• Class: Mammalia; Order: Lagomorpha
• There are 2 families of lagomorphs: the Leporidae (rabbits and hares) and the Ochotonidae (pikas). Pikas have small, round ears, no external tail, and live at high altitudes.
• Separate from the rodents
• Lagomorphs are hindgut digesters, which means most of their digestion takes place in the large intestine and cecum. The cecum is x10 bigger than the stomach. It produces cecotropes or "night feces" that are rich in minerals, vitamins, and proteins. Lagomorphs eat these to meet their nutritional requirements
• Rabbits compared to hares:
o Newborn rabbits are altricial (young that are born blind and hairless). Newborn hares (including the jackrabbit) are precocial (born with eyes open and fully furred).
o All rabbits except the cottontail live underground in burrows or warrens. Hares live in simple nests above the ground and usually do not live in groups.
o Hares are generally larger than rabbits, with longer ears
o Hares have not been domesticated, while rabbits are often kept as house pets.
