Black-tailed jackrabbits are not actually rabbits, but are hares. Hares are born with fur and are larger than rabbits. They usually have taller hind legs and longer ears.
These speedy animals are capable of reaching 40 miles (64 kilometers) an hour. They have powerful hind legs that can propel them on leaps of more than 10 feet (3 meters). They use these leaps and a zigzag running style to evade their many predators, including coyotes.
Jackrabbits produce a lot of young called leverets or bunnies. Females give birth to several litters a year, each with one to six young. The young mature quickly and require little care from their mothers.
