ABSTRACT
Saxitoxin is the parent compound of a group of neurotoxic alkaloids collectively termed paralytic shellfish toxins (PSTs). The primary producers of PSTs are prokaryotic freshwater cyanobacteria (“blue-green algae”) and eukaryotic marine dinoflagellates; however, they are readily transferred to and accumulate in other aquatic organisms, including mollusks, gastropods, and puffer fish.
