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.
Curassanthura is a genus of isopod crustaceans in the family Leptanthuridae. It contains the following species:
Serolis is a genus of isopod crustacean, 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. Nine species are recognised:
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.
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.
Sphaeroma terebrans is a mangrove-boring isopod that was first documented in the United States as early as 1897. It is 8–10 millimetres (0.31–0.39 in) long, and is thought to have been introduced by wooden-hulled ships. The isopod is found throughout the Gulf of Mexico mainly in mangrove swamps of Louisiana and Florida. S. terebrans will also bore into boats, wooden pilings and other wooden structures.
Serolidae is a family of isopod crustaceans, containing the following genera :
Platyarthridae is a family of woodlice, containing the following genera:
The Aegidae are a family of isopod crustaceans. The adults are temporary parasites of fish, feeding on their hosts' blood before dropping off to digest the meal. They differ from members of the family Cirolanidae in having only three pairs of hook-like pereiopods, whereas in Cirolanidae all seven pairs of pereiopods are hooked. The family was first described by Adam White in 1850 and contains the following genera:
Glyptonotus antarcticus is a benthic marine isopod crustacean in the suborder Valvifera. This relatively large isopod is found in the Southern Ocean around Antarctica. It was first described by James Eights in 1852 and the type locality is the South Shetland Islands.
Ligia baudiniana is a woodlouse in the family Ligiidae. It has a coarsely granular surface and large eyes that are very close together.
Ligia dilatata is a woodlouse in the family Ligiidae.
Porcellio dilatatus is a species of woodlouse in the genus Porcellio belonging to the family Porcellionidae. This species is widespread in Europe, and has also been introduced to North America from Western Europe. They are 15 millimetres (0.59 in) long, are brown coloured and striped. They can be found feeding on alder leaves, but mostly feeds on organic food substrates, such as lettuce in the wild. It also feeds on inorganic metal salts.
Trachelipus ratzeburgii is a species of woodlouse in the genus Trachelipus belonging to the family Trachelipodidae that can be found in Austria, the Baltic states, Belgium, the Netherlands, Croatia, the Czech Republic, France, Germany, Hungary, Italy, Poland, Romania, Slovakia, Switzerland and Scandinavia. The species has three subspecies:
Porcellionides cilicius is a woodlouse that can be found on Cyprus and in Turkey. The species have one subspecies Porcellionides cilicius antiochensis that can be found only on Cyprus.
Uromunna is a genus of isopod crustaceans, containing the following species:
Glyptidotea is a monotypic genus of isopod in the family Idoteidae. Its sole member is Glyptidotea lichtensteini, the keeled isopod, a medium-sized isopod found on the coast of southern Africa.
Brucerolis brandtae is a species of isopods in the family Serolidae, found in the Southern Ocean in the waters around New Zealand.
Brucerolis bromleyana is a benthic species of isopods in the family Serolidae, found in the Southern Ocean.
