Short description
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 11; Mjukstrålar i analfenan: 7. Body spindle-shaped and subcylindrical, and head anteriorly compressed. Other diagnostic characters include scaleless abdomen, horizontally placed pectoral and pelvic fins, 35-36 scales along the lateral line series, dark brownish spots in the predorsal region and along the sides of the body, relatively bigger head, deeper body and smaller mouth; hump-like shape in the predorsal region of bigger specimens (Ref. 75068).
