Fun facts

  • Its name comes from a historical misunderstanding: in 1696 the explorer Willem de Vlamingh mistook quokkas for giant rats.
  • It eats grasses, leaves and soft shoots, and depends heavily on fresh water nearby.
  • It lives in dense scrub, swampy ground and woodland of south-western Australia, especially on Rottnest and Bald Islands.
  • conservaciónIts expression, which looks like a permanent smile, and its lack of wariness around people have made it a social-media phenomenon, though in the wild it faces serious conservation threats.
