Allison, a rescued green sea turtle who has only one flipper, swims with the aid of a fin attached with neoprene, on April 8. Without the attached fin, Allison can only swim in circles. Sea Turtle Inc., a not-for-profit in South Padre Island, Texas, helped outfit the turtle with a black neoprene suit, with a carbon-fiber dorsal fin on the back, that allows her to swim with other turtles. Researchers think the five-year-old turtle lost a flipper in a shark attack, The Associated Press reports. (Eric Gay/AP Photo )
