Pinguiophycidae Kawachi et al. 2002 stat.

nov. Cavalier-Smith 2006 Pinguiochrysidaceae is a family of marine Heterokontophyta.

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.
