Green sea turtle hatchling in the ocean
  It is believed that sea turtle hatchlings, such as this green sea turtle, locate the ocean because they are phototactic - they are attracted to light. At night, without any man-made lights to confuse them, the glow from the ocean reflects the brightest ambient light. Sea turtle hatchlings will avoid dark areas, such as the dune, as this is the area where predators abound. Learn more about sea turtle navigation.
