Since 1998, recurrent toxic (Paralytic Shellfish Poisoning) blooms of Alexandrium catenella occur in Thau lagoon (French Mediterranean coast) during spring and/or autumn. Alexandrium is an opportunistic dinoflagellate and thus it can bloom in nutrient-rich and nutrient-poor areas. These toxins can affect various physiological functions including reproduction. When it comes to small and microscopic organisms, it can be a bit more difficult to understand, especially when you have a diverse group of organisms like you do in the Kingdom Protista.

These Their round cells are identified by the shape and position of their pores and are often found in chains although solitary cells can also be Their round cells are identified by the shape and position of their pores and are often found in chains although solitary cells can also be observed. Of those species that are now classified as Alexandrium, the first to be described was Goniodoma ostenfeldii, by Paulsen These colonies aren't technically multicellular organisms, though. Blooms of the highly toxic dinoflagellate Alexandrium catenella (previously referred to as tamarense group 1) were first detected off eastern Tasmania in 2012 and have since been responsible for incidences of human paralytic shellfish poisoning and extended closures (up to 25 weeks) of mussel, oyster, scallop, abalone and rock lobster industries (up to 150 mg/kg PST in mussels).
