title: Toxicity and paralytic shellfish toxin profiles of the xanthid crabs, Lophozozymus pictor and Zosimus aeneus, collected from some Australian coral reefs.
abstract: Purification of toxic aqueous extracts from the xanthid crabs Zosimus aeneus and Lophozozymus pictor, collected from Australian waters, yielded paralytic shelfish toxins, including saxitoxin (STX), neosaxitoxin (neoSTX) and gonyautoxins 1, 2 and 4 (GTX1,2,4). No more than two paralytic shellfish toxins were found in any of the purified extracts from any specimen. Four specimens of Z. aeneus and one specimen of L. pictor each contained more toxic material than the suggested human oral lethal dose. The moult of a specimen of L. pictor was toxic, which may indicate a route in crabs for toxin removal.
