Listening.
Rabbits use there whiskers to make sure they can fit threw small spaces. Not only do rabbits use their ears to hear, they move them around to communicate with each other.
The plural form for rabbit ears is (one) rabbit's ears; or (two) rabbits' ears.
rabbits and bunnies use their ears to listen to predators.
True
It's not true that rabbits with long ears have a longer lifespan than rabbits with short ears. Ear length has no bearing on a rabbit's lifespan.
It depends on its species and size. Tiny rabbits have tiny ears.
no rabbits ears are very sensitive and they use them very readily for hearing and picking them up by the ears can harm their hearing
There are many rabbits with ears sticking up. My Netherland dwarf rabbit, which is the smallest rabbit, has upright ears. Also dutch rabbits and rex rabbits do, to name some. Hope this is of some help :)
All rabbits have long ears...
Bunny ears serve many purposes. Bunny ears are used by the animal known as rabbits for hearing sounds. Humans use fake bunny ears for costume purposes.
Their ears have gotten longer to hear better.
