A female Sesarma haematocheir incubates 30 000-50 000 eggs on her abdomen. After one month of embryonic development, zoeae larvae are released into estuarine waters within 3-5 sec by means of vigorous fanning motions of the abdomen. Hatching (breakage of the outer egg membrane) occurs on land just before larval release. Stimuli from the female are apparently important in establishing highly synchronized hatching. -from Author
