largest possum

2 min read 28-02-2025

Possums, those often misunderstood marsupials, come in a surprising array of sizes and species. While many picture the small, rat-like creatures, the title of "largest possum" belongs to a much more impressive animal: the **common brushtail possum** ( *Trichosurus vulpecula*). While not the heaviest possum overall, its size and widespread distribution make it a strong contender for the title.

Debunking the Size Myth: What Makes a Possum "Large"?

Defining the "largest possum" isn't straightforward. There's no single metric – weight, length, or even head-to-body ratio – universally used to crown a champion. Some species, like the **cuscus** family (Phalangeridae), boast impressive weight, while others, such as the brushtail possum, can reach significant lengths.

To address this, we'll consider several factors: maximum recorded size, average size compared to other possum species, and geographic distribution. By combining these, we can present a compelling case for the common brushtail possum’s claim to the title.

The Common Brushtail Possum: A Giant Among Possums

The common brushtail possum, found across Australia and even introduced to New Zealand, is renowned for its adaptability and size. Mature males can reach a head-body length of up to 58cm (23 inches), with a tail adding another 30-40cm (12-16 inches). Their weight can reach up to 4.5kg (10 lbs), though averages are usually lower.

Size Comparison to Other Possum Species:

Cuscus: Certain cuscus species, such as the **lumholtz's tree-kangaroo** ( *Dendrolagus lumholtzi*) are heavier than brushtail possums. However, these are generally categorized separately from typical possums.
Ringtail Possums: Various ringtail possum species are significantly smaller than brushtail possums.
Virginia Opossum: The Virginia opossum ( *Didelphis virginiana*), found in North America, is another large possum species, but typically smaller than the largest brushtail possums.

Frequently Asked Questions about Large Possums

What is the heaviest possum species?

While the common brushtail possum often achieves impressive lengths, some cuscus species, specifically larger arboreal possums in the Phalangeridae family, can outweigh them. Determining the absolute heaviest requires more comprehensive data across various species.

Where are the largest possums found?

The largest brushtail possums are most commonly found in Australia. Their size can vary slightly depending on geographic location and available resources.

Are brushtail possums dangerous?

Brushtail possums are generally not aggressive towards humans, unless they feel threatened. However, their size and sharp claws mean they can inflict a painful bite if cornered or handled improperly.

Conclusion: The Reigning King (for now)

While the title of "largest possum" remains open to some interpretation, the common brushtail possum emerges as a strong contender. Its impressive size, widespread distribution, and readily available data make a compelling case. Further research may reveal other contenders, but for now, the common brushtail possum reigns supreme in the kingdom of large possums.
