what are some examples of marine protists?

The Protista is a large complex grouping of mostly unicellular eukaryotic organisms. Paul V. Dunlap, in Encyclopedia of Biodiversity (Second Edition), 2001. Multicellular protists may include brown algae and certain red algae. •live primarily in marine habitats •because blue light penetrates water better than other wavelengths, red algae are able to live at considerable depths in the ocean •most photosynthetic, some parasitic. Some dinoflagellates have a net-like structure called a protoplasmic net—used to capture and eat prey that are typically larger in size than bacteria. These are single-celled (e.g., Monosiga), aquatic (both fresh water and marine) protists that have a single flagellum surrounded by a collar ("choano" = collar) of microvilli. Protista. Cells of protists have a nucleus which contains their genetic material. But there are exceptions. Protists have very complex cells, more complex than any other group of organisms. Some marine organisms harbor light-emitting bacteria, which forms a symbiotic relationship working to create an effect called bioluminescence, and the light produced could be used to hunt prey, defend against predators, and also find mates 1. An example of a unique organelle only found in some species of protists is a contractile vacuole. For example, some of the viruses might have infected the protists or simply become stuck to the surfaces of the cells. Most protists are single-celled and microscopic. Some (e.g., Proterospongia) form simple colonies during part of their life. Nearly all protists exist in some type of aquatic environment, including freshwater and marine environments, damp soil, and even snow. The majority of their organelles are the same as those found in animals, plants and fungi but some are unique. Several protist species are parasites that infect animals or plants. Ciliates are capable of catching bacteria, other protists and phytoplankton. ... for Biochemistry & Molecular Biology, Biotechnology, Botany, Ecology & Environmental Studies, Forensic Biology, Marine Biology, Microbiology, Physiology, Zoology and Wildlife Biology, and more. Some groups have large species indeed; for example, among the brown algal protists some forms may reach a length of 60 metres (197 feet) or more. They are morphologically diverse and can be found in most terrestrial, aquatic, and marine habitats as free-living forms and as parasites of other protists, of fungi, and of plants and animals. Some examples are: Microsporidia. For example, it is here where some protists receive energy from the sun to produce nutrients through a process called photosynthesis. Some dinoflagellate species are also responsible for harmful fish kills and the infamous red tides. A contractile vacuole is used by a cell to pump water. Some marine slime molds have unique life cycles that involve switching between unicellular, colonial, and multicellular forms. Organelles inside the cells carry out defined functions within the cell. Examples of protists include algae, amoebas, euglena, plasmodium, and slime molds. Some single-celled marine protists are macroscopic. A few protist species live on dead organisms or their wastes, and contribute to their decay. Protists can be grouped according to similarities in a number of different categories including nutrition acquisition, mobility, and reproduction. •some red algae because encrusted with calcium carbonate, contribute to reef building and help stabilize the entire reef structure. Protists Examples The descriptions of protists are presented in the following paragraphs. Some examples of exclusively photosynthetic protists include some phytoplankton and unicellular algae. But Brown and Stepanauskas said that some types of viruses were found only in certain groups of protists, hinting that the interactions weren’t just happenstance. Other marine protist are neither single-celled nor microscopic, such as seaweed. Other marine protist are neither single-celled nor microscopic, such as seaweed single-celled microscopic.
