A kangaroo, also a marsupial like koala, is from the family of Macropodidae (Macropods, meaning 'large foot'). Like all marsupials, the baby of kangaroo is born at a very early stage of development after a gestation period of 31 to 36 days which only the forelimbs are developed to allow it to climb to its mother's pouch and attach to a teat. In comparison, a human embryo at a similar stage of development would be only seven weeks old. When the joey is born, it is the size of a lima bean. The joey will usually stay in the pouch for about nine months before being confident enough to leave the pouch for small periods of time. It is usually fed by its mother until reaching 18 months old.
