In order to elucidate the infestation mechanism of toxic crabs with paralytic shellfish poison (PSP), three xanthid crabs (Zosimus aeneus, Atergatis floridus and Platypodia granulosa) collected from Ishigaki Island and Miura Peninsula, were surveyed for stomach contents. Stomach contents of the three toxic crabs from Ishigaki Island consisted of red algae, animal tissues, corals, sand, etc., irrespective of their PSP toxicity levels. The same stomach contents composition was encountered in a nontoxic crab Daira perlata examined for comparison. Stomach contents of A. floridus specimens collected from Miura Peninsula showed a somewhat different composition, in which Hypnea sp., bivalves, gastropods, animal tissues and sand were dominant. No definite conclusion was drawn from these data, as to the association of the eating habit of these toxic crabs with their PSP toxification.
