The Virginia possum spends most of its time on the ground and climbs trees occasionally, while the bushtail possums in Australia live high up in trees; the confusion between the two species was caused by Joseph Banks in the 1770s.

Possums have a hard time surviving in cold weather, but their range has expanded as humans have moved further north and provided them with warm places to live in the colder months.

Possums have a forked penis and one of the smallest brain to body ratios in mammals, but they are surprisingly intelligent and perform well in tests involving food.

Possums are found in various habitats, including dense forests and cities, and they have a diverse diet that includes mammals, worms, insects, birds, reptiles, seeds, fruits, and garbage; they are often unfairly blamed for knocking over garbage cans, but they are actually just scavenging after other animals, and if you see a possum during the day, it does not mean it's rabid, as they can find food anytime and are unlikely to catch or transfer rabies; possums are clean animals and are great to have around because they eat ticks, critters, vermin, slugs, beetles, rotten fruit, and carrion, making them nature's sanitary engineers.

Possums can travel up to 15 miles in a few weeks, but keeping them as pets is not recommended because they need a lot of exercise; they gather twigs and leaves using their opposable thumbs and carry them to their dens using their tail; possums can hang from their tails, but they do not sleep upside down like bats; possums have short lifespans of about 2 years in the wild and have large litters, but not all babies are able to be fed by the mother.

Possums are born with a sense of smell and gravity, allowing them to climb upward and latch onto a nipple in their mother's pouch; they make quiet sounds like clicks and hisses, and when threatened, they may play dead as a last resort, but they are actually bluffing and just want to be left alone.

Possums are highly resistant to snake venom and have a special protein that encapsulates and deactivates the venom when it enters their bloodstream, which may be a potential cure for snake bites.
