lagomorph
any member of the mammalian order made up of the relatively well-known rabbits and hares (family Leporidae) and also the less frequently encountered pikas (family Ochotonidae). Rabbits and hares characteristically have long ears, a short tail, and strong hind limbs that provide a bounding locomotion. In contrast, the smaller pikas have shorter, rounded ears, no external tail, and less-well-developed hind limbs associated with scampering locomotion.
