Echolocation is also a bio sonar for seven kinds of Animals. It is when animals like Bats locate objects that are around them or near them. Underwater animals use echolocation, their soundwaves go through water. Bats sound waves go through the air just like humans. Lots of Animals use Echolocation to catch their prey or obstacles when its dark.
Bats use echolocation when they give out sound waves either using their mouth or nose. When the sound waves hit an object their sound waves reflect back to them. At that, the bats know what or where it is. They know the size, sound and shape and texture of the object. Even a tiny insect just from its echo!
