The latter subclass is divided into two infraclasses: pouched mammals (metatherians or marsupials), and placental mammals (eutherians, for which see List of placental mammals). Classification updated from Wilson and Reeder's "Mammal Species of the World: A Taxonomic and Geographic Reference" using the "Planet Mammifères" website. [1]

Cetartiodactyla is a large order of hoofed mammals, the even-toed ungulates, and aquatic mammals, cetaceans. Cetacea was found to be nested within "Artiodactlya" and has now been moved into that order, whose name is now Cetartiodactyla. [2] Even-toed ungulates are found nearly world-wide, although no species are native to Australia or Antarctica.
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 class Mammalia is divided into two subclasses based on reproductive techniques: monotremes, which lay eggs, and therians, mammals which give live birth, which has two infraclasses: marsupials/metatherians and placentals/eutherians. See List of monotremes and marsupials, and for the clades and families, see Mammal classification ...
Lists of mammals by region cover mammals found in different parts of the world. They are organized by continent, region, and country, and in some places by sub-national region. Most are full species lists, while those for Australia and the Caribbean have links to more specific species lists.
The South African pouched mouse or southern African pouched mouse (Saccostomus campestris) is a species of rodent in the family Nesomyidae, [2] which is viewed as actually representing a complex of at least three undescribed species. [1]
