Diagnosis: Virginia opossums have long flat skinny snouts and hairless ears. They have long hairless prehensile tails that can grab objects such as branches. The fur on their body is gray and their face fur is white. Their back feet have opposable thumbs. They average about 76 cm from their nose to their tail.

Natural History: Opossums are known for their defense mechanism of playing dead when threatened. They are the only marsupials found in the US or Canada. Females give birth to very small young that then crawl into her pouch where they continue developing. They stay primarily in the pouch or on their mother’s back until they are weaned after about 100 days.
