NEET BIOLOGY

Detailed explanation-1: -After birth, the young are transferred to a pouch where they reach maturity. Marsupials include kangaroo, wallaby and koala. In marsupials, the mammary glands, which vary in number, are located within the pouch and terminate in a teat.

Detailed explanation-2: -A marsupial is a therian mammal in which the embryo is born at an early, immature stage. The embryo completes its development outside the mother’s body in a pouch on her belly. Marsupials include the kangaroo, koala, and opossum. Only a minority of therian mammals are marsupials.

Detailed explanation-3: -They include kangaroos, koalas (above left), tasmanian devils, wombats (above right), and other typical Australian mammals. Until recently, they also included the marsupial wolf, Thylacinus (below). Like the quagga, the marsupial wolf is now extinct. The last individual was seen in Tasmania in the 1950s.

Detailed explanation-4: -It’s a common reproductive method, used by the majority of living mammal species. Marsupials, however, do things a little bit differently. Young develop inside their mother in a uterus (or two) for a short time, but they are born early and finish developing inside a special pouch.

Detailed explanation-5: -A pouch is called a marsupium. Some of the well-known marsupials are kangaroos, wallabies, wallaroos, quokkas, koalas, possums, and wombats.
