The Tasmanian Devil is a carnivorous marsupial found exclusively on the Australian island of Tasmania. At the size of a small dog, but stocky and muscular, the Tasmanian Devil is the largest carnivorous marsupial in the world. The devil is characterised by its black fur, offensive odour when stressed, extremely loud and disturbing screech, and vicious temperament when feeding. Known to hunt, as well as to scavenge carrion, communal eating is one of the few social activities in which the usually solitary devil participates. The Tasmanian Devil became extinct on the Australian mainland about 400 years prior to European settlement in 1788. The people of Tasmania saw devils as a threat to livestock and hunted them until 1941, when the animals were officially protected. Since the late 1990s devil facial tumour disease has reduced the devil population significantly and threatens the survival of the species. The impact of the disease on devil population may lead to listing of the devil as an endangered species.
