Chattonella subsalsa
belongs to the class Raphidophyceae. This class comprises about six genera (half freshwater, half marine). Selected marine genera have been extensively studied because of their toxicity (Horner et al. 1997, Marshall et al. 2003). The relationships of the Pinguiophyceae and Raphidophyceae are largely unresolved.

Chattonella subsalsa
represents a genus that has caused immense losses to the finfish aquaculture industry worldwide [e.g.157 million dollars worth of farmed yellowtail in Japan (Okaichi 1989)]. Brevetoxin-like compounds are produced by this alga (Khan et al. 1995)
