What is Leporidae?

    Leporidae is a family of animals comprising the rabbits and bares. With the Lagomyidae it constitutes the suborder Duplicidentata, distinguished from the rodents by having two pairs of upper incisors, of which the second is much reduced in size and placed immediately behind the first and larger pair. The hind-legs are much longer than the fore-legs and are well adapted by their structure for the leaping mode of locomotion affected by these animals; the tibia and fĂ­bula are completely ankylosed and articulate with the calcaneum by a pulley-like surface, thus combining great strength with great freedom of movement in one plane. The family is now cosmopolitan, some 75 species and sub-species being recognized in North America. The genus Lepus is practically coextensive with the family.
