, name for several small, predatory marsupials, or pouched mammals, of the family Dasyuridea, found in Australia, Tasmania, and New Guinea. Typical dasyures, known in Australia as native cats, are furry animals with large eyes, pointed snouts, and long tails.

The Tasmanian devil, Sarcophilus harrisi, formerly found also in Australia, is about 2 ft (60 cm) long, excluding the 12-in. (30-cm) tail. It has a large head, with powerful jaws, and weak hindquarters. Its blackish fur is marked with white patches on the throat, on each side, and on the rump. The animal has a fierce appearance. It is very strong for its size and preys on animals larger than itself, such as small kangaroos, as well as on rodents, lizards, and other small animals. It lives in burrows in rocky areas.

Although it survived in sizable numbers in remote areas of the island, it is now threatened by a fatal contagious facial cancer that has spread steadily and decimated infected populations since the late 1990s. In 2009 the Tasmanian devil was officially declared endangered. A lack of genetic diversity in the marsupial has facilitated the cancer's spread; the recent discovery of a possibly resistant genetically different population in W Tasmania has raised hopes for the species. Efforts are being made to establish a sizable disease-free population on the Australian mainland.
The Tasmanian devil is classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

(Sarcophilus harrisii), a mammal of the family Dasyuridae. The body length varies from 52 to 80 cm, and the tail length, from 23 to 30 cm. The head is disproportionately large. The body is covered with short black hairs. There are white patches on the snout, chest, and sides. The pouch opens posteriorly. The Tasmanian devil is distributed in Tasmania, where it inhabits forests. A nocturnal animal, it shelters during the day in rock crevices and in cavities beneath fallen trees. It feeds on a variety of vertebrates. It reproduces once a year, producing up to four young per litter. Its numbers are few.
