  • Kawachi, M., Inouye, I., Honda, D., O'Kelly, C. J., Bailey, J. C., Bidigare, R. R. & Andersen, R. A.(2002) The Pinguiophyceae classis nova, a new class of photosynthetic stramenopiles whose members produce large amounts of omega-3 fatty acids. Phycological Research 50: 31-47.

The Pinguiophyceae was described in 2002. They inhabit exclusively in marine. The pinguiophycean algae produce high amount of unsaturated fatty acids, especially eicosapetaenoic acid (EPA).

All pinguiophycean algae are unicellular but the shape is varied such as flagellate, naked non-motile, walled cocoid and loricate. Major carotenoid is fucoxanthin and the chloroplast is yellowish. Phaeomoans possesses heterpdynamic two flagella which are typical for stramenopiles. However, the gliding zoospores of Polypodochrysis and Glossomastix lack no. 2 flagellum. The transitional region includes no transitional helix but proximal helix.
