Two xanthid crabs, toxic species Zosimus aeneus and nontoxic species Daira perlata wereexamined for resistibility against paralytic shellfish poison (PSP) and tetrodotoxin (TTX). In the former crab, the minimum lethal dose (MLD) of scallop PSP consisting mainly of gonyautoxinswas estimated to be 10, 000 MU/20g body weight, and MLD of TTX 1, 000 MU/20g, both MLD values being comparable to the corresponding values in another toxic xanthid crab Atergatis floridus reported previously. On the other hand, D. perlata was not resistible against scallop PSP and TTX, both MLDs being around 1 MU/20g. However, some specimens of this crabwere found to survive when crab PSP consisting mainly of saxitoxins was administered at levels of 100-500 MU/20g.
