Virginia Opossum
By Lindsay Rogers
Didelphis virginiana
As North America's only marsupial,
Virginia opossums give birth to
drastically underdeveloped young
which are about the size of a grape.
These nearly helpless young
have surprisingly strong front legs
which allow them to crawl into their
mother's pouch. If they safely make
the journey into the pouch, the young will continue to grow and develop for another 3-4 months.
Historically Virginia opossums were found in Central America north to the southern and southeastern
United States. With the increase of human populations and changing climate, they have increased their
range which now extends into Canada. Individuals in more northern climates often seek shelter in
buildings. Additionally, their hairless ears and tails often show signs of frostbite.
Contrary to popular belief, "playing 'possum" is rare and typically seen in young adults. More often,
opossums become aggressive or simply flee when faced with danger. ■
