Anabaena is a genus of filamentous N2-fixing cyanobacteria and are known for producing a suite of cyanotoxins which range from the neurotoxic anatoxins and saxitoxins to the hepatotoxic microcystins. Although this genus can be found throughout the world, microcystin-producing Anabaena blooms have not yet been described in Australia where saxitoxin is more predominantly described in this genus.
