Dolphin Jumps Again with Artificial Fin

Ant writes "This Yahoo! News story mentions Fuji, a mother dolphin that lost 75 percent of her tail due to a mysterious disease, being able to jump again with the help of what is believed to be the world's first artificial fin. The 34-year-old dolphin held at Japan's largest aquarium in the southern island of Okinawa wears the rubber fin for about 20 minutes a day allowing her to jump and to swim at the same speed of other dolphins."
