Sea LiceSea lice is the common term used for one group of parasitic caligid copepods which occur naturally on fish world-wide. Copepods are crustaceans found in both marine and freshwater environments. Most are planktonic, while others are found living in the sediments. Some species are specialized to live as parasites, on or in host organisms at some stage in the lifecycle, although one or more stages are free-living as plankton in the water, usually during the early stages of development.
