I take some issue with the statement in the link above that North America has only 2 species of endemic marsupials. If only the USA is considered and Mexico is relegated to Central America, then there is only one, the Virginia oppossum. If Mexico is included in North America then one would have to add to the list the southern oppossum, water oppossum, grayish mouse oppossum, Mexican mouse oppossum, Robinson's mouse oppossum, Central American wooly oppossum, and the gray 4-eyed oppossum (no it doesn't really have 4 eyes, just a couple of curiously placed spots)
