This is called echolocation.

Bats

Bats can also use echoes to tell the direction an item is moving.

Whales and Dolphins

Marine mammals including whales and dolphins additionally use echolocation to discover things at lengthy distances, past the range of vision, and also within the depths of the ocean where it’s far very darkish. Whales use echolocation for navigation and to find food. Dolphins additionally emit clicks with their nasal tissue and use the echoes to locate their manner round and to hunt. They additionally use echolocation to talk with other members of their group and to avoid predators.

Oilbirds and Swiftlets

Echolocation is rare among birds. Two species of birds that stay in caves and are known to have evolved echolocation are South American oilbirds and swiftlets. Oilbirds emit clicks and use the echoes to help they navigate in overall darkness. Swiftlets use echolocation for navigation in the dark and additionally for social purposes.

They discover their way thru leaf litter or in the darkness of tunnels beneath snow with the help of echoes produced by sounds they emit.

Humans

Sonars and radars, used by people for navigation and to discover objects, are styles of echolocation. In fact, the development of those technologies was inspired by the paintings of zoologist Donald Griffin who found how bats navigate and coined the term “echolocation.” Some blind human beings have developed the potential to find obstacles by way of making clicking sounds with their tongues and listening for echoes. A new take a look at indicates that blind those who can echolocate really use the visual parts of their brains.
