Not only is the Patagonian opossum the only member of its genus, it is also the most southerly occurring marsupial in the world (3) (4). As an adaptation to life in a cold climate, its fur is short and fine, yet extremely dense, insulating the Patagonian opossum against the harsh prevailing conditions (4) (5). The relatively short tail, which may become swollen with fat, is also covered in a dense fur of short fine hairs (3) (6). This peculiar species is more adapted to a terrestrial and carnivorous lifestyle than other opossums in South America, with long canines, a short, broad muzzle, strong, robust legs and elongated claws (3) (4). The upperparts are dark greyish-brown, with black eye rings and white cheek patches, and the underparts and legs are whitish (3) (5). Like other opossums, this species has well developed eyesight as well as long, touch sensitive whiskers and acute hearing. When threatened, it will warn the intruder of its aggressive nature by curling back its lips and opening the mouth to reveal rows of sharp teeth (6).
