🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 20; Anal spines: 0; Anal soft rays: 16 - 19; Vertebrae: 33 - 36. Body elongate and laterally compressed, particularly posteriorly . Snout elongate, dorsoventrally compressed and wide, in lateral view concave posterior to premaxillary pedicels . Eye large . Mouth large and oblique, caudal margins of maxilla and premaxilla terminate at level of vertical located at about 1/3 distance through orbit from anterior margin . First dorsal-fin origin located well posterior to vertical through pelvic-fin insertion, at about 3/4 of distance between pelvic- and anal-fin origins; with 4-6 feeble unbranched rays . Second dorsal-fin origin located well posterior to vertical through anal-fin origin, at about 1/3 distance along anal-fin base; with 11-14 rays . Flanks covered with large, regularly imbricate cycloid scales; head asquamate from tip of snout through interorbital region to posterior margin of orbit, except for single, enlarged, dorsal interorbital scale that extends anteriorly to approximately mid-orbit; cheek scaled; opercle scaled except along caudal margin, and subopercle scaled except along caudal or caudoventral margin; interopercle scaled; lacrimal and posterior margin of preopercle asquamate; 19-20 predorsal scales, and 37-38 scales in longitudinal series . Base body coloration dark olive to dark grayish-brown dorsal of lateral midline, white or pearlescent ventral to lateral midline; prominent, wide black midlateral stripe present and continuous, some iridescent golden scales present within midlateral stripe centrally on body and dorsal to midlateral stripe posteriorly on flanks; chest and belly white or pearlescent .
