Fuji, a female bottlenose dolphin, swims using its artificial tail at Okinawa Churaumi Aquarium in Motobu town, on the southern Japanese island of Okinawa July 8, 2007. Fuji, which lost 75 percent of its tail due to an unknown disease in 2002, can swim faster and jump higher using the artificial rubber tail, which is believed to be the world's first artificial fin for a dolphin, an aquarium official said.
