Cymothoa exigua is a small crustacean found off the coast of California. You don't have to worry about it unless you are a spotted rose snapper. C. exigua invades the mouth of these fish and grabs onto the base of the tongue, pinching off the blood supply and drinking it. As the tongue atrophies, the fish begins to use the little isopod as a replacement tongue. [emphasis mine]
