How do bats use echoes?
Answers
Answer:
echolocation
Explanation: Echolocation is a technique used by bats, dolphins and other animals to determine the location of objects using reflected sound. This allows the animals to move around in pitch darkness, so they can navigate, hunt, identify friends and enemies, and avoid obstacles.
Bats, whales, dolphins, a few birds like the nocturnal oilbird and some swiftlets, some shrews and the similar tenrec from Madagascar are all known to echolocate. Another possible candidate is the hedgehog, and incredibly some blind people have also developed the ability to echolocate. Bats make echolocating sounds in their larynxes and emit them through their mouths. Fortunately, most are too high-pitched for humans to hear – some bats can scream at up to 140 decibels, as loud as a jet engine 30m away.
