The loggerhead sea turtle inhabit continental shelves, bays, lagoons, and estuaries in temperate and tropical waters around the world. They have large heads and crushing jaws, which they use for feeding on mollusk and crustaceans. Hatchlings are two inches long and adult loggerheads weigh between 200 and 350 pounds and measure up to three feet in length. In the United States, loggerhead nesting occurs on Florida beaches and to a lesser extent in South Carolina, Georgia, and North Carolina. The loggerhead sea turtle was listed at a threatened species in 1978. One of the chief threats to loggerhead turtles continues to be incidental capture in fishing activities.
