Turtles are nomads of the sea, able to navigate over long distances and still find their way home.
By Dr. Sylvia Earle From American Samoa to Hawaii in the Pacific, from the Gulf of Mexico to the Florida Keys to Gray's Reef in the Atlantic, and throughout all warm seas beyond, certain familiar faces reappear. Among them are the five main kinds of turtles, who range the world's warm oceans much as globe-trotting humans range over many lands. Some travel over a quarter of the planet while riding ocean currents. We still don't know. What is known for sure is that nothing in the long and durable history of turtles has prepared them for the ways we now threaten their existence.
