They are found dispersed throughout the photic zone of the oceans and account for the major share of primary productivity in the marine environment. The most important phytoplankton that are presently recognized are those 2 -20 µm Based on protein content, the marine plankton can be classified as phytoplankton (plant plankton) and zooplankton (animal plankton). Zooplankton may be classified according to their habitat, depth-wise distribution, size and life cycle (Omori and Ikeda 1984).On the basis of habitat, the zooplankton is classified as marine plankton or haliplankton and freshwater plankton or limnoplankton. sphere. The ocean water contains living (plankton) and non-living (detrital) particles. The importance of plankton for the global ecosystem cannot be overestimated. Microscopic algae, phytoplankton, are sometimes called the grasses of the sea. Just like land plants, they consume carbon dioxide and produce oxygen through photosynthesis. Phytoplank- Marine phytoplankton which constitutes diatoms, dinoflagellates, blue-green algae, silicoflagellates, cocolithophors etc. contributes about 95% of primary production in the oceans. On this depends the secondary production (zooplankton) and tertiary production (fish, shellfish, mammals, etc.). The traditional method for identifying metazoan plank- ton involves examination of formalin-preserved specimens. Monographs and descriptions in the primary literature are avail- able for comparing a sample to named species. This is especially effective for Crustacea, which often dominate the net-collected plankton. present identification keys since these already exist (refer to Section 4). Rather, the attempt was to clearly outline the basic essential elements that must be understood by novices to the field who require guidance for the identification of their samples. the air by terrestrial dust storms and ocean plankton swept into the air from sea spray. Although many species of plankton are microscopic in size, plankton includes organisms in a wide range of formats, including large organisms such as jellyfish. [4] Plankton are defined by their ecological niche and level of motility, rather than from any Part 1: Identification of Microscopic Plankton Organism Size Morphology Microscope Identification Virus 0.01 to 0.3 µm Viruses have a capsid, or protein coat that holds their DNA.
