Based on data obtained for rRNA gene markers, it has been suggested that the strains involved could be closely related to the Japanese temperate Asian ribotype of the temperate Asian clade. This means that they create their own food without having to eat or engulf other organisms/organic materials in the environment. 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). We conducted a 4-year survey in King Harbor, CA, to investigate the seasonal dynamics of Alexandrium catenella and the presence of a particulate saxitoxin (STX), the parent compound of the PSTs.
