WebAlexandrium catenella is a harmful algal bloom (HAB)-forming dinoflagellate that causes significant damage to the cultivation and harvest of shellfish due to its synthesis of paralytic shellfish toxins. Alexandrium is an opportunistic dinoflagellate and thus it can bloom in nutrient-rich and nutrient-poor areas. Alexandrium fundyense crece principalmente en ambientes marinos de baja salinidad durante los meses de primavera y verano. 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.
