The loggerhead sea turtle is a large marine turtle known for its distinctive heart-shaped shell and strong jaws. They can weigh up to 350 pounds and are found in oceans around the world, particularly in warm waters. Loggerheads primarily feed on jellyfish, conchs, and crustaceans, using their powerful beaks to crush hard-shelled prey. These turtles are classified as endangered due to threats like habitat loss, pollution, and entanglement in fishing gear. Loggerhead sea turtles are also known for their long migrations, often traveling thousands of miles between feeding and nesting sites, which are typically located on sandy beaches.
