Own Genus: Quokkas are a genus of their own. It is believed that they and the swamp wallaby are both relics of separate lines of evolution from early browsing macropods.
Survivors: Quokkas are very well adapted. They are able to survive in an environment virtually devoid of freshwater by digging waterholes and feeding on succulent plants. They are also able to climb low trees.
They have excellent thermoregulation coping with temperatures up to 44 degrees Celsius.
Rottnest Island: The Dutch navigator Williem de Vlamingh arrived on Rottnest in 1696 and described the Quokka as "a kind of rat as big as a common cat". He then named the Island 'Rotte nest' (meaning 'rat's nest') and the name of the Island was eventually adapted to 'Rottnest'.
