Structure. Gonyaulax, genus of dinoflagellate algae (family Gonyaulacaceae) that inhabit marine, fresh, or brackish water. Phylum Dinozoa. Studies of phytoplankton are essential to understand food chain dynamics in aquatic ecosystems (Sieburth and Davis, 1982).In oligotrophic waters, the base of the food chain is composed of very small cells in the size range 0.2–2 μm [‘picoplankton' (Sieburth et al., 1978)] and the microbial loop dominates the pelagic food web (Fenchel, 1988). Gonyaulax belongs to red dinoflagellates and commonly causes red tides.. Infraphylum Dinoflagellata Buetschli, 1885. 2008. [2], Paz et al. Introduction.
