What is Echolocation?
[[File:Animal echolocation.svg|thumb|right|300px|The ultrasound signals emitted by a bat, and the echo from a nearby object]] '''Echolocation''' is a way that some animals use to determine the location of things. They emit sound waves and listen for the echo. They use the delay to determine the distance. It is a kind of biological [[sonar]]. [[Microbat]]s find their [[insect]] [[prey]] in the dark this way. [[Whale]]s and [[dolphin]]s are two other kinds of [[mammal]]s that use echolocation. Their sound waves go through the water, while the bats' sound waves go through the [[air]].<ref> {{cite book |title= Magic School Bus: the truth about bats|last= Cole|first= Joanne |author2= Bruce Degen|year= 2001|publisher= Scholastic Inc.|location= United States of America|isbn= 0-439-31432-1|pages= 13}}</ref> [[Radar]] is man-made echolocation using [[radio wave]]s. == References == {{reflist}} {{-}} {{biology-stub}} [[Category:Hearing]]
