Microalgae. Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. [1] They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a ...
Dinoflagellate. The dinoflagellates ( Greek δῖνος dinos "whirling" and Latin flagellum "whip, scourge") are a monophyletic group of single-celled eukaryotes constituting the phylum Dinoflagellata [5] and are usually considered protists. Dinoflagellates are mostly marine plankton, but they also are common in freshwater habitats.
Marine biogenic calcification refers to the production of calcium carbonate by organisms in the global ocean. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues. This process is a fundamental aspect of the life ...

Nekton. Nekton or necton (from the Greek: νηκτόν, translit. nekton, lit. "to swim") refers to aquatic organisms that can actively and persistently propel themselves (i.e. swim) through a water column. The term was proposed by German biologist Ernst Haeckel to differentiate between the active swimmers in a body of water, and the planktons ...
Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind ). [1] [2] The individual organisms constituting plankton are called plankters. [3] In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish, and ...
Most zooplankton are microscopic but some (such as jellyfish) are macroscopic, meaning they can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, foraminiferans, radiolarians, some dinoflagellates and marine microanimals.
