Leporidae is a family of small mammals in the order Lagomorpha. A member of this family is called a leporid, or colloquially a hare or rabbit. They are widespread worldwide, and can be found in most terrestrial biomes, though primarily in forests, savannas, shrublands, and grasslands. Leporids are all roughly the same shape and fall within a small range of sizes with short tails, ranging from the 21 cm (8 in) long Tres Marias cottontail to the 76 cm (30 in) long desert hare. Most species do not have population estimates and some are not yet evaluated for conservation status, though nine species are considered endangered and one, the riverine rabbit, is critically endangered with a population size of as low as 100. The domestic rabbit subspecies of the European rabbit has been domesticated.
