Produced by marine cyanobacteria such as Lyngbya, aplysiatoxins are commonly known for their dermatotoxic activity causing inflamation of the skin. They are also potent tumour promoters. Aplysiatoxins and debromoaplysiatoxin have been found associated with filamentous cyanobacterial species including Schizothrix calcicola and Oscillatoria nigroviridis.
