Opossum vs Possum

Despite their similar names and shared classification as marsupials, these creatures belong to different families and hail from distinct parts of the world. This confusion is compounded in North America, where the term “possum” is colloquially used to refer to the Virginia opossum, leading to widespread misunderstanding about these two distinct animals. This article aims to unravel the mystery, shedding light on the unique characteristics that set “opossums” and “possums” apart, from their physical attributes to their habitats and behaviors.

Opossums, North America’s sole native marsupials, boast a versatile diet and are known for their distinctive grayish fur, pointed snouts, and ability to carry their numerous young in a pouch. On the other side of the globe, Australia’s brushtail possums present a stark contrast with their bushy tails and more compact facial features. Understanding the differences between these marsupials not only enriches our knowledge of wildlife but also highlights the fascinating diversity of life that thrives across continents. Join us as we explore the intriguing distinctions between the opossum and the possum, enhancing our appreciation for the natural world’s complexity.

What are Opossums and Possums?

“Opossums”: Opossums refer to a group of marsupials native to the Americas, particularly known for the species commonly found in North America, the Virginia opossum (Didelphis virginiana). These creatures are characterized by their adaptable nature and omnivorous diet, consuming a wide range of food from fruits and insects to small animals. Opossums have a distinctive appearance with grayish-white fur, long pointed snouts, sharp teeth, and naked, prehensile tails. They are roughly the size of a domestic cat, with adults measuring about two to three feet in length. Unique among North American mammals, opossums have a pouch to carry and nurture their young, similar to kangaroos and other marsupials. Notably, opossums are known for “playing dead” as a defense mechanism against predators, a behavior called thanatosis. Opossums are solitary, nocturnal animals, often seen foraging for food at night.


“Possums”: Possums, on the other hand, are marsupials found primarily in Australia, with some species also in New Guinea and Sulawesi. The term “possum” is most commonly associated with the Phalangeriformes order, which includes various species such as the common brushtail possum (Trichosurus vulpecula) and the ringtail possum (Pseudocheirus peregrinus). Unlike opossums, possums have softer, fur-covered tails, and their snouts are shorter and less pointed. Possums vary in size depending on the species, with some being as small as a mouse and others as large as a cat. They are also predominantly arboreal, living in trees, and have a diet consisting mainly of leaves, fruits, and flowers. Possums are social animals compared to the solitary opossum and are known for their ability to adapt to urban environments, often seen dwelling in roof spaces of houses. Possums play a significant role in the ecosystem as pollinators and seed dispersers, contributing to the health of their habitats.


Opossums and possums, though commonly confused due to their similar-sounding names, are distinct marsupials belonging to different parts of the world and exhibiting unique characteristics. Opossums, particularly the Virginia opossum, are native to North America and are recognized for their grayish fur, pointed snouts, and prehensile tails. These nocturnal creatures are omnivorous, feeding on a varied diet that includes insects, fruits, and small animals. On the contrary, possums inhabit Australia and surrounding islands and are known for their softer, bushier tails and shorter snouts. They are primarily arboreal, living in trees, and have a diet that leans more towards leaves, flowers, and fruits. Possums are more social compared to opossums and have adapted well to urban environments, often found residing in human dwellings.

Difference Between Opossum vs Possum

The terms “opossum” and “possum” often lead to confusion, largely due to their phonetic similarity, yet they refer to distinct groups of marsupials native to different regions of the world. Opossums are found primarily in North America, with the Virginia opossum being the most recognized species in the United States. Possums, conversely, are native to Australia and surrounding islands, with species like the common brushtail possum and ringtail possum being well-known. Despite both being marsupials, their physical characteristics, habitats, and behaviors showcase notable differences. Understanding these distinctions is crucial for accurate identification and appreciation of their unique roles in their respective ecosystems. The following table elucidates ten key differences between opossums and possums:

Is a Possum and an Opossum the Same Thing?

No, a possum and an opossum are not the same. The term “opossum” refers to the marsupials found in North and South America, especially noted for the Virginia opossum. “Possum” points to a variety of marsupials native to Australia and its surrounding islands. Their similarities lie in being marsupials, but they belong to different families and continents.

Can Opossums Carry Rabies?

Opossums are less likely to carry rabies compared to other mammals. Their lower body temperature creates an inhospitable environment for the rabies virus. However, it’s still possible, albeit rare, for them to contract rabies. Caution and professional advice should be sought if an opossum bite occurs.

Why Is a Possum Not a Rodent?

A possum is not a rodent because it belongs to the marsupial family, which is characterized by giving birth to partially developed offspring that mature in a pouch. This distinguishes them significantly from rodents, which are placental mammals with different reproductive and physiological traits.

Is the O Silent in the Word Opossum?

Yes, in many regions, particularly in North America, the initial ‘o’ in “opossum” is often silent when pronounced, leading to the common pronunciation “possum.” However, the correct scientific and formal pronunciation includes the ‘o’. The pronunciation can vary based on regional dialects and contexts.
