The real science

The tongue-eating louse is a tiny ocean parasite that slips into a fish through its gills and clamps onto the tongue. It drains the tongue's blood supply until the tongue withers away, then grips the stump and works as the fish's new tongue. It is the only known parasite that replaces an organ of its host.
