subdivision = "See text"The gill lice are a genus ("Ergasilus") of
copepod crustaceans occurring in both the ocean andfresh water . The females are parasitic upon the gills of fishes. This is similar to members of the crustacean subclassBranchiura (fish lice). Being copepods, gill lice have a single median eye on their head. The second antennae are modified into prehensile pincers. Male gill lice are free-living [cite web |url=http://encarta.msn.com/encyclopedia_762508602/Fish_Lice.html |title=Fish lice |work=Encarta |publisher=MSN ] .Species include :
