Caretta

Caretta is a genus of sea turtles in the family Cheloniidae containing a single living species, the loggerhead sea turtle, named for its large head, with a skull distinguished from other sea turtles by maxillae that meet at the midline of the palate. It has a cosmopolitan distribution nesting over the broadest geographical range of any sea turtle, inhabiting the Atlantic, Indian and Pacific Oceans and the Mediterranean Sea, and is the largest hard-shelled turtle in the world, with adults averaging around 135 kilograms and about 90 centimeters in carapace length.
