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.
Amphoroidea is a genus of isopod of the family Sphaeromatidae, containing the following species:
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.
Idotea is a genus of isopod crustaceans, mostly from cold temperate waters. The taxonomy of the genus is still in doubt, and many of the currently recognised species may be taxonomic synonyms, and others may be moved to different genera.
Cirolanidae is a family of aquatic isopods.
Paracerceis is a genus of isopod crustaceans in the family Sphaeromatidae. It contains 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 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.
Dynoides is a genus of isopod crustaceans in the family Sphaeromatidae, containing the following species:
Cirolana is a genus of isopod crustaceans.
Exosphaeroma pentcheffi is a species of marine isopod of the family Sphaeromatidae.
Exosphaeroma amplicauda is a species of marine isopod of the family Sphaeromatidae.
Aega is a genus of isopods in the family Aegidae, containing the following species:
Exosphaeroma laeviusculum is a species of isopod in the family Sphaeromatidae, native to the west coast of southern Africa.
Dynoides amblysinus is a species of isopod in the family Sphaeromatidae.
Dynoides viridis is a species of isopod in the family Sphaeromatidae. It was first found on Heron Island, Great Barrier Reef.
Dynoides castroi is a species of isopod in the family Sphaeromatidae.
Dynoides serratisinus is a species of isopod in the family Sphaeromatidae. It is found in the Indian Ocean.
Dynoides dentisinus is a species of isopod in the family Sphaeromatidae.
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.
