Sugar glider

The sugar glider (*Petaurus breviceps*) is a small, nocturnal, arboreal marsupial known for gliding between trees using a skin membrane.

Updated September 11, 20261 min readCited sources

The sugar glider is a small, nocturnal marsupial that glides between trees using a skin membrane. Native to Australia and New Guinea, it's a social forest dweller listed as least concern.

What it is

The sugar glider (*Petaurus breviceps*) is a marsupial possum in the family Petauridae. It has a gliding membrane called a patagium between its wrists and ankles, large eyes, and a long tail. Recent taxonomic revisions have split some populations into separate species.

Key details

Sugar gliders are nocturnal and live in forests and woodlands, often in eucalyptus habitats with tree hollows for shelter. They are omnivorous, feeding on sap, nectar, pollen, insects, and fruit. Social animals, they typically live in small family groups or colonies.

Why it matters

The species is classified as least concern by the IUCN, meaning it's not globally threatened. However, its social and dietary needs make it a complex animal in captivity. In Canada, sugar gliders are not native but appear in zoos and exotic pet discussions.

In short

  • Small gliding marsupial native to Australia and New Guinea.
  • Nocturnal, social, and lives in forest habitats with tree hollows.
  • Diet includes sap, nectar, insects, and fruit.
  • Listed as least concern; not endangered.
Canadian angle

Sugar gliders are not native to Canada, but they are sometimes kept in captivity elsewhere as exotic pets and are familiar to Canadian readers through zoos, wildlife education, and pet care discussions.
