The Living Jewels of Japan: Koi Fish

The mesmerizing aquatic creatures featured are Koi fish (Cyprinus rubrofuscus), a domesticated subspecies of the common carp. These ornamental fish are celebrated for their vivid and diverse coloration, which includes striking patterns of white, black, red, yellow, and cream. Each unique pattern has its own name and significance in Japanese culture, where Koi are symbols of luck, prosperity, and perseverance.

Unlike wild carp, which are a dull brownish color, Koi have been selectively bred for centuries to produce their spectacular appearance. They are often kept in outdoor ponds and are known for their longevity, with some individuals living for over a century. The serene movements and bright colors of Koi make them a popular sight in public gardens and private landscapes around the world, truly earning their nickname "living jewels."
