A dolphin in a Japanese water park, who couldn't swim because it had no tail, has been given a new lease of life after being fitted with an artificial fin. Fuji, the 36-year-old bottlenose dolphin, suffered a life-threatening disease which caused her tail to rot four years ago. Rather than let the disease spread to the rest of her body, veterinarians at the Churaumi Aquarium in Okinawa, Japan, decided to amputate her tail fin. The result was a very depressed dolphin who could no longer frolic in the water with her aquatic pals. Having no tail also meant Fuji was unable to exercise. This meant she started putting on the kilos, which caused a further threat to her life. Just when doom and gloom surrounded the future of Fuji, in stepped an unlikely saviour the Japanese tyre manufacturer Bridgestone.
Bridgestone is more commonly associated with Formula One racing technology than artificial dolphin fins. However, it seems dolphin fins and racing car tyres have more in common than we believed. Bridgestone saved Fuji’s life by pouring around US$83,000 dollars into creating the replacement fin. The new prosthesis is made from the same kind of rubber that is used for Formula One car tyres. Fuji wears her new tail fitting for just two to three hours everyday. Her trainer hopes Bridgestone can make an improved version that can be worn for longer, as part of the new fin wears out quickly. This means Fuji will experience pain and discomfort if she uses the fin for a long time, and she’ll end up getting hurt. Her trainer said: "Thanks to the new prosthetic creation Fuji is now able to lead a normal life."
