The parasite then replaces the fish's tongue by attaching its own body to the muscles of the tongue stub. [7] The parasite apparently does not cause much other damage to the host fish, [2] but Lanzing and O'Connor (1975) reported that infested fish with two or more of the parasites are usually underweight. [8] Once C. exigua replaces the tongue ...
Tongue worms grow by moulting, which suggests they belong to Ecdysozoa, while other work has identified the arthropod-like nature of their larvae. [12] In general, the two current alternative interpretations are: pentastomids are highly modified and parasitic crustaceans, probably related to fish lice, or they are an ancient group of stem ...
The Cymothoidae are a family of isopods in the suborder Cymothoida found in both marine and freshwater environments. Cymoithoids are ectoparasites, usually of fish, and they include the bizarre "tongue-biter" (Cymothoa exigua), which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body.

Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).

After reaching the duodenal mucosa, the larvae migrate to the abdominal cavity, where they spend about a week until they are encapsulated in the host tissue. Over a three-month period, the parasite molts five additional times, increasing in size and developing segmentation. The sex of the parasite becomes identifiable after the fifth molt.
