According to the National Oceanic and Atmospheric Administration, dealer Gregory Logan of Alberta, Canada, sold more than 400 narwhal tusks to buyers across the U.S. between 2003 and 2010. He has active arrest warrants in the United States in connection with the case, which has so far seen the arrests of three people accused of illegal trafficking of tusks from Canada to the United States. Under the Marine Mammal Protection Act, it is illegal to transport, purchase, sell, or export (or offer to do so) any marine mammal or marine mammal product, unless the intention is public display, scientific research, or enhancing the survival of a species.
