9The Koi Fish

Usually, the domesticated variety of this common carp has a life expectancy of nearly 30 years. But yet again some of them outlive the others by centuries like the one huge golden carp in Japan which is 226 years old! The reason behind this is quite interesting. When Japan started exporting the koi fish abroad, the finest of the specimens never left the homeland. Also, the Japanese breeders feed them modestly and transfer them to larger earthen dams which allow them to grow stronger and bigger and avoid obesity which is the prime reason for their demise.
