Female Anatomy

The pouch of a female Eastern Grey kangaroo; the most obvious distinguishing characteristic between marsupials and placentals. The joey, when newly born and in a very early stage of development, crawls up the female's fur from the birth canal in the cloaca (see below) to the pouch, clamps onto a nipple and continues its development in there.

The cloaca of the same kangaroo, in its normal state. Marsupials, instead of having separate openings for anus and vagina, have only a shallow cloaca which serves both functions.

The cloaca when relaxed and open.
