Cymothoa Exigua – Weird Parasite

Cymothoa exigua (Tongue eating louse) attaches itself to a fish’s tongue. It starts to suck blood through the claws on its front legs. As it grows, less blood can reach the tongue and it atrophies. That’s when the parasite replaces the tongue attaching his body to the muscles. The fish uses it like a normal tongue.
