Geckos are known for their acrobatic feats on land and in the air, but a new study reveals that they can move with water.
Robert Pullen, professor of integrative biology at the University of California, Berkeley, is the lead author of the study, published on December 6, 2018 in the journal " Current biology Full said in a statement:
They can climb a wall a meter in a second, slide, stand out in the air with a twist of their tail, and quickly turn around under a sheet of full speed. And now they can work per meter above the water. Nothing else can do that; geckos are superheroes.
The teams studied short-haired geckos, commonly found in South and Southeast Asia. In the lab, the research team built a long water reservoir, put the gossies on a board and startled them by touching their tails. Using a high-speed video, they were able to study gecko techniques in detail and evaluate the forces involved.
They found that the geckos were able to work almost a meter (3 feet) per second above the water, and easily passed over speed over a solid surface or climb a vertical surface. Researchers claim that the geckos sprinkling on the surface of the water exceed the absolute velocity of swimming of much larger aquatic professionals, including ducks, minks, musks, sea ligans and juvenile alligators, and are faster at a relative speed than any recorded a swimmer other than beetles,
Smaller animals, such as spiders, beetles, and beetles, for example, are light enough to be kept on the surface, researchers said, allowing them to easily glide on the surface. Larger animals, such as swans during takeoff or lizard, and even the dolphins that rise in their queue, hit quickly and hit the water to hold onto the waves. Fully said:
Larger animals can not use surface tension, so they eventually push and hit the surface that creates power if you make it hard enough.
But the gecko has an intermediate size: about 6 grams (1/5 of an ounce or weight of paper) they are too large to float above the surface but too light to keep their bodies above the water just the clapping forces.
