Opossums are marsupials native to the Americas, known for their unique ability to play dead when threatened. They have a pointed snout, large ears, and a long, hairless tail. Opossums are nocturnal and primarily feed on insects, fruits, and small animals, helping control pest populations. These animals are also notable for their low body temperature, which makes them less susceptible to diseases like rabies. Opossums are the only marsupials found in the United States and are often recognized by their grayish fur and distinctive appearance. They play an important role in their ecosystems as scavengers.
