A pika (/ˈpaɪkə, ˈpiːkə/ PY-kə, PEE-kə[3][4]) is a small, mountain-dwelling mammal native to Asia and North America. With short limbs, a very round body, an even coat of fur, and no external tail, they resemble their close relative the rabbit, but with short, rounded ears.[5] The large-eared pika of the Himalayas and nearby mountains lives at elevations of more than 6,000 m (20,000 ft).
The name pika appears to be derived from the Tungusic piika,[6][7] and the scientific name Ochotona is derived from the Mongolian word ogotno (оготно), which means 'pika'.[8] It is used for any member of the Ochotonidae,[9] a family within the order of lagomorphs, the order which also includes the Leporidae (rabbits and hares). They are the smallest animal in the lagomorph group.[10] Only one genus, Ochotona[9] (/ˌɒkəˈtoʊnə/ OK-ə-TOHN-ə),[11] is extant within the family, covering 37 species, though many fossil genera are known. Another species, the Sardinian pika, belonging to the separate genus Prolagus, has become extinct within the last 2,000 years owing to human activity.
