ultrasonic
It is an audio form of radar - the ability to tell the size and distance of object by listening to the echoes they produce. Bats use it in the air. Dolphins, porpoises and whales use it under water.
They HEAR using their ears but they use the echoes of the sounds they make to build a "sound picture" of their surroundings. This is used to avoid collisions and to catch prey. This use of sound and echoes is called "echo location".
The bat uses their echoes of their cries to know where the prey is.
Bats, dolphins, Whales, shrews, flying squirrels use echolocation.
Bats and toothed whales (dolphins, porpoises, killer whales, sperm whales, and river dolphins).
they let a high pitched sound out of their mouth and it echo's back if it's hit's something if not it keep moving until i does Many types of bats as well as aquatic mammals such as whales and dolphins regularly use echo-location to find food and find their bearings.

No, but bats do, some whales, birds and rodents, too.
The three animals I know that haveecho location are Dolphins, Hammer Head Sharks and Bats. Mostly use to navigate and search for food. new ans: for example: Bat's eyesight are not perfect. they will send out sounds and if the sound does not bounce back,it means the road ahead is clear. but if the sound bounces back,it means an object is in front and the bat will change the direction and try again. T here was a test done on Hammer Head sharks, since their eyes are on the side of there heads. Because of that they have a sonar under their head. And they use echo location. They look for food and animals under the sand.
He could hear echoes throughout the mountain range.
