Fun Fact(s):
Also called Green-Crested Basilisk, Double-Crested Basilisk, & Jesus Christ Lizards. Called latter due to ability to run on water. If predator finds them in tree, they can drop into water below, quickly running across surface to safety. To do this, they have special toes on rear feet w/ fringes of skinlike scales spreading out in water increasing surface area of foot making contact w/ water. Can run 5 ft/sec for 15-20 ft before sinking on all 4s & swimming. Can also sustain themselves on all 4s while “water-walking” increasing distance traveled above surface by 4.3 ft.
When running on water, they pump legs rapidly, slapping feet against water. They’re also excellent swimmers & can remain submerged for up to 30 minutes.
Gets basilisk name from legendary reptilian creature said to turn humans into stone by gaze. Basilisk said to be half-reptilian/half-rooster & males have noticeable rooster-like features. Word originates from Ancient Greek word meaning “little king/little prince.” Even today, some native tribes believe these lizards have magical powers.
