No. There are breeds who have floppy ears.
yes.
Genetics.
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 :)
They will still stand up. i have one that is 9 Weeks old and hers stand all the time. i always touch them
no they do not. hares are slightly bigger and flatten their ears while running to maintain speed while rabbits keep their ears up
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
To pick up all the sounds to see if there is any danger.
Lop ears in rabbits are a genetic trait where the ear cartilage is floppier than normal, causing the ears to hang down. This trait is passed down through generations and is commonly bred intentionally in certain rabbit breeds for their unique appearance.
I know why rabbits have long ears but i don't know the answer to why they have long hind legs the answer to you first part of the question is. Rabbits have long ears so they can detect noises or up coming danger. it also helps the rabbit cool itself down.
When they are calm, or sleeping a rabbit will lay the ears down. At this time they don't want to here. I f startled the ears go up to here. Some rabbits, (flopped eared) are born with long ears that hang down. This is because of the breed.
No their ears stand up on their own.
why does the ear of my poodle puppy stand up
