Richardson's dragonet; Richard's dragonet
A species of dragonet (Repomucenus richardsonii) found in Japanese waters. The name is a fish name and is usually written in katakana.
The Richardson's dragonet is a demersal fish that lives on sandy-muddy bottoms.
Usually written in katakana as a fish name; the kanji form 鼠鯒 is rare.
Rare kanji form; the second character 鯒 is not a standard Jōyō kanji.
Compound of 鼠 (nezumi, 'mouse, rat') and 鯒 (gochi, 'flathead'). The name likely refers to the fish's somewhat mouse-like appearance or behavior, but the exact derivation is uncertain.
