Zoology

noun

Treated as plural. An order of mammals comprising forms which lack a complete placenta and give birth to very immature young which complete their development while attached to the mother's mammae, typically located in a protective abdominal pouch.

By some recent authors, each of the main marsupial groups is treated as equivalent to an order, Marsupialia being termed a cohort..

Origin

Mid 19th century; earliest use found in Henry McMurtrie (1793–1865). From scientific Latin Marsupialia from post-classical Latin marsupialis + -a.
