Amoebas, for example, are animal-like protists that engulf their prey and break them down inside their cell in order to get their nutrition. Alexandrium catenella is an armored dinoflagellate, approximately 24-24m long and 22-44m wide. The interrelation study between the occurrence of the blooms and specific external conditions at the study sites demonstrated that different factors are required for the bloom of each Alexandrium species. cyst concentrations in marine sediments. overwinters as a cyst in the MeSH This leads to three general classes of protist: Each of these classifications can help shed light on how they get food and nutrition.

The blooms of A. catenella and A. pacificum were found in April and July, respectively, and PST content in three bivalves exhibited notable increase following the bloom of A. catenella. 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. Since 1998, blooms of Alexandrium catenella associated with paralytic shellfish poisoning have been repeatedly reported for Thau Lagoon (French Mediterranean coast).
