This holiday marks the signing of the Convention on Wetlands, which was held in Ramsar, Iran in 1971, and recognizes the importance of wetlands for the greater environment. It was first celebrated in 1997, and each year, a certain groundhog steals this holiday's thunder, thanks to coinciding with Groundhog Day on February 2. But never fear: In 2008, Ohio State University introduced the world to Olentangy Olga, the muskrat. This wetland dweller became a "new symbolic mammal" but hasn't quite been elevated to Punxsutawney Phil status yet.
