Why does the Kangaroo carry its young one in its pouch?
The baby kangaroo called joey is born in an underdeveloped state. So they complete developing inside the pouch which gives the little kangaroo its milk, shelter and even oil to keep it moist. The joey spends its first five months in the pouch completely. At the end of this time, the joey pokes its head out, but does not venture out. Finally at eight months, the joey leaves the pouch for good.
