Small sea turtles, especially post-hatchlings, do not survive the low winter water temperatures in the Sea of Japan. Most do not survive. The Earth’s magnetic field varies across the globe; slightly different fields exist in different geographic regions. Smart swimming enables turtles to conserve energy while migrating vast distances. Loggerhead Green Sea Turtle Each of these sea turtles has its own life cycle. The orientation apparatus. … Caretta caretta (Linnaeus, 1758) are commonly called “loggerhead” sea turtles due to their overly large heads with a horny beak that is significantly thicker than in other sea turtles.

The most recent reviews show that only two loggerhead nesting beaches have greater than 10,000 females nesting per year: South Florida and Oman. Well-meaning though the use of such cages may be, they may distort the local magnetic field and thereby compromise the ability of hatchlings to navigate after they leave their nests.
