The '''Quokka''' (''Setonix brachyurus'') is a small [[macropod]], about the size of a large domestic cat. Like other [[marsupial]]s in the macropod family (such as the [[kangaroo]]s and [[wallabies]]), the Quokka is herbivorous and mainly nocturnal.

In the wild, it is now restricted to a very small range in mainland south-western [[Western Australia]], where it has become rare, and on two [[fox]]-free islands off the coast: [[Bald Island]] and [[Rottnest Island]] &#8212; which is its stronghold.

Template:Taxobox The Eastern Quoll, Dasyurus viverrinus, is a medium-sized carnivorous dasyurid marsupial native to Australia. They are now considered extinct on the mainland, but remain widespread and even locally common in Tasmania. It is one of six extant species of quoll.

Description

The Eastern Quoll is generally about the size of a small domestic cat, with an adult male averaging 60cm and weighing approximatly 1.3kg. Their thick coat is covered by white spots, and ranges in colour from a light fawn to a near black, with an off-white belly. They can be distinguished from the Spot-Tail Quoll by their slender build, pointed snout and lack of spots on the tail.

Behaviourm

The Eastern Quoll is a solitary predator, hunting at night for its prey of insects and small mammals. They have also been known to scavenge food from the much larger Tasmanian Devil.

The breeding season begins in early winter, and the female gives birth to up to 30 young. Of these, the first to attach themselves to the six teats will be the only survivors. Weaning takes place at about 10 weeks of age, with the young staying in the den whilst the mother forages.

Threats

The main threats to the Eastern Quoll are competition and predation from feral cats and illegal poisoning and trapping. The lack of foxes and dingoes in Tasmania is believed to have contributed to the survival of the species.
