Why Are They Called Possums? A Deep Dive into the Naming of North America’s Marsupial
The name possum is a fascinating tale of mistaken identity, originating from Captain John Smith’s encounter with the didelphimorphia of North America, who incorrectly identified them with the opossums of South America. This article unpacks the history, linguistic roots, and scientific accuracy behind the question: Why are they called possums?
The Great Confusion: Opossums vs. Possums
The story behind the name “possum” is rooted in a historical case of mistaken identity and linguistic evolution. When European explorers first encountered the animals now known as Virginia opossums in North America, they were struck by their resemblance to the opossums they had seen in South America. Captain John Smith, a prominent figure in the Jamestown settlement, is credited with being among the first to record the name “opossum” for the North American marsupial. He was unaware that they were different enough to deserve different names.
Linguistic Origins: Algonquian Roots
Both “opossum” and “possum” derive from the Algonquian word wapathemwa, meaning “white animal.” This makes sense when you see a Virginia opossum, with their distinct coloring. Over time, “wapathemwa” was Anglicized to “opossum,” and later shortened to “possum” in common usage, particularly in certain regions of the United States. It’s important to note that the word opossum, and its later derivative possum, does not describe any single animal. Both words describe an entire order of animals.
The Importance of Scientific Accuracy
While the terms are often used interchangeably, especially in casual conversation, it’s crucial to understand the scientific distinction between opossums and possums. The term “opossum” technically refers to members of the family Didelphidae, found primarily in the Americas. “Possum” is commonly used to refer to members of the suborder Phalangeriformes, marsupials native to Australia, New Guinea, and Sulawesi.
The North American marsupial is therefore correctly referred to as an opossum, but the shortened form possum has become deeply ingrained in popular culture and regional dialects. In Australia, it is incorrect to use the term “opossum” instead of “possum”.
Regional Variations in Usage
The use of “possum” versus “opossum” varies considerably by region. In the Southern United States, “possum” is the more common term for the North American marsupial. In other parts of the country, and in more formal contexts, “opossum” is preferred. Interestingly, if someone asks Why are they called possums? the answer may be different for an Australian than it is for someone from the Southern United States.
Conservation Status and Misconceptions
Both opossums and possums play important roles in their respective ecosystems. North American opossums are often misunderstood and even feared, but they are actually beneficial creatures, acting as natural pest control by consuming insects, rodents, and even snakes. They are also surprisingly resistant to rabies. Similarly, Australian possums play crucial roles in seed dispersal and pollination. Understanding these animals and their importance is vital for conservation efforts.
Understanding the Etymological Shift
The abbreviation of “opossum” to “possum” is a prime example of linguistic simplification. As languages evolve, words often get shortened or altered for ease of pronunciation and everyday use. This trend is particularly evident in informal settings and regional dialects, where tradition and convenience often outweigh strict adherence to etymological correctness. While “opossum” is more technically precise, “possum” continues to thrive, showcasing the dynamic nature of language.

Frequently Asked Questions (FAQs)
Are opossums and possums the same animal?
No, opossums and possums are not the same animal. While both are marsupials, they belong to different scientific families and are native to different continents. “Opossums” are found primarily in the Americas, while “possums” are native to Australia, New Guinea, and Sulawesi.
Why do some people call opossums “possums”?
The use of “possum” as a shortened form of “opossum” is a result of linguistic simplification and historical usage. Captain John Smith was mistaken in his classification of them. It’s particularly common in certain regions, such as the Southern United States, where “possum” has become the accepted vernacular.
Is it incorrect to call an opossum a “possum”?
From a strictly scientific perspective, it is more accurate to use the term “opossum” when referring to the North American marsupial. However, the usage of “possum” is so deeply ingrained in certain cultures and regions that it’s generally accepted in informal settings.
What is the scientific name for the Virginia opossum?
The scientific name for the Virginia opossum, the most common species in North America, is Didelphis virginiana. This name distinguishes it from other marsupials around the world.
Do opossums play dead?
Yes, opossums are famous for their defense mechanism of playing dead, also known as “playing possum.” When threatened, they can feign death, emitting a foul odor and becoming limp, which often deters predators.
Are opossums dangerous to humans?
Opossums are generally not aggressive towards humans. They are more likely to run away or play dead if they feel threatened. However, like any wild animal, they can bite if cornered or provoked.
What do opossums eat?
Opossums are omnivores, meaning they eat a wide variety of foods. Their diet includes insects, rodents, fruits, vegetables, eggs, and even carrion. This dietary flexibility makes them well-adapted to various environments.
Are opossums related to kangaroos?
Both opossums and kangaroos are marsupials, but they belong to different orders. Kangaroos are part of the order Diprotodontia, while opossums belong to the order Didelphimorphia. So, while they share a common ancestor, they are not closely related.
How long do opossums live?
The lifespan of an opossum is relatively short, typically only 1-2 years in the wild. This is due to various factors, including predation, disease, and road accidents.
Do opossums carry diseases?
Opossums can carry certain diseases, such as leptospirosis, tuberculosis, and coccidiosis. However, they are remarkably resistant to rabies, and they are not considered a major carrier of the disease.
How can I help protect opossums?
You can help protect opossums by keeping your yard clean and free of trash, driving cautiously at night, and avoiding the use of poison to control pests. Supporting wildlife rehabilitation centers can also make a significant difference.
Why are opossums important to the ecosystem?
Opossums play a crucial role in the ecosystem as natural pest control agents. They consume large numbers of insects, rodents, and carrion, helping to keep these populations in check and preventing the spread of disease. Their scavenging habits contribute to a cleaner environment. Answering the question Why are they called possums? may seem simple, but it touches on important scientific principles of ecology.
