Discover what echolocation is, why it evolved and which animals use it, as well as exactly how bats, dolphins, whales and other animals use echolocation.
To help them find their prey in the dark, most bat species have developed a remarkable navigation system calledecholocation. To understand how echolocation works, imagine an "echo canyon." If you stand on the edge of a canyon and shout "hello," you'll hear your own voice coming back to ...
Bats aren't blind. They can see just fine, but they also use echolocation as their means of navigating complex flight and finding insects on the wing. A bat's wings are essentially the same as our arms and hands, thus the scientific name Chiroptera or handwing. The bones of the hand ...
“When people echolocate, it’s not like now they can see again. But echolocation does provide information about the space that’s around people, and that would otherwise not be available without vision. It allows them to orient themselves and so on,” says Lore Thaler, lead author of the...
sense of sight. Bats emit bursts of sound of frequencies far beyond the upper limits of human hearing. Sounds with short wavelengths are reflected even from very small objects. A bat can unerringly locate and catch even a mosquito in total darkness. Sonar is an artificial form ofecholocation....
Ultrasound works similarly to bats echolocation. It uses high frequency sound waves that capture live images from inside the body. This works like how a bat can see with soundwaves but be almost blind. The next person Karl Dussik, physicist was the first doctor to use ultrasound as an ...

A bat can unerringly locate and catch even a mosquito in total darkness. Sonar is an artificial form of echolocation. Refraction When a wave passes from one material to another at an angle, it usually changes speed, causing the wave front to bend. The refraction of sound can be ...
Interestingly, the first big jump in whale brain size seems to have happened when cetaceans first started using echolocation, the ability to locate objects with sound. The narwhal swims through deep waters in search of its prey, and as you might imagine, it's a bit murky down there. Bats,...
You may not think a bat is a mammal, but it is! Bats are, in fact, the only freely flying mammal. Bats use echolocation to allow them to “see” in the dark. They let out a high pitch sound and it bounces off objects, then the sound returns, providing them with all sorts of in...
