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.
Curassanthura is a genus of isopod crustaceans in the family Leptanthuridae. It contains the following species:
Anthuroidea is a superfamily of isopod crustaceans, formerly treated as a suborder, Anthuridea. The group is characterised by "an elongate cylindrical body form, without dorsal coxal plates, and with a uropodal exopod attached to the peduncle proximally and dorsally". There are more than 500 described species in 57 genera, arranged across six families:
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:
The Idoteidae are a family of isopod crustaceans. It includes these genera:
Eurydice is a genus of isopod crustaceans named after the mythical Eurydice, wife of the musician Orpheus. It includes the following species:
The Cirolanidae are a family of isopod crustaceans, including these genera:
The Leptanthuridae are a family of isopod crustaceans, containing the following genera:
Gnathia is a genus of isopod crustaceans, containing the following species:
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 shrimps. 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.
The Chaetiliidae are a family of isopod crustaceans in the suborder Valvifera, comprising these genera:
Agnaridae is a family of woodlice. They were formerly considered part of the Trachelipodidae, but were moved from that family to Porcellionidae in 1989, and then placed as a separate family in 2003.
The Arcturidae are a family of marine isopod crustaceans in the suborder Valvifera. Members of the family resemble woodlice and are found globally in cooler areas in shallow seas.
Dynoides is a genus of isopod crustaceans in the family Sphaeromatidae, containing the following species:
Uromunna sheltoni is a species of isopod first described by Brian Kensley in 1977. U. sheltoni is included in the genus Uromunna and family Munnidae. No subspecies are listed. The species was first collected by Peter Shelton of the University of Cape Town, for whom it is named.
Uromunna is a genus of isopod crustaceans, containing the following species:
Cirolana is a genus of isopod crustaceans.
Exosphaeroma is a genus of marine isopod of the family Sphaeromatidae. This genus is found in shallow ocean waters worldwide. It is notable for being one of the few genera of sphaeromatid to be found in the southern reaches of the Southern Ocean. The greatest diversity of Exosphaeroma occurs in the Southern Hemisphere.
Aega is a genus of isopods in the family Aegidae, containing the following species:
Scutuloidea kutu is a species of marine isopods in the family Sphaeromatidae, first described by Stephenson and Riley in 1996. No subspecies are listed in the Catalog of Life. The name "kutu" was chosen as a metaphor, as the species lives on seaweed.
