Plankton are organisms drifting in oceans, seas, and bodies of fresh water. The word zooplankton is derived from the Greek zoon (Î¶á¿´Î¿Î½), meaning animal, and planktos (ÏÎ»Î±Î³ÎºÏÏÏ), meaning wanderer or drifter.Individual zooplankton are usually microscopic, but some (such as jellyfish) are larger and visible with the naked eye.t includes holoplanktonic organisms whose complete life cycle lies within the plankton, as well as meroplanktonic organisms that spend part of their lives in the plankton before graduating to either the nekton or a sessile, benthic existence.
