On Friday, U.S. Customs and Border Protection officials at the Detroit Metropolitan Airport made an unusual discovery when an X-ray screening revealed a skull-shaped object in an unaccompanied piece of luggage. Upon further examination, it was determined to be the skull of a young dolphin. The US Fish and Wildlife Service is responsible for enforcing the laws and regulations that protect endangered species, and this discovery serves as a reminder of the importance of protecting these species and the laws that are in place to do so.
