Bats Section-
-most all bats use echolocation to navigate through the night in order to find prey and their own habitat
-sounds are produced by either the mouth or nose
-bats can emit sounds at very high decibels, but because of the high frequency of the emission humans are unable to hear them
Birds Section--Two types of birds use echolocation: Swiftlets and Oilbirds
-Clicks originate in the Syrinx
-Echolocation they use is elementary because it can be heard by humans-Use echolocation to find nests/ ways back to their "home"
Dolphins and Whales Section-
-Produce sounds by moving air between air-spaces or sinuses in the head.
-Sounds are echoed back from objects, and are thought to be received by an oil filled channel in the lower jaw and conducted to the middle ear of the animal.
-Toothed whales and dolphins use echolocation for hunting and navigating
-Baleen whales produce a series of sounds which are termed 'songs' that are used for communicating.
Shrew Section-
-There are only three known types of shrews that utilize echolocation: Vagrant, Eurasian, and Northern-short tailed shrew
-Ecolocation for orientation instead of hunting or communication
-There is still research occurring to determine what their echolocation is used for
Moths Section-
- A female Tiger moth lays 50 - 100 eggs per lay, and several generations can occur in one year
- Sonar clicking frequencies evolved as a defense mechanism to the moths
- The moth sonar jams the frequency of the bats returning sonar which confuses the bat
