Tasmania has many unique mammals found nowhere else in the world. Some, like the Tasmanian devil and the now extinct Tasmanian tiger are well-known. Others, such as the eastern quoll, pademelon and bettong are less well-known.
Tasmania has many species which have become, or are on the verge of extinction on mainland Australia. The lack of introduced predators, such as the fox, and the relatively large amount of intact habitat on the island, make Tasmania a final refuge - a last chance - for many species.
