Discover fascinating facts about opossums, including their unique biological traits, behaviors, and ecological roles. Learn about their immunity to venom, remarkable adaptability, and importance in controlling pests and ticks. Explore the intriguing world of North America’s only marsupial.
Opossums, North America’s only marsupials, boast several remarkable abilities, including immunity to snake venom and a high resistance to rabies. These nocturnal creatures play a crucial role in controlling insect and rodent populations, thanks to their omnivorous diet.
Additionally, opossums have a unique defense mechanism: when threatened, they can “play dead” by falling into a temporary catatonic state, deterring predators. Their prehensile tails and opposable thumbs on their hind feet aid in climbing and handling food, showcasing their adaptability and versatility in various environments.
