Korte beschrijving Morfologie | Morfometrie

Dorsale zachte stralen (totaal): 17-20; Anale zachte stralen: 18 - 21; Wervels: 52 - 54. Head relatively short, <39.5-0.025% SL. Snout short (22-28%HL); broadly triangular anteriorly when viewed from above. Orbit diameter about 1/5 to 1/4 HL, along the whole upper edge and on the separate elongate-shaped part of the lower-posterior part of the orbit are accumulation s of whitish connective tissue. Interorbital space very wide, ca. 17-30% HL, flat, narrows very slightly at the middle of the orbit. Upper jaw extends to below the center of the orbit. Branchiostegal rays 8-9. Transverse rows of scales above lateral line 60-65, 30-35 predorsal. Gill rakers' length less than gill lamellae length, and completely free at the base. Opercle has a projection at the lower anterior corner; subopercle has a wide posterior edge usually with no separate processes. Anus not shifted forward from the origin of the anal fin. Pyloric caeca 12-18 (Ref. 41471).
