Reproductive Biology
Fully grown H. sanguineus females can likely produce >50,000 eggs at a time (Fukui, 1988[1]; McDermott 1998b[2]). The eggs of H. sanguineus are of intermediate size (0.015 mm3), relative to other co-occurring grapsid crabs in Japan (Fukui, 1988[3]). The eggs hatch into larvae, which proceed to molt through five zoeal stages to become megalopae (Hwang et al., 1993[4]). Megalopae can be found in the water column or on the benthos (Hwang et al., 1993[5]; Lohrer, 2000[6]). After settlement and metamorphosis, the first crab stage is usually between 1.6 and 2.0 mm carapace width (Epifanio et al., 1998[7]; Lohrer, 2000[8]). The time from hatching to first instar undoubtedly varies with latitude, but takes 25+ days under optimal conditions (warm water of high salinity) (Hwang et al., 1993[9]; Epifanio et ...
