Scallop escape response to predator was modified by A. catenella. Corey Johnson Obituary, The presence of PSTs in several of these organisms reveals that toxins produced by A. catenella are more prevalent in California food webs than previously thought and also indicates potential routes of toxin transfer to higher trophic levels. Many protists also form colonies. They also form large aggregations in the coastal waters of China, but the abundance varies greatly in different locations and between years (Dong et al., 2010). photosynthesize, so it does not have chloroplasts.
