Bats use echo location, they track down sounds of prey by their sound waves.
No only bats use echolocation
Echo Location really is the answer
It doesn't, that is why they use echo location.
echo location tells them where things are.
Echo location via high frequency sound
Bats use echo-location to avoid obstacles and to hunt their flying prey.
Generally they fly, occasionally they glide. They also use Echo-Location like all other bats.
Sight! Their eye-sight is quite good, but they augment this with echo-location for navigating and hunting in low light, and use echo-location entirely for navigating in the absolute darkness of caves or mines.
Bats have a very good sense of hearing since they are blind. They use echo location to determine where to go without getting into trouble.
Echo location, also called SONAR. This is just like the pinging you hear in a submarine movie
No, except that the Egyptian Fruit Bat uses high pitch clicking in caves.
