Rabbits are small mammals in the family Leporidae of the order Lagomorpha (along with the hare and the pika). Oryctolagus cuniculus includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. Sylvilagus includes thirteen wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit (or bunny) is, in many areas of the world, a part of daily life—as food, clothing, and companion, and as a source of artistic inspiration.
Hares and jackrabbits are leporids belonging to the genus Lepus. Hares are classified into the same family as rabbits. They are similar in size and form to rabbits and eat the same diet. They are generally herbivorous and long-eared, they are fast runners, and they typically live solitarily or in pairs. Hare species are native to Africa, Eurasia, North America, and the Japanese archipelago.
Five leporid species with "hare" in their common names are not considered true hares: the hispid hare (Caprolagus hispidus), and four species known as red rock hares (comprising Pronolagus). Meanwhile, jackrabbits are hares rather than rabbits.
A hare less than one year old is called a leveret. The collective noun for a group of hares is a "drove".
