Pygmy Rabbit
The pygmy rabbit (''Brachylagus idahoensis'') is a rabbit species native to the United States. It is also the only native rabbit species in North America to dig its own burrow. The pygmy rabbit differs significantly from species within either the ''Lepus'' (hare) or ''Sylvilagus'' (cottontail) genera and is generally considered to be within the monotypic genus ''Brachylagus''. One isolated population, the Columbia Basin pygmy rabbit, is listed as an endangered species by the U.S. Federal government, though the International Union for Conservation of Nature lists the species as lower risk. Description The pygmy rabbit is the world's smallest leporid, with adults weighing between , and having a body length between ; females are slightly larger than males. The pygmy rabbit is distinguishable from other leporids by its small size, short ears, gray color, small hind legs, and lack of white fuzzy fur. Distribution The range of the pygmy rabbit includes most of the Great Basin and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
