Possum vs Opossum: Understanding the Differences


Possums and opossums are distinct creatures that often confuse due to their similar names. Despite their shared name and some physical resemblances, possums and opossums are different animals. This article will explore the differences between possums and opossums, shedding light on their unique characteristics and habitats. By the end of this article, you will have a clear understanding of these fascinating creatures and be able to differentiate between the two.


Let’s start with possums. Possums are marsupials native to Australia, New Guinea, and nearby islands. They belong to the family Phalangeridae and are known for their diverse species and adaptations to different environments. Possums have a prehensile tail, which means they can grasp and hold onto branches, aiding their arboreal lifestyle. They also have sharp claws that enable them to climb trees with ease.

Possums come in various sizes and appearances, with some species having a bushy tail while others have a more slender tail. They have adapted to different habitats, including forests, woodlands, and urban areas. Regarding diet, possums are omnivorous, feeding on various food sources such as fruits, leaves, nectar, insects, and small vertebrates.


Now let’s turn our attention to opossums. Opossums, scientifically known as Didelphidae, are marsupials found primarily in the Americas. Unlike possums, opossums are more commonly encountered in North and South America. They are known for their distinct appearance, characterized by a long, hairless tail and a pointed snout. Opossums are primarily ground-dwelling creatures, although they are also capable climbers.

Opossums have a wide-ranging diet and are opportunistic feeders. They are known to consume fruits, insects, small animals, carrion, and even garbage. Opossums are also famous for their “playing dead” defense mechanism, where they feign death as a strategy to deter predators.

 Possums Vs Opossums: Differences

To summarize, here are the key differences between possums and opossums:

Taxonomy and Scientific Classification:

  1. Possums and opossums are classified under different orders and families. Possums belong to the order Diprotodontia and are native to Australia, New Guinea, and Sulawesi. On the other hand, opossums fall under the order Didelphimorphia and are found in the Americas, particularly in North and South America.

Physical Characteristics:

  1. Possums and opossums have similarities in appearance, such as their small size, furry bodies, and long tails. However, there are notable distinctions:
  • Possums: Possums have a diverse range of species, but in general, they have rounder ears, pointy snouts, and prehensile tails, which means they can grasp and hold onto branches. Their fur can vary in colour, from grey to brown, and they typically have a pouch where they carry and nurse their young.
  • Opossums: Opossums have a more rat-like appearance, with hairless, pointy ears and a long, narrow snout. They have a unique adaptation called a prehensile tail, which can curl and grip objects but is not as strong as that of possums. Opossums are known for their hairless, scaly tails and opposable, clawless thumbs on their hind feet.

Habitat and Distribution:

  1. Possums and opossums inhabit different parts of the world:
  • Possums: Possums are predominantly found in Australia, where they have adapted to various habitats, including forests, woodlands, and urban areas. They are also present in New Guinea and Sulawesi. The most well-known species is the common brushtail possum, which has successfully adapted to urban environments and can be found in cities and suburban areas.
  • Opossums: Opossums are native to the Americas and have a wide distribution across North and South America. They are highly adaptable and can thrive in a range of environments, from forests and swamps to urban areas. The Virginia opossum is the most common species in North America.

Behaviour and Diet:

  1. Both possum and opossum are primarily nocturnal animals, but their behavior and dietary preferences differ:
  • Possums: Possums are arboreal creatures, meaning they spend most of their time in trees. They are excellent climbers and have sharp claws for gripping branches. Their diet consists of fruits, leaves, nectar, insects, and occasionally small vertebrates. Possums are also known for their ability to play dead when threatened, a behavior known as “playing possum.”
  • Opossums: Opossums are more opportunistic and omnivorous in their feeding habits. They are scavengers and will consume a variety of food, including fruits, insects, small animals, carrion, and even garbage. Opossums are known for their ability to eat almost anything and can play a valuable role in controlling pests.

Reproduction and Lifespan:

  1. The reproductive cycles of possums and opossums also differ:
  • Possums: Possums have a shorter gestation period and give birth to relatively undeveloped young, which then crawl into the mother’s pouch and continue to develop. The young possums are called Joeys. The average lifespan of possums is around 2 to 4 years in the wild.
  • Opossums: Opossums have a longer gestation period, and the newborns are tiny and underdeveloped, roughly the size of a honeybee. They immediately crawl into the mother’s pouch, where they continue to develop. Opossums have a shorter lifespan than possums, typically living up to 2 to 4 years in the wild.


In summary, although possums and opossum may sound similar and share certain physical attributes, they are distinct animals with unique characteristics. Possums are native to Australia, while opossums are found in the Americas. Possums are tree-dwelling, have rounder ears, and possess prehensile tails, while opossums have hairless tails, opposable thumbs, and rat-like features. Understanding the differences between these fascinating marsupials helps us appreciate their diverse adaptations and ecological roles in their respective habitats.
