Using echoes for detection of objects is known as echolocation and can be observed with bats and other creatures. It is also referred to as biosonar. In this book, you will be learning about how it works as well as how it is used by natural creatures as well as by humans.
Echolocating animals send out calls to their environment and then listen for the echoes of calls that return from any object that is near them. These echoes are then used for locating and identifying the objects. It is also used for hunting (foraging) as well as navigation in different environments.

Animals that utilize echolocating include a few birds and some mammals, but most notable are the toothed whales and dolphins (odontocetes) and microchiropteran bats. There are also other groups that utilize echolocating in simpler forms, including shrews.
What is Echolocation?
Using echoes and sound waves to determine where an object is located is known as echolocation. Bats are known to use echolocation for finding food and navigating in the dark. Bats send out the sound waves using either their nose or mouth.
