Lepidodinium is a genus of dinoflagellates belonging to the family Gymnodiniaceae.[1] Lepidodinium is a genus of green dinoflagellates in the family Gymnodiniales. It contains two different species, Lepidodinium chlorophorum and Lepidodinium viride.[1] They are characterised by their green colour caused by a plastid derived from Pedinophyceae, a green algae group. This plastid has retained chlorophyll a and b, which is significant because it differs from the chlorophyll a and c usually observed in dinoflagellate peridinin plastids.[2] They are the only known dinoflagellate genus to possess plastids derived from green algae.[2] Lepidodinium chlorophorum is known to cause sea blooms, partially off the coast of France, which has dramatic ecological and economic consequences.[3][4][5] Lepidodinium produces some of the highest volumes of Transparent Exopolymer Particles of any phytoplankton, which can contribute to bivalve death and the creation of anoxic conditions in blooms, as well as playing an important role in carbon cycling in the ocean.[5][6]
