The kangaroo embryo grows in the womb. It is born at a very early stage of development and emerges from the mother's vagina. It looks like a very tiny kangaroo. The joey then crawls up her belly fur and into the pouch. After it latches on to a nipple for feeding, it then completes its development until it is big enough to emerge.
