The gill lice are a genus ("Ergasilus") of copepod crustaceans occurring in both the ocean and fresh water. The females are parasitic upon the gills of fishes. This is similar to members of the crustacean subclass Branchiura (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] .
