Pelvic fin origin far forward, midway between pectoral fins and anal fin or nearer the pectoral fins; pectoral fins much longer than pelvic fins after about 7 mm; anal fin origin under 1st-3rd dorsal fin ray (usually second dorsal or third); barbels or beak never form; prominent pigment blotch distally on upper pectoral fins after about 8 mm; prominent bar across tail at level of last half of dorsal and anal fins after about 12 mm; more upper gill rakers (7-8) than E. monocirrhus (4-6). Notochord flexion occurs before hatching.
Pigmentation:
Larvae: on upper half of head except little or none on snout before about 8.4 mm; covering trunk and gut except none ventrally on gut until 8-10.5 mm; on dorsal and ventral margins and lateral midline of tail to middle of caudal peduncle, extending to last 12 myomeres by 7 mm; dorso- and ventrolaterally on anterior 60% of tail, extending to end by 8 mm; bar at level of last half of dorsal and anal fin after 12 mm; blotch forms on distal 30-40% of upper pectoral fin (rays 1-2 to 5-7) after 8 mm; caudal fin pigment principally along lower rays, forms after 16 mm; dorsal, anal and pelvic fins usually unpigmented.
Juvenile: heavy pigment on upper part of head and trunk; bar at midtail may extend onto dorsal and anal fins; distal blotch on upper part of pectoral fins; proximal blotch on middle of pelvic fins. |
