Western Quoll (Dasyurus geoffroii) lives in arid open woodland across Southwest Western Australia. It feeds on insects & small mammals. Its conservation status is Near Threatened.
Fascinating facts about the Western Quoll
- The western quoll is the biggest native meat-eater in Western Australia, making it the state's largest endemic mammalian carnivore. It reaches a head-and-body length of 36 to 46 cm and a tail of 22 to 30 cm, with males weighing around 1.3 kg and females 0.9 kg. Its size surpasses that of any other marsupial carnivore in the region, a distinction noted in its description as the largest endemic mammalian predator.
- Its rufous brown coat is marked with 40-70 white spots across the back, a pattern that helps diminish its outline under moonlight when hunting. The spots are distributed on a creamy-white underside, giving the animal a disruptive colouration suited to nocturnal activity. Large eyes and pointed ears further enhance its night-time vision and hearing, supporting its crepuscular hunting style.
- Male western quolls spread out over about 15 square kilometres, a range that typically overlaps with several female territories each covering 3-4 square kilometres. Female home ranges contain roughly 70 hollow-log dens and 110 burrows, providing numerous refuges and den sites. Males share their large territories with smaller female ranges, but females do not cross into other female territories, reinforcing solitary behaviour.
- The western quoll can meet the bulk of its water needs from the prey it consumes, a trait that becomes crucial when rainfall is scarce. Its diet of lizards, birds, frogs, insects and small mammals supplies enough moisture to offset the lack of free water. This physiological adaptation lets it remain active during prolonged dry periods without needing to drink, supporting its survival in arid habitats.
- A five-year trial began in April 2014 to re-establish western quolls in South Australia's Flinders Ranges, releasing an initial cohort that later lost about a third of its members, mainly to feral cats. The surviving females reproduced, producing sixty joeys, and a further release of fifteen quolls in May 2016 brought the total population to roughly 150 individuals, half of which were locally born.
