The pika differs from the rabbit in that its body is smaller and the ears on its blunt head are shorter; also unlike the rabbit, the fore and hind limbs are about equal in length. The pika moves with a scampering gait. Its fur varies from red to gray and covers the soles of its feet. Pikas generally shelter in communities beneath rocks, although some Asian species burrow. Their diet consists primarily of green plants. Because food is difficult to obtain in winter in the harsh tundra environment, pikas cut, sun-dry, and store vegetation for winter use. Pikas are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.
