[MUSIC] JOAN CARTAN-HANSEN, HOST: Rabbits and hares look a lot alike, but they are actually very different. Hares typically have longer ears than rabbits. And they have black tips on the ends of their ears. Rabbit ears are shorter and some domesticated breeds like the Holland Lop-Eared bunny have ears that droop. Wild hares and rabbits avoid predators in different ways. Rabbits live in underground holes called burrows. When a predator threatens, rabbits run underground. Hares live in nests above ground. They try to outrun predators, so hares developed longer legs and bigger feet than rabbits. Rabbit babies are called kits and they're helpless when they are born. They have to live in their underground home for more than two weeks before they're ready for the outside. Hare babies are called leverets and they're born ready to run. Wild rabbits live in groups. Hares tend to live as a pair or on their own. And one rabbit isn't a rabbit at all. The jackrabbit is actually a hare. For more information about rabbits, check out the Science Trek website.
