Large, early forming pectoral fins; moderately large pelvic fins; strongly inflated dermal sac, with tubercles bearing up to 20 small spinules each beginning at 2.5-3 mm; pigment dorsally and dorsolaterally on trunk and distally on pectoral fins beginning at about 2 mm; band usually present around tail. Pigmentation: Preflexion-postflexion: dorsal and dorsolateral, initially at nape, spreading caudad to level of anus by early postflexion stage; usually band around tail in vicinity of postanal myomeres 8-13; dorsally, dorsolaterally, and anteriorly on gut; under mid- and hindbrain; under opercle; usually on pectoral fin base, increases in postflexion stage; usually some distally on pectoral fin blade or rays after 2 mm, usually forming short bands near middle and distal parts of upper pectoral fin in postflexion stage. Juvenile: completely pigmented except belly and pelvic fins. Sequence of fin development: pectorals, caudal, pelvics and ilicium (first dorsal fin spine modified to form a lure), dorsal, anal. |
