The function of kangaroo pocket

Kangaroo's pocket is called nursing bag, which is used to feed kangaroo babies. Kangaroos have no placenta, so embryos can't mature in their mothers. Pregnancy is only 33-40 days. This premature kangaroo is less than two centimeters long and weighs less than one gram, about the size of a human finger. It can only stay in its mother's pouch and live on breast milk.

There are four nipples in the kangaroo mother's pouch. Newborn kangaroos choose nipples with suitable temperature and fat content to suck. The other three nipples are suitable for bigger kangaroos After a few weeks, when the kangaroo is big enough, it will change a nipple that is more suitable for it. Every time it grows to a stage, it will find a new suitable nipple to suck.
