THE ALIEN TONGUE
Cymothoa exigua or tongue-eating louse is a parasitic crustacean that penetrates the body of a fish, sticks to its tongue and literally devours it. Then this parasite clings by its claws to what is left from the fish’s tongue and starts to functions in its stead so well that the fish does not even notice the substitute. Of course, if the fish could speak maybe it would say: “Hmm, why am I lisping so? And, bloody hell, where is this accent from?” But, alas, fish are mute.
