Extremely long eye stalks, average 53% HL in preflexion and flexion stages, decreasing in postflexion stage; heavy pigment series on gut and myomeres. Pigmentation: Preflexion: lateral gut series becomes subdivided (series of 4-5 on terminal section, 8-12 on hindgut, up to about 12 on foregut); patch on opercle; series of 3 lateral to liver; series of 3 embedded at isthmus; on lower jaw; subocular, from jaw to opercle; series on hypaxial myomeres from pectoral fin to caudal fin; below tip of notochord. Flexion-postflexion: hind- and foregut series increase to 12-15; series on hypaxial myomeres along entire body in late postflexion stage; on snout; on anterior surface of pectoral fin base. Transformation: several per myomere in epaxial and hypaxial series. Sequence of fin development: caudal, anal, pectorals, dorsal and pelvics. |
