dinoflagellate di·no·flag·el·late (dī'nō-flāj'ə-lĭt, -lāt', -flə-jěl'ĭt)
Any of numerous chiefly marine flagellates of the order Dinoflagellata, some species of which produce a potent neurotoxin that may cause severe food poisoning following ingestion of parasitized shellfish.
Any of numerous one-celled organisms found mostly in the ocean, usually having two flagella of unequal length and often an armorlike covering of cellulose. Dinoflagellates are one of the main components of plankton. Since dinoflagellates have characteristics of both plants and animals, their classification is controversial. See more at red tide.
