Answer:
The Tasmanian Devil (Sarcophilus harrisii) is a carnivorous marsupial mammal that is native to Tasmania. It was once widespread on the Australian mainland, but the arrival of the Dingo and possibly climate change at the end of the last ice age, may have contributed to its extinction on the mainland.
Their habitat is eucalypt forest, woodlands, heath and farmland. They are terrestrial and mostly nocturnal and eat insects, mammals up to the size of a wombat, and carrion. They can live to 6 years, or up to 8 in captivity.
Females are mature at 2 years and breed in March producing 2 young in the first year and 3 to 4 per year for the next 3 years. The gestation period is about a month. After birth, they remain in their mother's backward facing pouch for 15 weeks and are then left in the den. By October, they are weaned and follow the mother out looking for food.
They have a compact muscular body with a broad head and small eyes, black fur with a white streak across the chest and maybe one across the rump.
Males grow to about 650 mm and 9 kg, females grow to 570 mm and 7 kg.
The Tasmanian devil earned its common name because of its blood-curdling nocturnal screams.
From about 1996, the Tasmanian Devil has been threatened by a fatal form of cancer called "Devil Facial Tumour Disease (DFTD)" which has killed more than 90% of adults in high density areas and 45% of adults in medium to low density areas resulting in an "Endangered" classification.
