Caretta caretta (Linnaeus, 1758).

Carapace length up to 2130 mm. This turtle is distinguished by its massive head with powerful jaws; the carapace is elongated with margins that are serrated in adolescents; less but still distinct in adults. The color is dark brown sometimes with green or darker blotches. The Loggerhead Turtle is a marine turtle, but may also be found in estuaries, lagoons, and creeks. It is mainly carnivorous feeding on sponges, jellyfish, crabs and fish, and occasionally seaweeds and seagrasses. Typically, 4-5 clutches of eggs are laid per season at 2-3 year intervals; each clutch consists of 64-200 round parchment-shelled eggs, which takes an incubation period of 49-71 days. In Egyptian waters, it is found in the Mediterranean and rarely in the Red Sea. Globally, it is distributed through the Atlantic, Pacific, and Indian oceans, sometimes far north and south. In common with other marine turtles, it is endangered due to the loss of nesting habitat, hunting, and being caught in fishing nets.
