Vedclass · Answer

(B) Some marine dinoflagellates,such as $Gonyaulax$,undergo rapid multiplication and cause 'red tides' in the sea. These organisms secrete potent toxins known as saxitoxins. When these toxins are ingested by marine organisms like shellfish,they accumulate in their tissues. When humans consume these contaminated shellfish,the saxitoxin enters the human food chain and causes paralytic shellfish poisoning,which results in paralysis.
