Bigyromonad


Bigyromonadea is a recently described non-photosynthetic lineage of stramenopiles that at present contains two subdivisions.

Description

Bigyromonads are characterized by biciliate cells that feed on bacteria through phagotrophy. They are marine organisms.

Taxonomy

was thought to only include the parasitoid genus Pirsonia. In 2024, more genera were added to Pirsoniales, showing that this group also contains eukaryotrophic species.
