Rabbits are hairless and totally dependent on their mothers after birth.
Their big ears act as effective sound collectors and air conditioners. They help dissipate body heat. The jackrabbits that live in Yellowstone are called white-tailed jackrabbits. White-tailed jackrabbits have bright yellow eyes. Yellowstone's jackrabbits live in the sagebrush and grasslands.
