They can hear high-frequency sounds that the bats make continually while flying . Bats can determine the direction and distance of objects in the area.This is called echolocation, each species of bat uses echolocation to make its own kind of noises.
Echo location via high frequency sound
They do not see infrared light. Most bats are completely blind, using 'echo-location', ie radar, to "see" in the dark.
They used the stars to navigate by using the north star
they were smart
They use ultrasound. They emit high-pitched 'squeaks' which are reflected off objects close to them - and the sound is picked up by their ears. The minute differences in the sound volume in each ear - tells the bat where the object is.
They emit a sound that bounces off surroundings and makes it's way back to the bat. It can then navigate itself around trees, other animals, and etc.
the bats
Echolocation
No one is able to hear ultrasound; the frequency of the sound used is far higher than the audible limit of any person or animal. A sonographer will conduct an ultrasound. Ultrasound in the same way that bats navigate - by listening to echos. ultrasound is reflected in propotion to the density of soft tissues. an ultrasound displays the results of these echos.
To navigate because they can't see. They send out high frequency signals which bounce off walls and see how long it take to come back in simple terms. They can also use it to find prey such as moths.
Bats and Dolphins both use sound to navigate.
There are many animals that use ultrasound. Some of these anmimals include; cats, dogs, dolphins, mice, fish and whales. the can use it to detect their prey
they use sound to navigate and FIND there food but not to actually get the food, theyll use there eyes for grabbing berries or animals
sound radiation
There put their butts in the air
They use echolocation (a form of ultrasonic ranging) to locate their food.
Smaller animals use sounds of shorter waves - bats live only due to ultrtasonic wav es - while whales are said to communicate in very long sound waves. It is interesting indeed - is there an animal who perceive both?
