1. Metatheria

   Metatheria is a mammalian clade that includes all mammals more closely related to marsupials than to placentals. First proposed by Thomas Henry Huxley in 1880, it is a more inclusive group than the marsupials; it contains all marsupials as well as many extinct non-marsupial relatives.

1. metatheria

   Metatheria is a mammalian group or clade that includes marsupials and their extinct relatives. These mammals are characterized by giving birth to relatively undeveloped young which continue to develop outside the womb, usually within a pouch. This separates them from placental mammals, which give birth to more fully developed young. They first appeared in the fossil records during the late Cretaceous period around 100 million years ago.

1. Metatheria

   Metatheria is a grouping within the animal class Mammalia. First proposed by Thomas Henry Huxley in 1880, it is a slightly more inclusive group than the marsupials; it contains all of the living mammals with abdominal pouches as well as all animals more closely related to them than to placental mammals like armadillos and humans. Some female metatherians, like the shrew opossum, lack a pouch. The closest relatives of the metatheres are the Eutheria. Both are conventionally united as infraclasses within the subclass Theria, which contains all living mammals except monotremes. During development, metatherians produce a yolk-sac placenta and give birth to "larval-like" offspring. These offspring have underdeveloped posterior limbs, and following birth they migrate to the pouch where they attach to a nipple. The mouth of newly-born metatherians is fused laterally, but open medially; this forms an "O" shaped mouth in which the mother's nipple fits; it then swells to secure the offspring into place for further development and growth. The combination of the Greek elements meta- and theria in this usage roughly means the "sort-of-beasts" or " behind-beasts", in contrast with Eutheria.
