Tasmanian wolf, also called Tasmanian tiger because of its striped back, is an extinct wolf like carnivorous marsupial. Despite its name, this animal is neither a tiger nor a wolf. As a marsupial, it was not closely related to these placental mammals, but because of convergent evolution it displayed the same general form and adaptations. Its closest living relative is thought to be either the Tasmanian devil or numbat. The extinction of the Tasmanian wolf is attributable solely to activities of human beings, it was said to become extinct in 1936.
