The green turban shell Turbo marmorata, the turban shell Turbo argyrostoma, and the top shells Tectus pyramis and Tectus nilotica maxima, all collected on coral reefs of Ishigaki Island, Okinawa, were found to contain paralytic shellfish poisons in the viscera. The regional and seasonal variation in toxicity strongly suggested an exogenous origin of the toxins. The feeding habits and habitat of the gastropods suggested that the primary source of the toxins was a benthic organism.<br> The analysis of the toxin composition of the first three species revealed a trace amount of gonyautoxin III in T. argyrostoma and a small amount of gonyautoxin II and neosaxitoxin in all three species. Saxitoxin was the most abundant component in all species, . The next most abundant component was found to be a new toxin, which was named turban shell toxin (TST). It was difficult to distinguish TST form saxitoxin by Bio-Rex 70 column chromatography and electrophoresis, but TST was separable from saxitoxin by thin layer chromatography.
