Short description
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 277 - 278; Mjukstrålar i analfenan: 252; Ryggkotor: 118 - 124. This species is distinguished by the following characters: trunk relatively long, about half of HL; anal-fin origin more than twice pectoral-fin length behind the tip of pectoral fin; pectoral fin is well developed; dorsal-fin origin over or slightly in front of base of pectoral fin; two intermaxillary teeth; four or five compound teeth on ethmovomer; single row of seven or eight teeth on the lower jaw; total lateral-line pores 70-76; vertebrae in pre-anal 21 and total 118-124 (Ref. 131161).
