They possess a trailing flagellum, which can often be longer than the cell itself.Their patterns of movement tend to be very consistent, constantly moving utilizing their flagellum to maneuver themselves within the water column. Interestingly, natural grazing by ciliate microzooplankton controls the Amoebophyra, as they ingest the infective dinospores, and thus in turn indirectly effect the occurrence of red tides.
