Opossum sighting in Mount Vernon, New York. They are rarely seen because they are nocturnal. They are the only species of marsupial in North America. This photo was taken only a few miles north of New York City – New York City has opossums too. They are generally harmless.

The opossum has to be one of the ugliest (and nastiest) creatures in North America!
I think armadillos are much uglier. They can even spread leprosy to humans – http://www.cnn.com/2011/HEALTH/04/27/armadillos.spreading.leprosy/index.html
