The fish is able to use the parasite just like a normal tongue. It appears that the parasite does not cause any other damage to the host fish.[2] Once C. exigua replaces the tongue, some feed on the host's blood and many others feed on fish mucus. This is the only known case of a parasite functionally replacing a host organ
