Do rodents have long ears and large hind legs?

Not all rodents have long ears and large hind legs. These features are more characteristic of specific types of rodents, like:

* Rabbits and Hares: These are not technically rodents, but lagomorphs. They have long ears and large hind legs adapted for hopping.

* Jerboas: These are small desert rodents with extremely long hind legs and very short forelegs, built for jumping and running.

* Kangaroo Rats: These rodents have long hind legs and a long, thick tail, which help them jump and balance.

Many other rodents do not have these features:

* Rats and Mice: These rodents have short ears and relatively normal-sized legs.

* Squirrels: While some squirrels have large hind legs, others do not.

* Beavers: Beavers have short, strong legs.

So, while some rodents do have long ears and large hind legs, it's not a defining characteristic of all rodents.
