What do rabbits uses their ears for?

Answer 1

There is no actual reason for the size of their ears. It is just one of their adaptations.

that was not the answer i was looking for

The reason why the rabbits ears are so large is because they have had to adapt to their environment in the wild, as they are a prey animal, and have many predators, they have had to adapt to be able to 'tell' when an predator is in the vicinity.

The rabbits ears are large, which enables them to catch the sound waves more effectively, and hear the sounds in the environment more clearly. they are able to hear predators and humans approach from a distance, and are also able to use their keen sense of smell to tell where and how near a animal or predator is, they are also able to tell the difference between male and female humans from their scent.

Rabbits also use their ears as a temperature control mechanism, to warm themselves up or cool themselves down, they are able to do this because their ears are filled with blood vessels which run close to the surface of the ear. When the animal is too hot the blood vessels are able to cool the blood down from the cool air around the ear, the blood vessels are also able to warm the blood by the ears being in the sun, warming the ears and in turn the animal..... hope this helps :)
