Dinoflagellates are found all over the ocean, but do not contribute to ocean sediments. Why??? Many Dinoflaggelates have an eyespot that is sensitive to light.

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.

Dinoflagellates: Characteristics, Classification, Life Cycle By admin Biology , Science 0 Comments The dinoflagellates are agencies of the United Protista whose main characteristic is that they have a pair of flagella that help you move in the middle. Dinoflagellater (Dinophyta, Dinoflagellata) som även kallas pansarflagellater [1] är en grupp encelliga alveolater.

They are mainly marine, though few are fresh water forms. They may appear red, yellow, green, brown or blue depending upon the main pigment present in cell. General characters of dinoflagellates are as follows : Dinoflagellates (Division or Phylum Pyrrhophyta) are a group of primarily unicellular organisms united by a suite of unique characteristics, including flagellar insertion, pigmentation, organelles, and features of the nucleus, that distinguishes them from other groups. Most dinoflagellates contain Characteristics of Dinoflagellates. Have you ever seen photos of seawater lit up with a shiny, blue luminescence?

In some cases, the relationship between the dinoflagellates and their host organism is symbiotic. In these symbiotic relationships, the host incorporates the dinoflagellates into itself without damage to either organism, and they both benefit from the nutrients they receive from each other.

These species reproduce in such great numbers that the water may appear golden or red, producing a "red tide". When this happens Dinoflagellates are surrounded by a complex covering called the amphiesma, which consists of outer and inner continuous membranes, and between which lie a series of flattened vesicles. In armored forms, these vesicles contain the thecal plates, cellulose plates that are the "armor". 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.

Dinoflagellates are tactical. For something so small, they are surprisingly clever. When the water around them is disturbed, certain types of dinoflagellates will emit a bright, blue light – an action which experts believe is either designed to confuse any prey nearby, or to attract other, larger organisms that are further up the food chain to the area, thus potentially eating what is

They have a ribbon-like transverse flagellum with multiple waves that beats to the cell's left, and a more conventional one, the longitudinal flagellum, that beats posteriorly. Dinoflagellates are encrusted with plates made of a cellulose-like material and silica. Most dinoflagellates contain the pigments chlorophyll-a, chlorophyll-c and carotenoids, which allow them to Dinoflagellate, (division Dinoflagellata), any of numerous one-celled aquatic organisms bearing two dissimilar flagella and having characteristics of both plants and animals.
