Light micrograph of marine zooplankton dinoflagellatea, from the flagellate group of protozoa. Found in both freshwater & saltwater, dinoflagellates can feed either like plants (photosynthesis) or like animals (taking in preformed food such as algae, diatoms) or like both. The photosynthetic substance they possess is brown not green. Occasionally a large massing of dinoflagellates in the ocean gives a red- coloured bloom to the water. Magnification: x200 at 35mm.
