Cavisomidae are a family of parasitic worms from the order Echinorhynchida.
Cavisomidae contains the following genera: [1] [lower-alpha 1]
CaballerorhynchusSalgado-Maldonado, 1977 contains one species:
CavisomaVan Cleave, 1931 contains one species: Cavisoma magnum(Southwell, 1927) [2] C. magnum (Southwell, 1927) Van Cleave, 1931 was originally described as Oligoterorhynchus magnus by Southwell [3] from the stomach and pyloric ceca of the sea bass, Serranus sp. (Serranidae) and from another fish, the spotted surgeonfish Ctenochaetus strigosus (Acanthuridae) off Negapatam, (Sri Lanka). Other hosts include milkfish Chanos chanos (Chanidae), [4] [2] Siganus lineatus (Siganidae), [5] and Grey mullet, Mugil cephalus (Mugilidae). [2] Localities include Sri Lanka, the Red Sea, the Philippines, New Caledonia, and Iraq. [2]

Cavisomidae species parasitize fish.
Eoacanthocephala is a class of parasitic worms, within the phylum Acanthocephala. They feed on any aquatic cold-blooded creature such as turtles and fish. Their proboscis spines are arranged radially, with no protonephridia, and with persistent ligament sacs in female. The only reliable way to identify the group is that they only have one cement gland. This is a primitive characteristic and hence the name. The class contains 2 orders:
Quadrigyridae is the only family within Gyracanthocephala, an order of parasitic worms of class Eoacanthocephala. This family contains two subfamilies, ten genera and about 92 species.
Acanthocephalus is a genus of parasitic worms. One of the species in this genus is Acanthocephalus anguillae, a fish parasite. Acanthocephalans are also found in humans and primates, causing a common zoonotic infection called "human acanthocephaliasis". While pathogens can be transferred among animals and humans, the main source of human acanthocephaliasis is the diet of infected raw fish and insects. Because they are lacking circulatory, respiratory, and digestive systems, Acanthocephalus are exceptionally well-adapted to a symbiotrophic existence.
The thorny-headed worm family Polymorphidae contains endoparasites which as adults feed mainly in fish and aquatic birds. When this taxon was erected by Meyer in 1931, a subfamily Polymorphinae was established in it. As the Polymorphidae as presently understood would then be monotypic, with no basal genera outside the Polymorphinae, the proposed subfamily is redundant for the time being and therefore most modern treatments simply omit it. Polymorphus minutus is an economically significant parasite in goose and duck farming.
Moniliformidae is a family of parasitic spiny-headed worms. It is the only family in the Moniliformida order and contains three genera: Australiformis containing a single species, Moniliformis containing eighteen species and Promoniliformis containing a single species. Genetic analysis have determined that the clade is monophyletic despite being distributed globally. These worms primarily parasitize mammals, including humans in the case of Moniliformis moniliformis, and occasionally birds by attaching themselves into the intestinal wall using their hook-covered proboscis. The intermediate hosts are mostly cockroaches. The distinguishing features of this order among archiacanthocephalans is the presence of a cylindrical proboscis with long rows of hooks with posteriorly directed roots and proboscis retractor muscles that pierce both the posterior and ventral end or just posterior end of the receptacle. Infestation with Monoliformida species can cause moniliformiasis, an intestinal condition characterized as causing lesions, intestinal distension, perforated ulcers, enteritis, gastritis, crypt hypertrophy, goblet cell hyperplasia, and blockages.
Centrorhynchidae is a family of parasitic worms. Three species of these thorny-headed worms in the genus Centrorhynchus were found to parasitize birds of prey and owls Slovakia. These hosts include Buteo buteo, Buteo rufinus, Falco tinnunculus, Asio otus, Strix aluco, Strix uralensis and Tyto alba.
Arhythmacanthidae is a family of parasitic worms from the order Echinorhynchida.
Diplosentidae is a family of parasitic worms from the order Echinorhynchida.
Echinorhynchidae is a family of acanthocephalan parasitic worms from the order Echinorhynchida. The adult worms live in the intestines of fishes, amphibians and reptiles. The family contains the following genera, organised by subfamily.
Pomphorhynchidae is a family of parasitic worms from the order Echinorhynchida.
Fessisentis is a genus of parasitic spiny-headed worms. It is the only genus in the family Fessisentidae. This genus contains six species that are distributed across the Eastern continental United States as far west as Oklahoma and Wisconsin. These worms parasitize salamanders and fish.
Leptorhynchoididae is a family of parasitic worms from the order Echinorhynchida.
Rhadinorhynchidae is a family of parasitic worms from the order Echinorhynchida.
Plagiorhynchidae is a family of parasitic Acanthocephalan worms.
Euzetacanthus is a genus in Acanthocephala.
Cathayacanthus is a genus in Acanthocephala.
Cavisoma is a monotypic genus of acanthocephalans containing a single species, Cavisoma magnum, that infests animals.
Caballerorhynchus is a monotypic genus of acanthocephalans containing a single species, Caballerorhynchus lamothei, that infests animals.
Filisoma is a genus in Acanthocephala.
Neoechinorhynchus is a genus of parasitic worms belonging to the family Neoechinorhynchidae.
