Updated September 11, 20261 min readCited sources

The quokka is a small marsupial native to southwestern Australia. It is best known for its apparent smile, but it is a wild herbivore and mainly nocturnal.

What it is

The quokka is a small wallaby-like marsupial belonging to the macropod family, which also includes kangaroos and wallabies. It has grey-brown fur and short ears, making it one of the smallest members of the group.

Why it matters

Quokkas are listed as Vulnerable on the IUCN Red List, facing threats from habitat loss and introduced predators. Island populations on Rottnest and Bald Island are especially important for the species' survival.

Key details

Quokkas are herbivores that eat grasses, leaves, stems, bark, shrubs, and succulents. They are mainly nocturnal and feed in vegetated areas. Their “happy” expression comes from the shape of their face rather than their mood.

In short

  • Small marsupial in the macropod family
  • Native to southwestern Australia, mainly on Rottnest and Bald Islands
  • Herbivore that eats grasses and plants
  • Listed as Vulnerable, not endangered
