A Japanese dolphin is squealing with delight after receiving a prosthetic tail to replace one amputated due to a skin disease. Fuji's handlers at the Churaumi Aquarium in Japan's southern most island of Okinawa say the fake tail may have saved her life as she had put on dangerous amounts of weight from being inactive after she lost her tail. "Because she was not exercising enough (after her tail was amputated) she gained weight and from blood samples we took we realized that her cholesterol levels were too high. We then were afraid that this might trigger other diseases so we had to come up with something," handler Masaya Koami said. The tail was custom made for Fuji by a friend of the handler who works at Japan's leading tire company Bridgestone. The rubber prosthetic device is slightly smaller than the tail of a dolphin of Fuji's size. It is made of material used for Formula One race car tires and the black silicon rubber was reinforced with artificial bone made of carbon-fiber. Sponge rubber was used for parts that come directly in contact with Fuji's skin. Bridgestone said they spent at least 10 million yen (about $83,000) to develop and produce the fin. As for Fuji, the freedom that it brought her is priceless. After initially being frightened of it, the dolphin now leaps and swims with vigor.

The world's tallest man saved two dolphins in northeast China by reaching inside of them with his 3-foot arms to remove plastic they had swallowed.

The dolphins got sick after eating plastic from the edge of their pool at an aquarium in Liaoning province. Attempts to use surgical instruments to remove the plastic failed because the dolphins' stomachs contracted in response to the instruments, the China Daily newspaper reported.

Veterinarians than decided to ask for help from Bao Xishun, a 7-foot-9-inch inch herdsman from Inner Mongolia.

Chen Lujun, the manager of the Royal Jidi Ocean World aquarium, told The Associated Press that the shape of the dolphins' stomachs made it difficult to push an instrument very far in without hurting the animals. People with shorter arms could not reach the plastic, he said.

"When we failed to get the objects out we sought the help of Bao Xishun from Inner Mongolia and he did it successfully yesterday," Chen said. "The two dolphins are in very good condition now."

Bao, 54, was confirmed last year by the Guinness Book of World Records as the world's tallest living man.Photographs showed the jaws of one of the dolphins being held back by towels so Bao, who has 41.7-inch arms, could reach inside the animal without being bitten.

"Some very small plastic pieces are still left in the dolphins' stomachs," Zhu Xiaoling, a local doctor, told Xinhua. "However the dolphins will be able to digest these and are expected to recover soon."
