Kangaroo joey inside the pouch Female eastern grey kangaroo with mature joey in pouch. The pouch is a distinguishing feature of female marsupials and monotremes, [1] [2] [3] and rarely in males as well, such as in the yapok [4] and the extinct thylacine. The name marsupial is derived from the Latin marsupium, meaning "pouch".
The 19 known species of rock-wallabies (genus Petrogale) live among rocks, usually near water; two species in this genus are endangered. The two living species of hare-wallabies (genus Lagorchestes; two other species in this genus are extinct) are small animals that have the movements and some of the habits of hares.
For them, the reproductive tract is doubled. The females have two uteri and two vaginas, and before birth, a birth canal forms between them, the median vagina. [7] In most species, males have a split or double penis lying in front of the scrotum, [8] which is not homologous to the scrotum of placentals. [9] A pouch is present in most, but not ...
Whiptail wallaby mobs have a linear hierarchy that is determined by ritualized “pawing”, which is non-violent. [7] They may also pull grass. Whiptail wallabies will cough to show submission. These bouts function only to determine access to oestrous females. [7] A female whiptail wallaby with a joey.

Lagorchestes is a genus of small, rabbit-like mammals commonly known as hare-wallabies. It includes four species native to Australia and New Guinea, two of which are extinct. Hare-wallabies belong to the macropod family (Macropodidae) which includes kangaroos, wallabies, and other marsupials.
About the size of a stout cat, it lives mainly under thick plant cover, and is only active at night when it emerges to feed on grasses and small plants. It is the smallest of the wallabies (short, kangaroo-like marsupial mammals of the genus Notamacropus) and carries its young in a pouch, as with other marsupials. Shy and elusive, it was ...
The tammar wallaby (Notamacropus eugenii), also known as the dama wallaby or darma wallaby, is a small macropod native to South and Western Australia.Though its geographical range has been severely reduced since European colonisation, the tammar wallaby remains common within its reduced range and is listed as "Least Concern" by the International Union for Conservation of Nature (IUCN).
