12. Tongue Eating Louse
A monster, yes, but more of a parasitic creature that is just as hideous. The male tongue eating louse attaches itself and enters the fish through the gills, while the female attaches itself onto the fish’s tongue. It then cuts off the blood vessels of the fish’s tongue, cutting the tongue off completely, positions itself on what was once the tongue and becomes the new tongue. We had to mention the word “tongue” so many times.
