Gonyaulax polygramma Stein, 1883 Species Overview: Gonyaulax polygramma is an armoured, planktonic marine dinoflagellate species. Several planktonic species are toxic and are sometimes abundant enough to colour water and cause the phenomenon called red tide, which may kill fish and other animals.Humans may be poisoned by eating mussels or other shellfish that have ingested large quantities of Gonyaulax catenella.

Gonyaulax spinifera, previously considered a non-YTX producer, was isolated from the seawater samples and production of YTX by the cells grown in culture was … Order Gonyaulacales Taylor, 1980.
