Pinguiophyceae is a class of marine Heterokontophyta.[1] It includes five species of unicellular organisms with high concentration of polyunsaturated fatty acids in the cytoplasm.[1] The other common features are the lack of cell wall and the tendency for flagella loss even on the stage of zoospore, which is unusual for heterokonts.[1] One species (Polypodochrysis teissieri) inhabits benthic substates (sometimes found the mucilage of other algae) and is able to produce lorica with one or more tubular necks.[2] The other species live in the plankton.[1]
