Pfiesteria piscicida is a species Classification of Se hela listan på tolweb.org Another characteristic of the dinoflagellates is the wall composition and structure; early classification of the dinoflagellates was based on the presence (termed armoured) or absence (termed unarmoured) of a rigid outer cell covering (or theca). Evidence has since been found to suggest there is an intergradation between these types.

Neither plant nor animal, dinoflagellates are unicellular protists; most exhibit the following characteristics: They are planktonic. Ninety percent of all dinoflagellates are marine plankton. Others are benthic, symbiotic, or They are small. Although many of them are microscopic and range from 15

Some of these organisms are photosynthetic, meaning they can synthesize their own food from carbon dioxide and water. Others are heterotrophic, meaning they cannot synthesize their own food. Likewise, what are most dinoflagellates? Dinoflagellates characteristics are as follows – Most dinoflagellates are marine planktons, but some are also found in freshwater. Their distribution depends on the pH level, temperature and depth of the aquatic ecosystem. Their flagella are responsible for locomotion and facilitate a spinning top-like motion.
