Most plankton is microscopic, especially that found in freshwater. Marine plankton have exclusively whole groups of organisms that are very visible to the naked eye, e.g. Ctenophores (sea gooseberries). All plankton is divided into the plant-type plankton, the phytoplankton, and the animal plankton, zooplankton.The latter can be further sub-divided into the temporary and permanent zooplankton.
