Most do some photosynthesis, but not all; some of the dinoflagellates that photosynthesize also consume prey. Dinoflagellates are protists that fall under the phylum dinoflagellata. The group is an important component of phytoplankton in all but the colder seas and is an important link in the food chain. Dinoflagellates do need certain trace elements from the water. Predation of Dinoflagellates by Corals: Amphidinium and Gymnodinium. (Pics attached) Tank Info: 30 gallon softie reef 5 months old RO water Salinity 1.025 Ammonia 0 Nitrite 0 Nitrate 1 Calcium 440 Alkalinity 8 Phosphate 0 (according to API) I plan on getting a more accurate kit for phosphates Dinoflagellate, (division Dinoflagellata), any of numerous one-celled aquatic organisms bearing two dissimilar flagella and having characteristics of both plants and animals. Facts about Dinoflagellates 6: the description of the first modern Dinoflagellates Henry Baker was the first scientist who described the first modern Dinoflagellates in 1753. I have manually siphoned the dinoflagellates out of the sand, and will do some partial water changes to reduce nutrients...Are there any certain types of fish or inverts who will eat this...Any certain Gobies? It is ironic that an animal (coral) dependent upon one dinoflagellate genus (Symbiodinium) would ingest and digest other types of dinoflagellates. Therefore, within the sea life majority of the micro-organisms like bioluminescent dinoflagellates are independent of their need for food on a single source or on other organisms alone. Dinoflagellates or some other algae type? Sorokin (1973) found that corals could eat the … What do bioluminescent dinoflagellates eat? Eliminating harmful and ugly dinoflagellates remains one of the most common—and challenging—tasks for the marine aquarist. Dinoflagellate flashes cause a startle response in their predators, disrupting their feeding behavior and resulting in a decrease in grazing rate by reducing the number of dinoflagellates consumed. If you were to change your bands of salt, you could be removing these trace elements causing the dinoflagellates to die off. The life cycle of the organisms is also complex, involving forms that are immobile and capable of movement and forms that are capable of sexual or asexual reproduction (bacteria, for example, reproduce asexually, by the self-replication of their genetic material and other constituents). Not all dinoflagellates are autotrophic, however, and some do not photosynthesize at all.They can also exist by several variably heterotrophic strategies including species that are phagotrophic (ingesting whole cells), saprophytic (feeding on decaying matter), parasitic (feeding directly on other organisms), and mutualistic (living in mutually beneficial symbioses). Starting to use RO/DI water with 0 TDS (Total Dissolved Solids) will also help if you are currently using tape water. What can I add to my tank that will eat some dinoflagellates that are on my sandbed. Most are marine, though some live in freshwater habitats. This condition may cause poisoning on human if they eat the contaminated shellfish. Still other dinoflagellates can do both. It is no doubt that bioluminescent dinoflagellates are of marine origin and their life cycle is bounded within the sea.
