How can basilisk lizards run across water?

Basilisk lizards, often called "Jesus Christ" lizards, are able to run across water for short distances by utilizing their high speed, light body weight, and specialized anatomy.12

When frightened, these lizards sprint across the surface on their hind legs. To prevent sinking, they rely on broadscale fringes on their toes, which increase surface area and provide the necessary support against the water. During this bipedal locomotion, the lizard’s long, whiplike tail is held backward and upward to act as a counterweight, helping the animal maintain balance while it moves. While both juveniles and adults possess these traits, it is typically the younger, lighter individuals that are most frequently observed successfully running across the water's surface.12
