Yolk-sac       Ref:  
Yolk segmented Oil globules one oil globule
Rows on tail ventral + lateral row
Other melanophores on tail no other melanophores
Melanophores on head + trunk melanophores on trunk
Yolk-sac - early preflexion: dorsal pigment series migrates to form paired ventrolateral series between gut and trunk extending posteriad to notochord tip; short series above notochord tip.

Slender, elongate, attaining a maximum length of about 30 mm; elongate straight gut (about 85-90% BL), not trailing; small head arched ventrad; small elliptical eyes; pigment series above and below gut; dorsal fin and anal fin form near caudal fin at flexion stage; paired fins form at transformation. Pigmentation: Yolk-sac - early preflexion: dorsal pigment series migrates to form paired ventrolateral series between gut and trunk extending posteriad to notochord tip; short series above notochord tip. Late preflexion-flexion: series lateral to isthmus; gular patch; on lower jaw, postorbital region; lateral hindbrain, and terminal gut section. Postflexion: series above gut recessed in ventral trunk; sparse on caudal fin, dorsal fin and anal fin; on postorbital region. Transformation: melanophores on dorsal myomere absent. Sequence of fin development: caudal and dorsal and anal, pelvics and pectorals.
