Dinoflagellate blooms are generally unpredictable, short, with low species diversity, and with little species succession. [73] The low species diversity can be due to multiple factors. One way a lack of diversity may occur in a bloom is through a reduction in predation and a decreased competition. The first may be achieved by having predators ...

Dinoflagellate, (division Dinoflagellata), any of numerous one-celled aquatic organisms bearing two dissimilar flagella and having characteristics of both plants and animals. Most are marine, though some live in freshwater habitats.

Feb 24, 2021 · The dinoflagellate is a single-celled aquatic organism with two flagella. It is known to cause bioluminescence in the ocean. Dinoflagellates are found in fresh and saltwater and, in large numbers, can produce dangerous levels of neurotoxic chemicals.

Dinoflagellates are the most common sources of bioluminescence at the surface of the ocean. This section describes the life history and ecology of dinoflagellates, and explains how and why they produce bioluminescence. What is a dinoflagellate?

Dinoflagellates are single-celled aquatic organisms with two flagella, exhibit bioluminescence in oceans and can produce neurotoxic chemicals in large quantities. The first modern dinoflagellate was described by Baker in 1753, the first species was formally named by Muller in 1773.

Dinoflagellates are unicellular organisms with a size range similar to diatoms, but with a larger proportion of very small forms that escape through the mesh of fine plankton nets (nanoplankton).

Dinoflagellates are an important group of phytoplankton that produce oxygen in marine and freshwater. Some species form symbiotic relationships with larger animals, including corals (zooxanthellae), jellyfish, sea anemones, nudibranchs and others.

Mar 22, 2024 · 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.

Dinoflagellates are common organisms in all types of aquatic ecosystems. Roughly half of the species in the group are photosynthetic (Gaines and Elbrächter 1987), the other half is exclusively heterotrophic and feeds via osmotrophy and phagotrophy.

The majority of dinoflagellate species are marine, and together with coccolithophores and diatoms they make up the most important primary producers in the oceans. Dinoflagellates are also common in freshwater lakes, rivers and bogs and can occur in blooms of sufficient concentration to discolour the water, producing what are known as "red tides".
