What size? Please be more deatailed
It depends on its species and size. Tiny rabbits have tiny ears.
Rabbits vary in color, size, length of ears, and length of body. Some rabbits are small and others are very large and can hop further distances.
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.
The head is shaped like half an oval. It has large straight ears or if it's a lop, floppy ears. The eye is about the same size as the nose. The Nose is triangular and it keeps moving. Rabbits have many whiskers. Lastly, the mouth has 4 main teeth that are yellowish.
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...
of course silly! :)
Their big ears!
Their ears have gotten longer to hear better.
