So high that we can't hear it.
No, except that the Egyptian Fruit Bat uses high pitch clicking in caves.
Echo location via high frequency sound
------------------------------------------------------- Bats use a type of "sonar" to locate objects even in the dark (echo-location). A bat makes a high-pitched noise that bounces off objects nearby and the bat hears the echo. By timing how long it takes for the bat to hear the echo, it can calculate how far away it is. When it comes to a flying insect, the bat listens to the echo of it's noises and is able to locate where an insect is. Then it can fly to the insect and catch it - even if it is pitch dark. They use echo location. It is tiny beeps, too high pitched for our ears, and dogs ears too! The bats let out the tiny beeps, and the echoes tell them where bugs are.
Through echo-location. They emit high-pitched sounds and by listening to the echos they get a kind of radar picture of their surroundings.
Ultra sonic sound, I could be wrong. It could also be echo location.
They do not see infrared light. Most bats are completely blind, using 'echo-location', ie radar, to "see" in the dark.

Their echolocation consists of tiny beeps, too high-pitched for our ears, and the echoes tell them where bugs are. Bats are not actually blind! Bats can actually see very well but at night they use echolocation. This process enables bats to emit sounds from their mouths that bounce off objects and allow them to avoid the objects when flying.
Yes, bats can use echolocation to find their food. They emit a high squeal and listen for the echo to find things in the dark.
They emit a series of high pitched squeaks and react to the echo that comes back from nearby objects.
Bats do have eyes. They hunt at night so eyes are of limited use. Instead, they find their prey by echo location. They emit high pitched squeaks and listen to the echoes which come back to work out where things are.
Probably whales, perhaps elephants. Both are known to produce sounds too low in frequency for humans to hear. In fact, there is a common phenomenon that people experience at elephant exhibits it zoos that is described as a vibration in the belly that is caused by the sounds that elephants make.
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.
