Parvilucifera

Parvilucifera is a genus of marine alveolates that behave as endoparasites of dinoflagellates. It was described in 1999 by biologists Fredrik Norén and Øjvind Moestrup, who identified the genus among collections of Dinophysis dinoflagellates off the coast of Sweden. Initially mistaken for products of sexual reproduction, the round bodies found within these collections were eventually recognized as sporangia, spherical structures that generate zoospores of a parasitic protist. This organism was later identified as P. infectans, the type species. The examination of this organism and its close genetic relationship to Perkinsus led to the creation of the Perkinsozoa phylum within the Alveolata group.

The complex life cycle of Parvilucifera consists of biflagellated zoospores that infect a variety of dinoflagellate species, become intracellular feeders or trophonts, and finally develop into sporangia that generate more zoospores. Parvilucifera species could help control dinoflagellate harmful algal blooms.
