to stay under water for up to half an hour.
