Goldfishキンギョ
Carassius auratusNE— Not Evaluated
The goldfish is one of the world's oldest domesticated ornamental fish, bred in China over a thousand years ago from mutant crucian carp and later refined into hundreds of color and body-shape varieties. Hardy and highly adaptable, it can live over a decade in captivity, has been shown to retain memories for months, and has even traveled to space as a research subject.

Did You Know?
- Goldfish are tetraploid, carrying doubled sets of chromosomes, which makes them prone to genetic variation—one reason centuries of breeding have produced hundreds of distinct color and body-shape varieties. Source
- Goldfish are tetrachromats, possessing four types of cone cells that let them perceive red, green, blue, and even ultraviolet light, and research shows they retain memories for at least three months and can distinguish shapes, colors, and sounds. Source
- In July 1994, six goldfish from Yatomi, Aichi Prefecture, flew aboard the Space Shuttle Columbia as experimental animals studying behavior in microgravity. Source
