Echolocation calls are usually ultrasonic--ranging in frequency from 20 to 200 kilohertz (kHz), whereas human hearing normally tops out at around 20 kHz. Even so, we can hear echolocation clicks from some bats, such as the Spotted bat(Euderma maculatum). These noises resemble the sounds made...

Bats utilize a system of sonar to locate objects as they fly and prey. This system of echolocation is not only used by bats but also whales, dolphins,... Learn more about this topic: Echolocation Definition, Uses & Examples from Chapter 5/ Lesson 1 ...
Some of these hunters have developedecholocationabilities to help them find their prey and locate any obstacles. Echolocation is a very simple concept: The whale emits a series of clicks (or other sounds) from its mouth or from organs in its head, and the sound waves travel out in the surr...
They are more closely related to shrews or primates. Though bats often get a bad reputation, they are not aggressive, and are often very beneficial in eliminating pesky insects. Bats aren't blind. They can see just fine, but they also use echolocation as their means of navigating complex ...
The reflection of sound is used by some animals, notablybats, for echolocation — locating, and in some cases identifying, objects through the sense of hearing rather than the sense of sight. Bats emit bursts of sound of frequencies far beyond the upper limits of human hearing. Sounds with ...

While toothed whales practice echolocation, or emitting high frequency sounds to find objects, baleen whales make sounds at much lower frequencies that resemble moans and belches. Because baleen whales have a good sense of hearing, it's possible they're communicating with whales hundreds of kilo...
