| The Pacific rudderfish (Psenopsis anomala) is a marine fish also known by such names as Japanese butterfish, melon seed, wart perch, ibodai (Japanese name, イボダイ) or simply but ambiguously as butterfish.[1][2] This fish, which can grow to 30 cm (12 in) TL, is found in the Western Pacific, near Japan, in the Taiwan Strait and in the East China Sea. The Japanese butterfish prefers tropical waters: around 42°N–19°N. It has been found in the waters near Hong Kong. Generally, they inhabit the epipelagic layer to 370 m (1213 ft). Adults are mainly bottom-dwelling, but migrate upward at night in search of food.[2] |
