|Brown antechinus range|
The brown antechinus (Antechinus stuartii), also known as Stuart's antechinus and Macleay's marsupial mouse, is a species of small carnivorous marsupial of the family Dasyuridae. It holds the world record for being the world's smallest semelparous mammal.
The brown antechinus was only the third in its genus to be described and as such has, until recently, included species such as the agile antechinus (Antechinus agilis), the subtropical antechinus (Antechinus subtropicus) and the tropical antechinus (Antechinus adustus). It has also been included itself with the yellow-footed antechinus as the subspecies burrelli. It was described in 1841 by the entomologist William Sharp Macleay, who named the species in honour of his friend and fellow naturalist James Stuart who had discovered the animal at Spring Cove (North Head) in 1837 while working as surgeon in charge of the Quarantine Station.
The body length is 9.5 to 11 cm. The tail length is 10 to 12 cm.
The brown antechinus is mostly nocturnal and is arboreal, and females build large communal nests shared by many individuals. Like all antechinuses, the males die after their first breeding season (which lasts two weeks) as a result of stress and exhaustion. Female brown antechinuses do not possess a pouch; the young must attach themselves to the teats (of which there are usually eight). Its diet includes beetles, spiders, amphipods and cockroaches, although it is an opportunistic feeder. The litter size is 6 to 7 young.
