Feeding and burrowing ecology of two East African mangrove crabs

Feeding and burrowing ecology of two East African mangrove crabs 227 111 111 2 2 F. Micheli F. Gherardi M.

Both species occupy upper intertidal levels, above mean high-water neap, and completely overlap in their zonation. Each burrow lasts ca. 3 wk, with no significant difference between the species. Both are more active around dusk and dawn and also follow a similar trend in their foraging activity, but differ in that burrowing is mainly diurnal in C. carnifex and nocturnal in S. meinerti.
