Plankton are organisms that drift in water but are unable to actively propel themselves against currents. Marine plankton include drifting organisms that inhabit the saltwater of oceans and the bracki
Marine microplankton and mesoplankton Part of the contents of one dip of a hand net. The image contains diverse planktonic organisms, ranging from photosynthetic cyanobacteria and diatoms to many different types of zooplankton, including both holoplankton (permanent residents of the plankton like copepods) and meroplankton (temporary residents of the plankton like fish eggs and crab larvae). 100 μm is one tenth of a mm
