The Loggerhead turtle is the most frequently encountered sea turtle in the Mediterranean. It is easily recognised by its reddish-brown, heart-shaped shell and pale-yellow underside. Its name comes from its notably large head and powerful jaws, perfectly adapted for crushing hard-shelled prey such as crabs and conchs. Loggerheads are also known to feed on jellyfish.

Found in temperate to tropical oceans worldwide, Loggerhead turtles are exceptional long-distance migrants, particularly during the nesting season. Producing eggs requires enormous energy, so females typically reproduce every two to three years. During a single nesting season—usually between May and August—a female may lay up to five clutches of eggs at intervals of around two weeks. Each clutch can contain as many as 115 eggs.
