A flagellated, single celled organism, less than 1mm in size, classified as plants or animals since some contain chlorophyll. Found in two main groups: armored and naked.
mostly single-celled, often photosynthetic algae that live in fresh and marine waters
Single-celled to colonial protistans characterized by two flagella, one girdling the cell and the other trailing the cell.
Unicellular algae that are often covered in thick, armoured plates
Single-celled algae; some produce toxins and all are food for shellfish.
minute phytoplankton which move by means of flagellae (long whip like appendages). Some dinoflagellates are responsible for red tides.
planktonic, single-celled marine invertebrates that move through the water by flagella (hair-like appendages); some species responsible for producing the toxin ciguatoxin.
Small, single-celled organisms that live in the sea. Dinoflagellates are an important component of phytoplankton and a source of bioluminescence at the surface of the ocean. See What is a Dinoflagellate and Dinoflagellate Bioluminescence. View photographs of bioluminescent phenomena at Bio Bay.
Unicellular biflagellate algae with thick cellulose plates.
A group of single-celled microscopic organisms with flagella that belong to the kingdom Protista. If they posses chlorophyll, they are considered plants and some are entirely photosynthetic while some ingest food. If they don't posses chlorophyll, they are more animal-like. The symbiotic algae zooxanthellae are dinoflagellates. "Red Tide" is caused by a dinoflagellate bloom that releases toxins into the water. Amyloodinium (Marine "Velvet") is also caused by dinoflagellates.
A group of marine phytoplankton, some of which produce biotoxins.
Algae of the Phylum Pyrrhophyta. A diverse group of algae which are single cells with two flagella of different length. One flagellum is located in a transverse furrow which encircles the entire cell, the other is in a longitudinal furrow perpendicular to the first furrow along one half of the cell. Of all the algae, these are the fastest moving. [Gk. deinos, terrible + L. flagellum, whip.
Single celled, microscopic, flagella posessing organisms...some photosynthetic, others animal like. Both toxic "Red Tide" and marine "Velvet" disease are caused by these organisims. Zooxanthellae is an example of a beneficial plant like dinoflagellate ( Symbiodinium spp.)
a type of protist that includes photosynthetic forms in which two flagella project through armor-like plates. Abundant in oceans, these sometime reproduce rapidly, causing "red tides."
common type of phytoplankton, most abundant in fall; responsible for â€œred tidesâ€ as well as bioluminescence.
Parasitic organisms such as Oodinium, which are characterised by hair-like flagella. These are used for locomotion and contain the green pigment chlorophyll.
Any of numerous minute, chiefly marine protozoans.
a type of green plant cells that swims with flagella.
