The reasons for the lizard walking on water for short distances are actually none of those suggested. There follows some modified extracts from articles that I have found. For more information try using Google and typing in "Jesus lizard walking on water" The Basilisk Lizard, nicknamed the 'Jesus Christ' Lizard, has the amazing ability to be able to walk upon the water.
It can run up to one hundred feet across any body of water. The Basilisk goes into the water, and using it's feet, pushes down, creating a cavity almost like an air bubble. Bulky lizards, he says, generate less supporting force, relative to their body size. This is why we could never emulate a basilisk. Using the same mechanism, an kilogram human would have to run at kilometres per hour and generate a power output of 15 times the maximum output sustained by someone running uphill.
But scientists have figured out how so-called Jesus lizards are able to scurry across the surfaces of ponds and streams. The findings improve understanding of the physics involved in walking in general and may have practical use in the development of walking robots.
The Jesus lizards, or basilisk lisards, accomplish the seemingly miraculous act of moving on top of water by generating forces with their feet that keep their bodies both above the surface and upright, according to Shi-Tong Tonia Hsieh. Hsieh and her advisor George Lauder detail the process in today's issue of the journal Proceedings of the National Academy of Sciences. The finding challenges established rules for the mechanics of legged locomotion, which are mostly known from studies of how animals walk across solid surfaces in a laboratory setting, Hsieh said.
Without knowing much more, we'd think there's some sort of continuum in the strategy animals use to move across surfaces," she said. Robert Full, a professor of integrative biology at the University of California, Berkeley, and expert on animal locomotion, said the lack of answers to such questions is holding up the development of new technologies. To find answers, Hsieh and Lauder turned to the basilisk lizard Basiliscus plumifrons , a skittish tree-dwelling species found in Central America.
When frightened by a predator's approach the lizard will drop to the water and run across the surface. The lizards range in size from less than 0. Throughout their size range, they can run across water on their hind limbs at about 5 feet 1.
The lizard is often called the Jesus Christ lizard in Central America because of its seeming ability to walk on water. Most animals that attempt to walk—or run—across water immediately sink toward their supporting limb because water, unlike solid ground, offers little support or resistance.
To understand how the Jesus lizards move across the surface of the water without tipping over, Hsieh and Lauder filmed them with a high-speed video camera as they ran across a water tank. The water was sprinkled with tiny, reflective glass beads that sparkle when lit. Using computer software, the researchers are able to overlay adjacent video frames to see how the beads move. This allowed them to calculate the forces generated throughout the lizards' stride.
The stride is divided into three phases: the slap, the stroke, and the recovery. We completely agree. Andi May 8, May 9, We're thrilled that you found this Wonder interesting, Andi!

Jaxson Nov 20, I love lizards so this was really good for me.
Thanks for sharing, Jaxson!! Nov 19, Very interesting! Basilisk lizards are amazing creatures! Komodo Dragon Nov 9, Im a dragon But i can't fly, but i can run on water like the basilisk lizard. Nov 15, Nov 13, Tom Nov 13, Aidan Nov 9, Nov 12, GOAT Nov 9, We hope you have a good disguise!
We're glad you liked it, memphis! Jacob Nov 9, Cloud the Dinosaur King Nov 9,
