Rabbits
are small mammals in the family Leporidae, found in many
parts of the world. There are seven different genera in
the family classified as rabbits, including the European
Rabbit (Oryctolagus cuniculus), cottontail rabbits (genus
Sylvilagus; 13 species), and the Amami Rabbit (Pentalagus
furnessi, an endangered species on Amami Oshima, Japan).
They are distinguished from the related hares in that
they are altricial, having young that are born blind and
hairless; many also live underground in burrows. For jackrabbits,
which are actually hares, in the genus Lepus, see hare.
Rabbits vary in size and weight. As a lagomorph, they
have 4 sharp incisors (2 on top, 2 on bottom) that grow
continuously throughout their life, and two peg teeth
on the top behind the inscisors, dissimilar to those of
rodents (which have only 2 each, top and bottom). |
