Anuropus Branchiatus
''Anuropus'' is a genus of isopods in the suborder Cymothoida. , it is the only genus in the family Anuropidae. Taxonomic history The genus ''Anuropus'' was first circumscribed by the English zoologist Frank Evers Beddard in 1886. His new genus coincided with his description of the type species, '' A. branchiatus''. Beddard placed ''Anuropus'' in the family Cymothoidae 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 att ..., but in 1893, Thomas Roscoe Rede Stebbing wrote it "may have greater claims to be the type of a distinct family, Anuropidæ". In 1903, Hans Jacob Hansen thought ''Anuropus'' might possibly belong to the subfamily Cirolaninae or perhaps a new subfamily Anuropinae. Species , World Register of Marine Species recognizes the following ten species in this genus: * ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List ...

Isopod
Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax. Isopods have various feeding methods: some eat dead or decaying plant and animal matter, others are grazers, or filter feeders, a few are predators, and some are internal or external parasites, mostly of fish. Aquatic species mostly live on the seabed or bottom of freshwater bodies of water, but some taxa can swim for a short distance. Terrestrial forms move around by crawling and tend to be found in cool, moist places. Some species are able to roll themselves into a ball as a defense mechanism or to conserve moisture. There are over 10,000 identified species of isopod worldwide, with around 4,50 ...
