Species Profile: Quokka

Hello again, welcome back to animals under threat. Today, we will be covering an animal that has been described as the “happiest animal in the world”. Say hello to the adorable Quokka (Setonix brachyurus).

The Quokka is a tiny marsupial that is the only member of the genus (Setonix) and was mistaking thought to be a rat by early Dutch explorers. They are mostly found in far Southwestern mainland Australia and on several islands off the Southwest coast, mainly on Rottnest island. Quokkas are characterized by their thick brown-grey fur, wide puffed-out cheeks, short pointed muzzle, rounded ears and short tail (Campbell & Woods, 2013).

Quokkas live in swamp areas that contain the tea-tree (Taxandria linearifolia) also nickname “swamp peppermint”. They also live in woodland areas that contain Eucalyptus marginate, Corymbia calophylla, E. diversicolor and E. jacksonii which the Quokka can climb and feed on (Burbidge & Woinarski, 2019). The shrub Guichenotia ledifolia is considered to be the Quokkas favourite plant to feed on and receive water from the food they eat (Hayward, 2005).

Quokkas have little fear of humans and have been known to approach people camping, cafes, and other areas where humans eat. When Quokkas eat human food, they become very sick and dehydrated leading the Quokka to be at risk from predators and car accidents. Predation by Red foxes and feral cats on islands has led to a decline in the population and habitat degradation of the swamps by feral pigs has cause the food shortage (Burbidge & Woinarski, 2019).
 
Next time, we will be covering a species of crane that is believed to mate for life and preform courtship dances.
