Are bats really blind?

BatIn reality, all bats can see. Many of the bats, in fact, can see really well, even in the dimmest of light. Most fruit-eating bats have large bulging eyes that help them find their way and locate food by sight.

But other bats, especially those who are hunting for insects at night, need to rely a lot more on other senses in the dark. These animals make up for low visibility by “seeing” with their ears, and they do this by using a technique called echolocation. A bat uses echolocation by sending out streams of high-pitched sounds through its mouth or nose. These signals then bounce off nearby objects and send back echoes, determining the location, distance, size, shape, and texture of an object in its environment.
