Total vertebrae 75-77; gut loop formed by about 6.8 mm and positioned centrally in the visceral cavity; usually 2 pigment patches dorsally near end of tail. Pigmentation: Preflexion: on angle of lower jaw; ventral body midline below pectoral fin; at bottom of gut loop; above gas bladder; 4-6 patches ventrally along tail; 1 (small) occasionally between main ventral patches; anterior of the two dorsal tail melanophores occasionally absent. Flexion: along ventral midline of gut; on branchiostegals; on base of anal fin rays. Postflexion: on lower jaw and on caudal fin. Sequence of fin development: pelvics, pectorals, caudal, dorsal and anal. |
