Bacterioplankton are bacteria and archaea, which play an important role in remineralising organic material down the water column (note that many phytoplankton are also bacterioplankton). Plankton are found throughout the oceans, seas and lakes of Earth.
Bioluminescent Noctiluca scintillans (a dinoflagellate). Plankton is composed of the phytoplankton (the plants of the sea) and zooplankton (zoh-plankton) which are typically the tiny animals found near the surface in aquatic environments.Like phytoplankton, zooplankton are usually weak swimmers and usually just drift along with the currents.eroplankton and holoplankton are a component of almost every taxonomic group. However, the most common plankton are protists, nanoplanktonic flagellates, cnidarians, ctenophores, rotifers, chaetognatha, veliger larvae, copepods, cladocera, euphausids, krill and tunicates.
