Is a Possum and an Opossum the Same Thing?

Possums and opossums may sound alike, but they are separate species with unique characteristics. Here’s what sets them apart:

  1. Geographic Distribution: Possums are native to Australia, New Zealand, and nearby regions, while opossums are found in North and South America.
  2. Taxonomic Classification: Opossums belong to the order Didelphimorphia and are the only marsupials found in the Americas. On the other hand, possums belong to the order Diprotodontia and are marsupials found in Australia and surrounding areas.
  3. Behavior and Appearance: Opossums are known for their prehensile tail and unique defense mechanism of “playing dead.” Similar to kangaroos, possums have a different body structure and cannot play dead

Opossums vs. Possums Quick Facts

CharacteristicOpossum (North America)Possum (Australia/New Zealand)
LocationNorth America, mainly United StatesAustralia, New Zealand, and some in Indonesia
FamilyDidelphidaePhalangeridae
SizeLarger, up to 40 inches in length including tailVaries greatly depending on species, but generally smaller than opossums
AppearanceGenerally grayish-white fur with long, hairless, prehensile tail.Fur color varies greatly, from golden to black. Tails are often furry, and some have prehensile tails.
BehaviorKnown to “play dead” when threatened. Nocturnal and solitary.Many are arboreal (tree-dwelling) and nocturnal.
DietOmnivorous, eating anything from insects, small rodents, fruits, to garbage.Mostly herbivorous, eating leaves, fruits, and flowers, though some species also eat insects and small animals.

The Benefits of Possums and Opossums in Gardens


Despite their differences, possums and opossums play valuable roles in garden ecosystems. Here are some benefits they provide:

  1. Natural Pest Control: Possums and opossums consume various insects, including garden pests such as slugs, snails, beetles, and even rodents. Their appetite for these pests helps maintain a balanced ecosystem and reduces the need for chemical pesticides.
  2. Seed Dispersal: Possums and opossums unknowingly contribute to seed dispersal by consuming fruits and berries. As they move through the garden, the seeds pass through their digestive system and are deposited in different locations, aiding in the natural regeneration of plants.
  3. Nutrient Cycling: Possums and opossums play a role in nutrient cycling by consuming fallen fruits, leaves, and decaying plant matter. Through their digestion and subsequent excretion, they enrich the soil with nutrient-rich feces, which benefits the overall health and fertility of the garden.
  4. Pollination: Possums and opossums can inadvertently assist in pollination while feeding on nectar-rich flowers. As they move from flower to flower, they may transfer pollen, aiding in the reproduction of plant species.

Coexistence and Garden Management

While possums and opossums can bring benefits to gardens, it’s important to maintain a balanced environment. Here are some tips for coexistence and garden management:

  1. Provide Natural Habitat: Create sheltered areas in your garden, such as nesting boxes or dense vegetation, to offer possums and opossums safe spaces to rest and raise their young.
  2. Protect Vulnerable Plants: If certain plants are particularly vulnerable to browsing, consider using protective barriers or fencing to prevent damage while still allowing these creatures access to other parts of the garden.
  3. Avoid Chemicals: Minimize chemical pesticides and herbicides that can harm possums, opossums, and other beneficial wildlife. Instead, explore organic and environmentally friendly pest control methods that maintain a healthy ecosystem.

Possums and opossums may differ in geography and behavior, but both contribute positively to gardens. Their role in natural pest control, seed dispersal, nutrient cycling, and even unintentional pollination highlights their value as garden allies. Understanding and appreciating these unique creatures can create harmonious garden ecosystems that benefit plants and wildlife.

If you do need to remove these critters from your garden for any reason, always use humane catch-and-release traps.
