When moving at top speed, rabbits can run at 18 to 20 mph. Jackrabbits, which are technically hares, can run at 35 to 45 mph. The gray fox, a common predator of rabbits, can run at up to 42 mph.
Rabbits and hares are closely related. Hares are larger and faster than rabbits and usually live alone. Baby hares are born with fur and are able to move immediately after birth. Jackrabbits tend to live on open grasslands and use their speed to escape from predators. Rabbits tend to live on the borders between woodlands and meadows. They live in social groups. Their babies are born blind and helpless. Rabbits generally try to escape predators by hiding. When they flee from predators, they run in a zigzag pattern.
