Kangaroo

A kangaroo is a marsupial mammal in the family Macropodidae. Typically, It has greatly enlarged hind eggs, a strong, muscular tail, small head, and large ears. It usually moves in a hopping gait. The fore part of the kangaroo's stomach has been modified for the bacterial fermentation of plant cellulose, which makes that material digestible. Female kangaroos have an abdominal pouch for carrying their young, which are born in a rather underdeveloped state. Although the period of gestation, or pregnancy, may be short, generally ranging from 27 to nearly 40 days, the young may spend a long period in the pouch; in the case of the red kangaroo, Macropus rufus, they remain nearly 8 months.
