Context: Caligus is a genus of sea lice in the family Caligidae.  The species are parasites of marine fishes and could be vectors of viruses.  s of 2017 , the World Register of Marine Species includes the following species: The salmon louse, Lepeophtheirus salmonis, is a species of copepod in the genus "Lepeophtheirus".  It is a sea louse, a parasite living mostly on salmon, particularly on Pacific and Atlantic salmon and sea trout, but is also sometimes found on the three-spined stickleback.  It lives off the mucus, skin and blood of the fish.  They are natural marine parasites of fish such as adult salmon.  Once detached they can be blown by wind across the surface of the sea, like plankton.  When they encounter a suitable marine fish host they may adhere themselves to the skin, fins, the gills of the fish, and feeding off the mucus or skin.  Sea lice only affect fish and are not harmful towards humans.
