Virginia opossum

Didelphis virginiana

Also known as: opossum, possum

The only marsupial native to North America — and one of Staten Island's most-underappreciated ecological allies. Opossums eat thousands of ticks per individual per season, are highly resistant to rabies (rare among mammals), and serve as quiet pest-controllers in residential and park environments. Common across the borough, often misidentified as 'giant rats' and persecuted accordingly.

Scientific

Didelphis virginiana is a 4–14 lb marsupial — the only marsupial native to North America. Solitary, nocturnal, omnivorous: insects, small vertebrates, fruit, carrion, eggs, garbage. Lifespan only 2–4 years; reproductive output high to compensate. Notable resistance to rabies (low body temperature inhibits the virus). Famous “playing dead” defensive behavior is involuntary — a stress-induced catatonic state.

Recent research (peer-reviewed, multiple replications) has documented that opossums groom thousands of blacklegged ticks off themselves per season — making them disproportionately useful as tick-control allies in Lyme-endemic regions.

On Staten Island

Common across the borough — parks, residential yards, alleys, the Greenbelt edges. Often misidentified as oversized rats and persecuted; the species is harmless to humans and beneficial in tick suppression.
