A potent neurotoxin found in shellfish, such as the mussel or the clam, produced by the dinoflagellate Gonyaulax catenella, which is ingested by the shellfish; the cause of cases of poisoning from eating California sea mussel (Mytilus californianus), the scallop, and the Alaskan butterclam (Saxidomus giganteus).

saxi·tox·in .sak-sə-'täk-sən n a potent nonprotein neurotoxin C10H17N7O4·2HCl that originates in dinoflagellates of the genus Gonyaulax found in red tides and that sometimes occurs in and renders toxic normally edible mollusks which feed on them

saxi·tox·in (sakґsĭ-tok″sin) a powerful, heat-stable, low molecular weight neurotoxin synthesized and secreted by certain dinoflagellates, such as species of Gonyaulax; it accumulates in the tissues of bivalve mollusks feeding on the dinoflagellates, and persons eating such mollusks can get either neurotoxic or paralytic shellfish poisoning (see under poisoning). Called also shellfish poison.
