These protists are referred to as mixotrophs since they can both consume organisms/organic materials and perform photosynthesis in order to get food: It's a "mix" of both autotrophic and heterotrophic ability. The results revealed bloom dynamics of the two toxic Alexandrium species in the Bohai Sea for the first time, and further confirmed A. catenella as the causative agent of poisoning episodes. Alexandrium is an opportunistic dinoflagellate and thus it can bloom in nutrient-rich and nutrient-poor areas. Additionally, scallops exposed to A. catenella showed histopathological features, especially after 6 days of exposure, including increased melanization of the tissues and myopathy, with high levels of degeneration of the muscle fibers.
