Didelphis virginiana
North America’s familiar marsupial, recognizable by a pale face and nearly bare tail.

Long, pointed muzzle with a pale face and dark eyes
Small, rounded, nearly hairless ears
Coarse gray-brown coat and a long, scaly, prehensile tail
Woodland edges, thickets near water, farms, suburbs, and city green space where shelter and food are available.
A slow-moving, solitary night forager. When severely stressed, an opossum may enter an involuntary catatonic state known as ‘playing possum.’
Raccoons have a black mask and a thick ringed tail. Domestic rats are far smaller and lack the opossum’s pale face and coarse body fur.
Give it a clear escape route and bring pets indoors. An opossum that appears motionless may recover once the threat has passed.
Do not handle wildlife. Use gloves and local animal-control guidance if an opossum is trapped or injured.
Virginia opossums coexist well with people and are not considered threatened or endangered in the United States.
