So they can hear better, and hear if a predator is approaching them.
Like many animals, rabbits will turn their ears toward noise so they can better hear if a predator is approaching.
Rabbits turn their ears to collect sound.
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.
For the same reason you turn around when talking on a cell phone and the signal get broken. By changing the direction of the receiver you get a better signal.
The plural form for rabbit ears is (one) rabbit's ears; or (two) rabbits' ears.
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.
Rabbits are lagomorphs which means they have large back feet, gnawing teeth, and large ears. Since they have large ears, they can hear all the sounds around them. Whenever a rabbit hears a sound, his or her ears turn in that direction. It's their instinct. When all rabbits were wild, they depended on their sound catching ears! So coyotes or another predator could be detected before the coyote has some fast food!
Because us humans have bred them that way. Someone got a rabbit with floppy ears, thought it was cute, and decided to breed from it. In the wild, floppy ears is no good. Reduces hearing sensitivity and increases the risk for ear infections, for both rabbits as well as floppy eared dogs. But as pets, it doesn't matter. They survive well enough anyhow.
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 :)
Rabbits' ears are on top of their heads because they can quickly turn in any direction. Rabbits are prey animals, and this helps them hear predators better. Monkeys are not generally preyed upon, and they use their brains more to avoid danger than their ears. Since they do not rely as much on hearing, their ears are located at the sides of their heads.
All rabbits have long ears...
