from Wikipedia:

The Tasmanian devil (Sarcophilus harrisii) is a carnivorous marsupial, now found in the wild only on the Australian island state of Tasmania. The size of a small dog, it became the largest carnivorous marsupial in the world following the extinction of the thylacine in 1936. It is characterised by its stocky and muscular build, black fur, pungent odour, extremely loud and disturbing screech, keen sense of smell, and ferocity when feeding. The Tasmanian devil’s large head and neck allow it to generate the strongest bite per unit body mass of any living mammal, and it hunts prey and scavenges carrion as well as eating household products if humans are living nearby. Despite its rotund appearance, the devil is capable of surprising speed and endurance, and can climb trees and swim across rivers.

A devil tooth found in Augusta, Western Australia has been dated to 430 years ago, but archaeologist Oliver Brown disputes this and considers the devil’s mainland extinction to have occurred around 3000 years ago.[2] This disappearance is usually blamed on dingoes, which are absent from Tasmania. Because they were seen as a threat to livestock and animals that humans hunted for fur in Tasmania, devils were hunted and became endangered. In 1941, the devils, which were originally seen as implacably vicious, became officially protected. Since then, scientists have contended that earlier concerns that the devils were the most significant threat to livestock were overestimated and misplaced.

Devils are not monogamous, and their reproductive process is very robust and competitive. Males fight one another for the females, and then guard their partners to prevent female infidelity. Females average four breeding seasons in their life and give birth to 20–30 live young after three weeks’ gestation. As there are only four nipples in the pouch, competition is fierce and few newborns survive. The young grow rapidly and are ejected from the pouch after around 100 days, weighing roughly 200 g (7.1 oz).

Since the late 1990s, devil facial tumour disease has drastically reduced the devil population and now threatens the survival of the species, which in 2008 was declared to be endangered. Programs are currently being undertaken by the Government of Tasmania to reduce the impact of the disease, including an initiative to build up a group of healthy devils in captivity, isolated from the disease. While the thylacine was extant it preyed on the devil, which targeted young and unattended thylacine cubs in their dens. Nowadays, the devil is also preyed upon by the illegally introduced red fox, and localised populations of devils have also been severely reduced by collisions with motor vehicles, particularly when they are eating roadkill themselves.
