Abstract

Scylla serrata in a South African estuary occurred more frequently in that part which had the highest number of prey organisms. Food location was by contact chemoreception, using the dactyls of the walking legs. Major prey groups were burrowing bivalves, attached bivalves and small crabs. s. serrata showed a preference for small crabs as prey. Because of their larger mass and higher energy content compared with other prey organisms, these crabs represented the major energy source of S. serrata in this area.
