Kokkale, mondsichelförmige Peridinee aus dem Plankton tropischer und subtropischer Meere. Endogene Bildung von ein oder zwei eingeißeligen Dinosporen (gymnodiniumartiger Bau), Ausschwärmen, Umwandlung von Dinosporen in vegetative Zellen. Mit Zeitraffung.

The coccoid crescent-shaped dinoflagellate Pyrocystis lunula belongs to the oceanic plankton of tropical and subtropical seas. the alga reproduces asexually by forming endogenously one or two dinospores (=zoospores). These are Gymnodinium-like, bearing only a single flagellum. Shedding their cell envelopes newly released dinospores are instantly able to develop into crescent-shaped cells again.
