Taxonomic Description: A chain-forming species species, A. catenella typically occurs in characteristic short chains of 2, 4 or 8 cells (Figs. 1,2). Dinoflagellates are important primary producers for marine ecosystems and are also responsible for certain essential components in human foods. However, they are also notorious for their ability to form harmful algal blooms, and cause shellfish poisoning.
