Body width between pectoral fin-bases 25-40%; 12 tail rings. Sequence of fin development: pectoral (1.4-3.8 mm); dorsal (2.8-3.8 mm); anal (2.8-3.8 mm); pelvic (2.8-> 6.7 mm); caudal 3.4-4.2 mm). Body elongate to moderate, initially round in cross-section, much wider than deep by postflexion stage. Head moderate to large, initially round, dorsoventrally flattened by flexion stage. Mouth small, terminal in preflexion larvae, subterminal in postflexion larvae. Gill opening small and located at dorsal margin of pectoral fin base in preflexion larvae and flexion larvae, extending along entire pectoral fin base in postflexion larvae. Gut moderate to long, coiled. Pectoral fin large and fan-shaped in postflexion larvae. One pelvic fin ray during flexion stage, elongate and segmented; second ray from 6.7 mm, shorter than first and unsegmented. Dermal bony plates present by 2 mm, with a single, median dorsal ridge and pointed ridges above and below eye; sharp bony ridges over head, trunk and tail during flexion stage, fully ossified by early postflexion stage. |
