Lyngbyatoxin-a is a cyanotoxin produced by certain cyanobacteria species, notably Moorea producens (formerly classified as Lyngbya majuscula). It is used as a defensive secretion to protect this cyanobacteria from predation by fish, being a potent irritant and vesicant, as well as a carcinogen. Low concentrations more commonly encountered cause milder symptoms, known as seaweed dermatitis.^{[1][2][3][4][5][6]}
