What adaptations help opossum survive?

Cool morphological adaptations! Opossums have opposable “thumbs” (halux) on their back feet, giving these critters agile climbing skills, and they have prehensile tails – meaning it acts as an extra hand –used for tasks like carrying nest-building material to helping them climb and/or hang from trees!

How do opossum survive in the winter?

Opossums have the most difficult winters of all. They rarely share a nest with other opossums. They will spend the winter in dens like abandoned woodchuck burrows, hollow trees and brush piles.

What is the conservation status of the opossum?
