Pics show parasite that enters fish's mouth, eats its tongue and then replaces it

Pictures show a parasite that enters a fish through its gills, eats its tongue and then replaces it. Cymothoa exigua, or the tongue-eating louse, belongs to the Cymothoidae (ectoparasite) family. After replacing the fish's tongue, it then feeds on the fish's mucus. The parasite was discovered among an import of fish in Suffolk, UK, in June.
