The migrations of young loggerhead turtles take them into the relative safety of the open ocean where predators are less abundant than in coastal waters. Visit our corporate site. The results imply that the turtles’ brains are hard-wired from birth to navigate their migratory routes. A case in point: In Florida and elsewhere, a common conservation practice is to surround turtle nests on the beach with wire cages to protect the turtle eggs from predatory beach raccoons. For loggerheads in particular, studies have generally found longer dives in colder temperatures [ 29 , 32 , 46 ] and deeper dives in warmer temperatures [ 5 , 32 ].
