Watch -- mandatory gliding through the water it moves so we easily you may think it's disgraceful or for that matter scary because of -- -- But it's also there we -- in the fish. Now watch this back -- right. It moves much the same way except the color is wrong and extremely capable this one is a robot being tested in the pool at the University of Virginia. Researchers are trying something -- I -- in the court they figure nature got something right but it created an Angel is so they're trying to copy. We have a very unique propulsion mechanism that's not. Seen in Britain and any other types of underwater species -- -- trying to understand. How with a swim and why -- -- when -- -- do so that we can apply that knowledge in the development of underwater autonomous vehicle. A mechanical relays swimming on its own could be used to patrol the ocean water and -- -- pollution. -- -- could be used as a weapon silently carrying explosives. A couple of the really practical reasons why would be interested in -- to -- either efficiency of speeds. And then maneuvered. It's you know understanding of science basically allows us to ticket fine -- -- -- nature has already. -- and there's still a lot of work to be done but researchers see they have been for Warren. -- -- mechanical Mediterranean. And given the right coloring and then look so realistic. The sharks were wanting heat. The potter ABC news New York.
