Possums are small to medium-sized arboreal marsupials native to Australia, New Guinea, and parts of Indonesia, with some species introduced elsewhere such as New Zealand. The term is sometimes used in North America for the Virginia opossum, but true possums are a different group of marsupials. Possums are not native to Canada, but Canadian readers may encounter the term in North American English, where it is sometimes used informally for the Virginia opossum.

Classification and range

True possums are Australian and Australasian marsupials in the suborder Phalangeriformes. They are distinct from opossums, which belong to a different marsupial order in the Americas.

Appearance and behaviour

Possums are generally small to medium-sized, nocturnal, and adapted to life in trees. They often have long tails, woolly fur, and hind feet adapted for climbing.

Diet and ecology

Possums are omnivores, although many species eat mostly plant matter. Their diet can include leaves, fruit, flowers, insects, and other small food items depending on the species.

Name confusion with opossums

The word "possum" is commonly used in North America for the Virginia opossum, but that animal is technically an opossum. True possums and opossums are separate groups that only resemble each other superficially.

Key facts

  • Possums are marsupials in the suborder Phalangeriformes.
  • They are native to Australia, New Guinea, and Sulawesi, and some have been introduced to New Zealand.
  • They are typically nocturnal and live mainly in trees.
  • Possums have long tails and many species have soft fur and prehensile tails.

What is a possum?
A possum is a small to medium-sized arboreal marsupial native to Australia and nearby regions. True possums belong to the suborder Phalangeriformes.
Are possums dangerous?
Possums are generally not dangerous to people. Like most wild animals, they may bite or scratch if handled or cornered, but they are usually shy and avoid conflict.
What do possums eat?
Possums are omnivores. Many species eat mostly plant material such as leaves, fruit, and flowers, but some also eat insects and other small animals.
How long do possums live?
Lifespan varies by species and environment, but many possums live only a few years in the wild and longer in captivity.
Do possums carry rabies?
Rabies is not known to be a common disease in possums, and their lower body temperature makes them less suitable hosts for the virus than many other mammals.
What is the difference between a possum and an opossum?
True possums are Australasian marsupials in the suborder Phalangeriformes, while opossums are American marsupials in the order Didelphimorphia. In North America, "possum" is often used informally for opossums.
