The quokka (Setonix brachyurus) is a small marsupial found in southwestern Australia.and Rottnest and Bald Islands. Rottnest Island was named by a Dutch explorer who thought the quokkas living there were rats.
Quokkas resemble small wallabies. They have short brown furs, short ears, and sparsely haired tail. They weigh 5.5-10 pounds.
Quokkas inhabit dry arid scrub forests where they consume a variety of grasses.
Female quokkas are polyestrous and their cycle may last 4 weeks. After gestation period of roughly the same time, a single young is born. A day after its birth, the mother may mate again. The young reach maturity at 9-12 months of age.
The quokka is listed as “vulnerable” by the IUCN. Their populations are decreasing as a result of introduced predators such as foxes and cats. Habitat clearing has also had a major effect in their declines.
