Leatherback sea turtle nesting in Mexico, Panama, El Salvador, Nicaragua, and Costa Rica. The continental United States offers two major Pacific leatherback feeding areas. One well-studied area is just off the northwestern coast near the mouth of the Columbia River. The other American area is located in California. Further north, off the Pacific coast of Canada, leatherbacks visit the beaches of British Columbia.

A third possible Pacific subpopulation has been proposed, those that nest in Malaysia. This subpopulation, however, has effectively
Loggerhead Key done to provide the monkeys a place to breed, to supply the animals for medical research laboratory experiments. Around 1,322 of the monkeys existed on the island between 1987–1990. The Dry Tortugas Light is a lighthouse located on Loggerhead Key. It began operations in 1858 and was decommissioned in 2014. The Carnegie Marine Biological Laboratory, also referred to as the Tortugas Laboratory, was a marine biology laboratory and research facility constructed on the northern end of Loggerhead Key that operated from 1904 to 1939. It was constructed and operated by the Carnegie Institution of Washington. The Carnegie Marine Biological Laboratory
