Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 14 - 15; Mjukstrålar i ryggfenan (totalt) : 10 - 11; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 8 - 10. Diagnosis: rather deep-bodied (40.0-47.0% SL), greatest depth well behind dorsal fin origin; head moderately large (length 34.0-37.2% SL); wide interorbital (33.5-41% HL); mouth terminal and small; jaws (specimens >60 mm SL) with outer row teeth evenly spaced conical, unicuspid, 2-4 rows of smaller unicuspid inner teeth; smaller individuals often with some shouldered unicuspid or bicuspid teeth in jaws; caudal peduncle short and deep (Ref. 81260). Soft dorsal and anal fins produced in adults, extending well over caudal fin in males (Ref. 52307, 81260). Caudal fin truncate and heavily scaled over base; 3.5-4 scales between upper lateral line and dorsal fin origin; lanceolate epibranchial rakers; tips of pelvic fins in males reach well beyond the spinous anal fin (Ref. 81260).
Open substratum spawner (Ref. 52307).
