Rhadinorhynchidae [1] is a family of parasitic worms from the order Echinorhynchida.
Rhadinorhynchidae has 4 subfamilies (Golvanacanthinae, Gorgorhynchinae, Rhadinorhynchinae, and Serrasentoidinae) and the following species: [2] [lower-alpha 1]

G. occultus has been found parasitising the Cobbler wobbegong (Sutorectus tentaculatus) in Bunbury, Western Australia. The proboscis of this worm has 18 to 20 rows of 8 or 9 hooks followed by a well-developed neck. The body contains irregular circles of small spines in a single anterior portion. The male reproductive system limited to the posterior quarter of the trunk. There are three cement glands. [3]

R. decapteri is a parasite of the marine fish Round scad (Decapterus punctatus) and is found coastal waters of Brazil. It has 10 longitudinal rows of 22–26 hooks. The species name decapteri was derived from the genus (Decapterus) of the type host. [8]
R. mariserpentis parasitizes the Oarfish, Regalecus russelii and has been collected near Wakamatsu-ku, Kitakyūshū, Japan.
R. trachuri is one of the most widespread acanthocephalans infesting fish from the Eastern Pacific, Western Pacific, and Indian Oceans. On the South pacific coast of Vietnam, it was found infesting the Frigate tuna (Auxis thazard), and the Torpedo scad (Megalaspis cordyla). [13]

Rhadinorhynchidae species parasitize fish hosts.
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.
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.
Echinorhynchida is an order of parasitic worms in the phylum Acanthocephala. It contains the following families:
Arhythmacanthidae is a family of parasitic worms from the order Echinorhynchida.
Cavisomidae are 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.
Illiosentidae is a family of parasitic worms from the order Echinorhynchida.
Plagiorhynchidae is a family of parasitic Acanthocephalan worms.
Transvenidae is a family of parasitic spiny-headed worms in the order Echinorhynchida. This family contains three species divided into two genera.
Gorgorhynchus is a genus of worms belonging to the family Rhadinorhynchidae.
Rhadinorhynchus is a genus of worms belonging to the family Rhadinorhynchidae.
Cathayacanthus is a genus of worms belonging to the family Rhadinorhynchidae.
Pallisentis is a genus in Acanthocephala.
Neoechinorhynchus is a genus of parasitic worms belonging to the family Neoechinorhynchidae.
Pseudoacanthocephalus is a genus of parasitic worms belonging to the family Echinorhynchidae.
Rhadinorhynchus mariserpentis is a species of parasitic thorny-headed worm within the family Rhadinorhynchidae. The species is a endoparasite of Regalecus russeli, with the type locality coming from an intestine of an individual collected in the Sea of Japan off the coasts of northern Kyushu.
