Once the turtles reach adulthood, their formidable size limits predation to large marine animals, such as sharks. The nesting season is short, between May and August in the Northern Hemisphere and between October and March in the Southern Hemisphere. Cold water upwelling around the Cape of Good Hope and reduction in water temperature at Cape Horn formed coldwater barriers to migrating turtles.
