Rabbits are small, furry, mammals with long ears, short fluffy tails, and strong, large hind legs. They have 2 pairs of sharp incisors (front teeth), one pair on top and one pair on the bottom. They also have 2 peg teeth behind the top incisors. Their teeth are specifically adapted for gnawing and grow continuously throughout their lives.
Using their powerful hind legs, rabbits move by hopping. They have 4 toes on their hind feet that are long and webbed to keep them from spreading apart as they jump. Their front paws have 5 toes each. Some species of rabbit can reach speeds of 35 to 45 miles per hour (55 to 70 kilometers per hour). Young rabbits seem to walk instead of hop.
