| Abstract |
Larval and early juvenile development of laboratory-reared frillfin gobies, B. Soporator is described and figured. One-day old preserved specimens average 2.0 mm SL, had 11-12 preanal myomeres, and 25-26 total myomereces. Caudal fin rays appeared at 3.1 mm SL (10 days), followed by soft dorsal and anal fin rays at 3.4 mm SL (11 days). Dominant larval pigmentation consisted of dense rows of stellate melanophores along the dorsal and anal midlines and later along the lateral midline. The change to juvenile growth was characterized by migration of the eyes to the adult position, rounding of the caudal fin margin, beginning of scale formation, and separation of the upper pectoral fin rays. Sequence of ossification is described and figured. |
