Tasmanian Tiger, Tasmanian Wolf, or Thylacine, the largest meat-eating marsupial. (A marsupial is an animal whose young are suckled and carried in a pouch on the female's abdomen.) It was once a serious threat to livestock and was hunted to such an extent that it may be extinct; a few, however, may survive in the forested areas of Tasmania. The last captive Tasmanian tiger died in a zoo in 1936.
The name “tiger” refers to the blackish brown stripes across the back and at the base of the tail. The name “wolf” refers to the animal's wolflike head. The animal is not related to the tiger or the wolf.
The Tasmanian tiger is about 23 inches (58 cm) tall at the shoulder. It is about 50 inches (127 cm) long, including a 19- to 24-inch (48- to 61-cm) tail, and weighs about 65 pounds (29 kg). The Tasmanian tiger is gray or yellowish-brown in color. It sleeps during the day in a cave or hollow log. It is active at night and hunts in small groups for kangaroos, wallabies, and sheep.
The Tasmanian tiger is Thylacinus cynocephalus of the family Thylacinidae.
