To celebrate the 40th anniversary of the Marine Mammal Protection Act, a unique “Crimes Against Marine Mammals” exhibit runs through September 3, 2012 at the Crime Museum in Washington D.C.
The Marine Mammal Protection Act was passed in 1972 and prohibits, with certain exceptions, the take of marine mammals in U.S. waters or by U.S. citizens on the high seas, and the importation of marine mammals and marine mammal products into the U.S.
