Which lizard can run on water to escape predators?

The basilisk lizard can run across water to escape predators. Often nicknamed the “Jesus Christ lizard,” it sprints upright on its hind legs and can cross a short stretch of water before sinking and swimming away.

Its unusual ability comes from a combination of speed, foot shape, and technique. Basilisks have long toes with flaps of skin that spread when the foot strikes the surface, trapping air and increasing the area pushing against the water. Rapidly slapping and withdrawing the feet keeps the lizard above the surface for a few seconds.

Young basilisks are especially effective water-runners because they are lighter; adults usually manage only several metres before their weight breaks through the surface. The common basilisk is native to parts of Central America and spends much of its time near streams, rivers, and ponds.

A common mix-up is that basilisks do not literally walk slowly on water. They run at high speed, usually when startled, and other lizards—including some sailfin lizards and anoles—can also show water-running behavior.
