What Is an Opossum? A Guide to North America's Only Marsupial

The Virginia Opossum, commonly known simply as "opossum," is a fascinating mammal found throughout North America. Unlike other mammals you might encounter in your backyard, opossums are marsupials, meaning they often carry their young in a pouch.

Key Opossum Characteristics

Size and Appearance

They are typically the size of a large house cat, with a pointed face, white fur, and a long, prehensile tail that they can use to grip branches.

Playing 'Possum'

When threatened, opossums are famous for "playing 'possum," where they feign death. This is an involuntary response to extreme fear.

Nocturnal Habits

Opossums are most active at night, which is when they forage for food.

Habitat and Diet

Opossums are highly adaptable and can live in a variety of environments, including forests, farmlands, and urban areas. They are omnivores and eat a wide range of foods.

What Do Opossums Eat?

• Insects, snails, slugs, and a significant number of ticks, which helps control tick populations.
• Small rodents and carrion (dead animals).
• Fruits, nuts, and grains.

Are Opossums Dangerous?

General Temperament

Generally, opossums are not aggressive and prefer to avoid conflict. While they might hiss or show their 50 teeth when cornered, they are very unlikely to attack humans or pets.

Rabies Risk

They also have a remarkable resistance to rabies due to their low body temperature, making them less of a threat than other wildlife.

Potential for Damage

However, if they take up residence in your attic, garage, or under your porch, they can cause significant damage and create a mess.
