Noctilucales

Fig 1: Noctiluca scintillans Schematic drawing of the ventral side of the cell

Pronoctiluca (= Pelagorhynchus marinus Pavillard, 1917). Cells are 35-45 microns, nose flexible but cannot be retracted, that it has a thick flexible theca, inclusions of various sizes, and a large anterior nucleus, encysts but does so without loosing flagella. Sournia argues this is Pronoctiluca, a common dinoflagellate.

Round inflated vegetative cells that can be more than 1 mm in diameter. Cells are unarmoured and bear one flagellum and a tentacle. No distinct anterior and posterior parts are discernible. This species can form extensive blooms which can lead to fish kills.
