Abstract: | The larval ontogeny of Hypseleotris galii is described and illustrated. 'Premature' yolk sac larvae hatch with unpigmented eyes and no mouth. 'Late' yolk sac larvae hatch with pigmented eyes and a functional mouth. Hatching glands are distributed on the head and ventral surface of the body. The yolk is absorbed and the larvae begin feeding 6 days after hatching. Larval development is completed 74 days after hatching. Hypseleotris galii larvae have six pairs of naked neuromasts: two pairs on the head and four pairs on the body. The significance of these results to developmental strategies in Hypseleotris species is discussed. |
