'''Kangaroos''' are the largest [[Marsupials]] alive today. They are now native to the continent of [[Australia]]. There are four sub-kinds in the kangaroo [[baramin]] -- the Western Grey Kangaroo, the Eastern Grey Kangaroo, the Red Kangaroo, and the Antilopine Kangaroo -- or at least sixty-nine [[species]] according to evolutionary views,{{fact}} which include wallabies and tree-kangaroos.

==Description==

Species which have this unusual ability normally mate again soon after the female gives birth. The tiny newly born kangaroo (less than 25 mm long) moves unaided into its mother's pouch and attaches itself to one of four teats. During the early stages of pouch life the young is permanently attached to the teat, but as it matures and begins to grow hair it also develops the ability to release and reattach itself to the teat.

During the early stages of pouch life the young is permanently attached to the teat, but as it matures and begins to grow hair it also develops the ability to release and reattach itself to the teat.

In the late stages of pouch life, once it has a thin covering of fur, the young one begins to explore the outside world for increasing lengths of time until eventually it is old enough to be excluded permanently from the pouch. Complete weaning may take a number of months more after the young has permanently left the pouch. If the mother gives birth during this time, the newborn young will attach itself to a different teat to that being used by the older young. It is remarkable that when this happens the mother produces two different kinds of milk for the two different-aged young.<ref>[http://www.environment.gov.au/biodiversity/trade-use/wild-harvest/kangaroo/biology.html#kanfam "Kangaroo Biology"], Austalian Government</ref>
