Brachylagus idahoensis (Pygmy Rabbit)

Synonyms: Lepus idahoensis; Sylvilagus idahoensis

Wikipedia Abstract

The pygmy rabbit (Brachylagus idahoensis) is a North American rabbit, and is one of only two rabbit species in 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.
