The Brown Antechinus (Antechinus stuartii), also known as Stuart's Antechinus, Brown Marsupial Mouse, Stuart's Marsupial Mouse, and Macleay's Marsupial Mouse, is a species of small carnivorous marsupial of the family Dasyuridae. The males die after their first breeding season, and the species holds the world record for being the world's smallest semelparous mammal.
They are also sometimes called 'broad-footed marsupial mice', 'pouched mice', or 'Antechinus shrews'. However, the majority of those common names are considered either regional or archaic; the modern common name for the animal is antechinus.
Antechinus is primarily light brown on top, including the tops of its foot, and lighter brown on the underside and tail. It weighs 16–44 g (0.56–1.55 oz) and has a body length of 93–130 mm (3.7–5.1 in) and a tail length of 92–120 mm (3.6–4.7 in). Brown Antechinus does not have a pale-colored eye ring like other Antechinus species do. With the exception of distribution, Agile Antechinus is difficult to differentiate due to its identical appearance.
Antechinuses will remain in their home range and experience torpor after a fire, which lowers their need for foraging and lowers their danger of being eaten by predators.
Antechinus undergoes intensive mating, which in some species can last up to 12 hours. The litters have various fathers since the males mate with numerous females.
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. The current accepted hypothesis to why this happens is that sperm competition drives increased male investment in reproduction. 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 six or seven young.
Increased physiological stress results from aggression and competition between males for females, and heightened activity during breeding season.
This adorable marsupial breeds itself to extinction. It's simply one of the factors contributing to the extinction of two of the 15 antechinus species. However, the main culprits are habitat loss, climate change, invasive species, and excessive sex during a three-week period that causes males to get blind and perish.
In Australia, the brown antechinus can be found east of the Great Dividing Range from southeast Queensland to close to Kioloa, New South Wales. The majority of its habitats are wooded, with dense lower ground cover and few fires.
