Watch Hikers Racing on Water! | Earth


<! –


Geckos is known for its acrobatic feats on land and in the air, but a new study reveals that they can also work on water.

Robert Paul, a professor of integrative biology at the University of California, Berkeley is the senior author of the study, published on December 6, 2018, in a review journal Current biology Completely stated in the statement:

They can operate to a wall with a meter per second, can fly, can be positioned themselves in the air by twisting their tail and quickly inverted under a sheet that runs at full speed. And now they can work per meter per second through water. Nothing else can do it; lizards are superheroes.

The teams studied the hectones with a flat island, common in South and Southeast Asia. In the laboratory, the research team built a long water tank, put the lizards on the plank, and strangled them by touching their tails. Using high-speed videos, they could carefully study hex techniques and evaluate the forces involved.

They found that lizards were able to move at nearly one meter (3 feet) per second through water, and easily transferred to acceleration through a solid foundation or climb to a vertical surface. The researchers say the spray of lizards on the surface of the water exceeds the absolute floating velocities of much larger aquatic specialists, including ducks, noons, slippers, marine iguans and juvenile alligators and are faster at relative speeds than any floating surface swimmer.

The study describes four separate strategies that the geeks use to scroll over the surface of the water: planning, as a speed boat; support from surface tension; slapping and dragging the water; and a tail lift. Photos via PolyPEDAL Lab Graphic, UC Berkeley

For example, smaller animals like insects-spiders, bugs, and water-are light enough to maintain surface tension, researchers say, allowing them to easily move along the surface. Larger animals, such as swans during a take-off or a basilica lizard, and even dolphins lifted on their tails, quickly slap and stroke to overcome the waves. Completely said:

Larger animals can not use surface tension, so they end up pushing and slipping on the surface, which creates strength if you do it hard enough.

But gecko is of medium size: about 6 grams (1/5 of an ounce or weight on a piece of paper), they are too large to float above the surface, but too much light to hold their bodies over the water just spit forces.

Animals use different techniques to stay above water. Larger animals, mainly insects, are supported only by surface tension. Severe animals can produce enough strength with their feet or tails to stay above the water. But lizards are interconnected, using both techniques. Photos via PolyPEDAL Lab Graphic, UC Berkeley

Bottom line: The video shows lizards working on water.
