* Teeth: They have 50 teeth, more than any other North American mammal. These teeth are sharp and pointed, adapted for their omnivorous diet, which includes insects, fruit, and small animals.
* Claws: Opossums have sharp claws on their paws that help them climb trees and dig. They are also used for defense.
However, opossums are not aggressive animals. They are more likely to play dead when threatened than to attack.
