Acanthogyrus
Acanthogyrus is a genus of parasitic worms in the family Quadrigyridae. They live in fish, mainly in Africa. The genus was described by Thapar in 1927. In 1959, Golvan divided Acanthogyrus into two subgenera based on the number of hooks on the worm’s proboscis: Acanthogyrus (Acanthogyrus) with 24 hooks (three circles of eight) and Acanthogyrus (Acanthosentis) with 18 hooks (three circles of six). Overall, the proboscis has 18 to 24 hooks. There are many species in this group. Examples include Acanthogyrus (Acanthogyrus) found in the intestines of rohu (Labeo rohita) in Lucknow and catla (Catla catla) in Kolkata, India. Acanthogyrus (Acanthosentis) includes A. barmeshoori, found in the Farsi toothcarp (Aphanius farsicus) in Iran. In short, Acanthogyrus are fish parasites, with many species mainly in Africa, and two subgenera distinguished by the hook count on their proboscis.
