dragonfish (cryptid)
The dragonfish (龍魚) "ryuugyo" is a Japanese cryptid fish with many whiskers and no bones. They were likely to have derived from misidentified sturgeon.
It is associated with Kasuga Ichiban from the Ryuu ga Gotoku series.
Not to be confused with the real world deep sea black dragonfish, nor the arowana which shares the same spelling in Chinese.
