Enlarge By Eric Gay, AP Allison, a rescued green sea turtle with only one flipper, swims with the aid of a newly designed neoprene ninja suit in South Padre Island, Texas Wednesday. SOUTH PADRE ISLAND, Texas (AP)  Turtle rescuers have demonstrated the first fin suit designed to allow a green sea turtle that lost three of its flippers to finally swim a straight line. Workers at Sea Turtle Inc. strapped Allison, a five-year-old rescued turtle, on Wednesday into a neoprene "ninja" suit that holds a carbon-fiber fin in place on her back. The fin acts as a rudder, allowing her to propel herself forward with her sole fin. The success follows failed attempts last year to fit her with a prosthetic rear flipper. Before today, Allison could only swim in tight circles with her one good flipper. Copyright 2009 The Associated Press. All rights reserved.
