Once inside, the female latches onto the base of the fish’s tongue, while the male attaches behind her or on the gills. Through her front claws, she sucks the fish’s blood, which causes the tongue to die and drop off. She will then re-attach, this time to the tongue stub, effectively becoming its replacement. With an eww factor of 10, the fish can and will use the parasite as if it were its natural tongue.
