Members of Parviluciferaceae behave as
endoparasitoids of
dinoflagellates, an important group of
marine phytoplankton. Their
life cycle consists of
biflagellated
zoospores with two unequally sized
flagella, that swim toward dinoflagellate hosts, infect them and grow into
sporangia that develop more zoospores. All genera share similar sporangium morphology and life cycle. Their main differences regard the morphology of zoospores.
Dinovorax and
Snorkelia zoospores infect the host cell through a
germ tube, which is absent in
Parvilucifera. == Systematics ==
