ST. CROIX - AUG 16: Turtle Researchers Amy Mackay and Richard Gideon check a newly affixed tag on a green turtle as she begins flnging sand to disguise her nest on the beach at East End Bay in St. Croix, U.S. Virgin. Islands on August 16, 2008. This does not hurt the turtle. This image shows the size of the body pit as well--dug by the powerful 2 front flippers. The 2 rear flippers dig down into the sand underneath the turtle, in order to make a hole in which she deposits the eggs. This photograph was made under the supervision of federally authorized researchers. (Photo by Landon Nordeman).
