Why might a desert rabbit have such big ears?
- so that it looks like a rabbit
- to create a waxy surface over a hollow area for storing water

Rabbit ears are filled with blood vessels that run close to the surface. These blood vessels respond to the environment and internal conditions to help the rabbit regulate its body temperature. The ears also help rabbits listen for dangerous situations.
