The Jesus Lizard
When fleeing from predators, this reptile runs along the surface of water such as a pond or stream. The lizard reaches about 5 miles per hour this way. It propels itself along the water, using surface tension to briefly support its weight. The lizard’s toes have flaps of skin to create a broader surface and an air pocket to enhance the surface tension. But the “miracle” soon gives way to physics and the lizard is forced to swim.
