The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
The Anisakidae are a family of intestinal nematodes (roundworms). The larvae of these worms can cause anisakiasis when ingested by humans, in raw or insufficiently cooked fish. Anisakidae worms can infect many species of fish, birds, mammals and even reptiles. [1] They have some traits that are common with other parasites.
The Texas cichlid (Herichthys cyanoguttatus), also known as the Rio Grande cichlid, is a freshwater fish of the cichlid family, and the only cichlid species that is native to the United States. It is found in the lower Rio Grande drainage in Texas near Brownsville and northeastern Mexico .
The Camallanida are an order of nematodes. They are parasites of terrestrial and aquatic vertebrates. They also use copepods as obligatory secondary hosts. [citation needed] They are sometimes included in the Spirurida as a suborder Camallanina. [citation needed]
This wound on the fish then heals, leaving almost no scarring. Species of Philometra require two hosts to complete their life cycle. After the larval worms are released from the host fish, they are ingested by copepods which act as an intermediate host. Once inside the copepod, the larvae molt several times. Fish may then eat the infested copepod.
Myleusnema bicornis is an intestinal parasite of Myleus ternetzi, or "Ternetz's Silver Dollar", a freshwater Characoid fish commonly found in the French Guiana river. [1] M. bicornis has several unusual morphological characteristics, namely the two postcloacal "horns" in the posterior of males, and a separate elongated cephalic region (head) that may be extended and retracted.

Enoplea (enopleans) is a class, which with the classes Secernentea [1] and Chromadorea make up the phylum Nematoda in current taxonomy. [2] [3] [4] The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea.
Anisakis simplex, known as the herring worm, is a species of nematode in the genus Anisakis. Like other nematodes, it infects and settles in the organs of marine animals, such as salmon, mackerels and squids. [2] [3] It is commonly found in cold marine waters, such as the Pacific Ocean and Atlantic Ocean. [4] [5]
