Aegiochus is a genus of isopods in the family Aegidae, first described in 1885 by Carl Bovallius. [1] [2] The type species is Aega ventrosa . [3]
Species accepted by WoRMS [1] are:
Sphaeromatidae is a family of isopods, often encountered on rocky shores and in shelf waters in temperate zones. The family includes almost 100 genera and 619 known marine species. Within these genera, there are groups that share distinctive morphologies; further research may reclassify these genus-groups as separate families.
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", which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body. Ceratothoa oestroides is one of the most devastating ectoparasites in Mediterranean aquaculture. Around 40 genera and more than 380 species of cymothoid are recognised. Species of the Cymothoidae are generally found in warmer waters and rarely in the cool and cold climates.
Iais is a genus of isopod crustaceans. Iais species are found in association with larger isopods of the family Sphaeromatidae, usually on the ventral surface of the larger animal, between the pereiopods and on the pleopods. They are native to Australasia and South America, although Iais californica and its host Sphaeroma quoyanum have invaded California, and I. californica was first described from Sausalito, California. Nine species are recognised:
Paracerceis is a genus of isopod crustacean in the family Sphaeromatidae. It contains the following species:
Cymothoida is the name of a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing.
Cymothoa is a genus of parasitic isopod crustaceans, containing the species listed below. Not all Cymothoa species are considered parasitic. Some climb onto fish in an act known as phoresy.
The Bopyridae are a family of isopod crustaceans in the suborder Cymothoida. There are 1223 individual species contained in this family. Members of the family are ectoparasites of crabs and shrimp. They live in the gill cavities or under the carapace where they cause a noticeable swelling. Fossil crustaceans have occasionally been observed to have a similar characteristic bulge.
Aega is a genus of isopods in the family Aegidae, containing the following species:
Nerocila is a genus of parasitic isopod crustaceans, with 11 species, which have been found parasitizing Indian marine fishes.
Elthusa is a genus of isopods in the family Cymothoidae, with 40 described species.
Ceratothoais a genus of isopod ectoparasites of teleost fish, first described by James Dwight Dana in 1852. Infection by Ceratothoa can cause anaemia, lesions, growth retardation, emaciation, and mortality in their fish hosts.
Anuropus is a genus of isopods in the suborder Cymothoida. As of 2021, it is the only genus in the family Anuropidae.
Antarcturidae is a family of marine isopods belonging to the suborder Valvifera.
Tridentella is a genus of crustaceans belonging to the monotypic family Tridentellidae.
Leptanthura is a genus of isopod crustaceans in the family Leptanthuridae. It was first described in 1897 by Georg Ossian Sars and the type species is Paranthura tenuis. It is found in coastal waters throughout the world, and contains the following species:
Rocinela is a genus of isopods in the family Aegidae, and was first described in 1818 by William Elford Leach. The type species is Rocinela danmoniensis Leach, 1818.
Aegiochus bertrandi is a species of isopod in the family Aegidae, and was first described in 2009 by Niel L. Bruce. The species epithet, bertrandi, honours the French zoologist Bertrand Richer de Forges.
Aegiochus piihuka is a species of isopod in the family Aegidae, and was first described in 2009 by Niel L. Bruce. The species epithet, piihuka, is a Mäori word meaning hook, and refers to the hooked anterior legs.
Natatolana is a genus of crustaceans in the family Cirolanidae, first described by Niel L. Bruce in 1981. The type species is Cirolana hirtipes Milne Edwards, 1840.
