Eu·gle·ni·da (u-gleґnĭ-də) an order of plantlike, flagellate protozoa of the phylum Euglenozoa, order Euglenoidea. If there are chromatophores, they are green; there are usually one or two, rarely more, flagella protruding from an anterior invagination; and a small stigma is located anteriorly in colored forms. Species are usually found in fresh water, although some inhabit salt or brackish water, and a few are parasitic. See also euglenoid movement, under movement.
