Step-by-step explanation:

Saxitoxin, the seafood toxin, is most commonly found in marine organisms affected by red tide, which is a harmful algal bloom caused by dense populations of dinoflagellates. This toxin is primarily produced by species such as Gonyaulax, Alexandrium, and Pfiesteria piscicida. Red tide can contaminate shellfish, which can then cause paralytic shellfish poisoning in humans when consumed.
