A marine fish of the Alectoridae family in the order Aquilegia. It has a huge mouth and tine-like teeth, and devours fish, squid, octopus, shrimp, etc. The English names Lancetfish, Handsaw Fish, and Wolf Fish come from this shape and habit. The body is long and thin. The Japanese name comes from the fact that the flesh contains a lot of water. The dorsal fin covers almost the entire dorsal edge except for a part of the rear half where the adipose fin is located, is fan-shaped, and is two to three times the height of the body. The anal fin is located at the rear end of the dorsal fin and near the bottom of the adipose fin, and the pelvic fin is located forward of the center of the body.
