Rabbits are not small rodents

Domestic rabbits descend from the European rabbit, Oryctolagus cuniculus, in the family Leporidae. They are distinct from cottontails and from true hares. A breed name containing 'hare' does not move a domestic rabbit into the genus Lepus. Likewise, resemblance in body outline cannot replace scientific identity.

The incisors provide a useful anatomical distinction. Rabbits have two pairs of upper incisors, with a small pair of peg teeth behind the visible front pair, and one pair below. Their teeth continue growing. Strong hind limbs support jumping, and long ears contribute to the familiar rabbit form, although domestic breeds vary greatly in ear carriage, size and coat. Rabbits tend to be most active around dawn and dusk. The species provides a shared biological foundation, while differences among breeds remain important for describing appearance and particular care demands.
