Tasmanian Devil

The Tasmanian Devil, also referred to simply as 'the devil', is a carnivorous marsupial now found in the wild only in the Australian island state of Tasmania. The size of a small dog, but stocky and muscular, the Tasmanian Devil is now the largest carnivorous marsupial in the world after the extinction of the Thylacine in 1936. It is characterised by its black fur, offensive odor when stressed, extremely loud and disturbing screech, and viciousness when feeding. It is known to both hunt prey and scavenge carrion and although it is usually solitary, it sometimes eats with other devils.

The Tassie Devil is the largest surviving carnivorous marsupial in Australia. It has a squat and thick build, with a large head and a tail which is about half its body length. The devil stores body fat in its tail, so unhealthy devils often have thin tails. Unusual for a marsupial, its forelegs are slightly longer than its hind legs. Devils can run up to 13 km (8.1 mi) per hour for short distances. The fur is usually black, although irregular white patches on the chest and rump are common. Males are usually larger than females, having an average head and body length of 652 mm (25.7 in), with a 258 mm (10.2 in) tail, and an average weight of 8 kg (18 lb). Females have an average head and body length of 570 mm (22 in), with a 244 mm (9.6 in) tail, and an average weight of 6 kg (13 lb). The average life expectancy of a Tassie Devil in the wild is estimated at six years, although they may live longer in captivity.

The devil has long whiskers on its face and in clumps on the top of the head. These help the devil locate prey when foraging in the dark, and aid in detecting when other devils are close during feeding. When agitated, the devil can produce a strong odour, its pungency rivaling even the skunk. Hearing is its dominant sense, and it also has an excellent sense of smell. Since devils hunt at night, their vision seems to be strongest in black and white. In these conditions they can detect moving objects readily, but have difficulty seeing stationary objects. An analysis of mammalian bite force relative to the body size shows that the devil has the strongest bite of any living mammal. The power of the jaw is in part due to its comparatively large head. The devil also has one set of teeth that grows slowly throughout its life.
