Kangaroo's 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.
