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 ...
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.

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 ...

Unlike mammals, the red blood cells of fish have DNA, and can become infected with viruses. The fish develop pale gills, and may swim close to the water surface, gulping for air. However, the disease can also develop without the fish showing any external signs of illness, the fish maintain a normal appetite, and then they suddenly die.
The parasite is 0.5 mm (0.02 in) long, [2] and cannot be seen with the naked eye, but it can be seen with a magnifying glass. [6] On its posterior end is a haptor, a specialized organ for attaching to the host fish, which has sixteen hooks around its edge. [2] The parasite is viviparous, that is, it produces live offspring. [7]
The second antennae and oral appendages are modified to assist in holding the parasite on the fish. The second pair of antennae is also used by males to grasp the female during copulation. [ 18 ] The adult females are always significantly larger than males and develop a very large genital complex, which in many species makes up the majority of ...
