Dinoflagellates range in size from about 5 to 2,000 micrometres (0.0002 to 0.08 inch). Most are microscopic, but some form visible colonies. Nutrition among dinoflagellates is autotrophic, heterotrophic, or mixed; some species are parasitic or commensal.

LM (Light Microscope) SEM (Scanning Electron Microscope). Typical and selected marker species are illustrated from each main period of the geological column in which dinoflagellates occur. The images are divided into Cenozoic and Mesozoic forms, click on a link below or scroll down to each section.

Clear cellulose shell (theca) often visible as outline of the cell. The most common bloom culprit and accounts for the majority of tank losses due to dinos, can make long strands by combination of microfibers and mucus. Two types of cysts: short term - hours to days, or long term - months until warmth and nutrients are favorable.

Dinoflagellates are unicellular and possess two dissimilar flagella arising from the ventral cell side (dinokont flagellation). 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.

Here dino-flagellate means only that they have whirling flagella! Note that dinoflagellates are older than dinosaurs and they probably occurred, in evolution, before the first eukaryotes. Some theories propose that they are an association of an algae and a bacteria.

Dinoflagellates, the most common sources of bioluminescence at the sea surface, are readily grown in the laboratory. They produce bright bioluminescence upon agitation. The following instructions describe how to obtain dinoflagellate cultures and …

2024年3月22日 · Dinoflagellates are single-celled eukaryotic microorganisms, primarily found in marine environments, characterized by two whip-like flagella that facilitate movement. Many species are photosynthetic, and they play vital roles in aquatic ecosystems, ranging from primary producers to causing phenomena like bioluminescence and red tides.

2015年1月1日 · Dinoflagellates are a group of unicellular protists that can be identified using the light microscope, and are (usually) recognized by their golden-brown plastids, assimilative cell with indented waist, distinctive swimming pattern, …

Dinoflagellates, the most common sources of bioluminescence at the sea surface, are readily maintained and grown almost anywhere. They produce bright bioluminescence when agitated. The following instructions describe how to give a most impressive demonstration!

Dinoflagellates (Peridinium) are single-celled organisms that propel though watery environments by waving two thread-like structures referred to as flagella. These mostly marine creatures are participants in plankton communities that drift along sea currents and serve as an important source of food for many aquatic animals.
