Body oblong, oval, compressed. Scales ctenoid; lateralline scales not enlarged; cheeks and operculum scaly.
Preopercle serrate, but no single large spine; opercle with
low ridge or keel ending in a spine; 2 supramaxillae. Dorsal
fin with 4-7 closely set spines and 12-20 branched soft-rays.
Anal fin with 4 spines and 12 to 30 branched soft-rays; pelvic

Berycids are found worldwide (but not in eastern Pacific
Ocean) in depths of 200 - 600 m; they are of commercial
importance in some areas. Two genera with 7 species.

Genus Beryx Cuvier, 1829
Dorsal-fin spines 4; V fins 1,10-12. Inner surface of each
scale with a small, deciduous, cartilaginous disc at rear
