to hear their surroundings. dur use ur common sense. -.-
In the wild, the ears help them listen for predators and other dangers. For a pet, they don't matter much.
echo location tells them where things are.
It help it survive by sensing every sound around it. Bats use hearing and echolocation to locate objects and tell their way around. Without its hearing, it would not be able to detect its surroundings.
Animals use their ears to hear sounds in their environment, communicate with each other, and detect potential dangers. Ears also help animals maintain balance and orient themselves. Some animals, like bats, use their ears for echolocation to navigate and find prey.
i think the uestion you are asking is what do bats use their ears for. well the use there ears to sonicly see where they are going. the use is for hearing the massive screecth noises. and by the time the sound comes back it basicly makes a 3D image of its surroundings.
the ears
yes they use their ears to radiate body heat.
Bats have large ears to enhance their hearing abilities. Their ears are adapted to pick up high-frequency sounds which help them navigate in the dark and locate prey using echolocation. The large surface area of their ears allows them to capture more sound waves, giving them a competitive advantage in hunting and avoiding predators.
Echo Location really is the answer
Some bats use their ears to have sonar vison which lets them move in the dark without using their eyes.
kinda they use their eyes a bit for hunting but mostly they "see" with their ears.
Ears help rabbits to hear, of course! (But if it is arctic hare, even though it may hear better, it does not keep warmth inside.) Rabbits also use their ears to communicate with. They can move them backwards and forwards, lock them to the side, and they can rotate them so that the openings face one way or another -- the different positions mean different things to other rabbits.
