| Abstract: | Eggs of the giant mudskipper, Periophthalmodon schlosseri were collected from a burrow in Penang, Malaysia, in November 1998, and hatched larvae were reared in the laboratory. The
eggs were demersal with adhesive filaments and elliptical in shape (0.83–1.43 mm in long-axis diameter). Newly hatched larvae
(2.1–2.6 mm in notochord length) possessed a yolk sac. The number of myomeres was 10 + 17 = 27. The mouth and anus were already
opened. The larvae started feeding one day after hatching and completely absorbed the yolk by the third day at a water temperature
of 24.5–28.0°C.
