you need a rabbit
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.
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...
Genetics.

Their big ears!
Some rabbit ears are referred to as "Lop," which describes a breed of rabbits known for their droopy ears. These ears give them a distinctive appearance compared to other breeds that have upright ears.
