|---|---|---|
| A. M. Prokofiev 2006 | Fish of small to medium size (up to 60 cm SL) with moderately elongated body. Snout com- pressed laterally. There are suborbitale and antorbitale. Two supramaxillaria. Maxillare broadened caudally, not reduced, not supported by infraorbitalia. Teeth on jaws small, conical, in multiple rows; small on the palatinum. There is posttemporal fossa. Horizontal branch of praeoperculum weakly shortened; suboper- culum larger than operculum. Branchiostegal rays 16–26. Gill rakers developed normally. Cleithrum attaches to the lower half of supracleithrum. Vertebrae 41–53. Cau- dal part of the vertebral column significantly shorter than the abdominal part. Intermuscular bones well developed. No hypural diastema in the caudal skeleton, there is a free ural vertebrae (u-2). Dorsal fin signifi- cantly deep, sometimes with elongated rays, contains 14–21 rays, its base has moderate length (less than half of the body length), begins in the anterior part of the body. Anal fin contains 9–13 rays. Pectoral fin forms an angle of 45° with the body. Pelvic fins significantly longer than pectoral. Scale cover well developed, no enlarged scales on the sides of the body and in the base of the caudal fin. There are fulcral scales in the base of the caudal fin. Photophores absent. Swimbladder and peritoneal pigment sections absent. Eye has no afocal zone. Bottom dwelling fish, inhabit moderately deep areas (up to 200 m). |
