Phreatoasellus is a genus of isopod crustaceans in the family Asellidae. It contains the following species: [1]
Genus Phreatoasellus contains the following species: [2]
Isopoda is an order of crustacean, which includes woodlice and their relatives. Members of this group are called Isopods and include both terrestrial and aquatic species. 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.
The Gnathiidae are a family of isopod crustaceans. They occur in a wide range of depths, from the littoral zone to the deep sea. The adults are associated with sponges and may not feed. The juvenile form is known as a 'praniza', and it is a temporary parasite of marine fish. These forms are not larvae; Gnathiidae instead become parasitic during the manca stage. Mancae of the Gnathiidae closely resemble the adult form, however they lack the final pair of pereiopods.
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.
Arubolana is a genus of crustacean in the family Cirolanidae, containing the following species:
Curassanthura is a genus of isopod crustaceans in the family Leptanthuridae. It contains the following species:
Monolistra is a genus of isopod crustaceans in the family Sphaeromatidae. Its members are restricted to countries of the former Yugoslavia, Italy and Switzerland. It contains the following subgenera and species, four of which are listed as vulnerable (VU) or endangered (EN) on the IUCN Red List:
Onchotelson is a genus of isopod crustaceans in the family Phreatoicidae, which is endemic to Tasmania. It contains two species, both of which are listed as vulnerable on the IUCN Red List:
Sphaerolana is a genus of isopod crustaceans in the family Cirolanidae, all of which are endemic to Mexico.
Thermosphaeroma is a genus of crustacean in family Sphaeromatidae. They occur exclusively in hot springs of southwestern United States and central Mexico.
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.
The Asellidae are a family of isopod crustaceans, one of the largest families of freshwater isopods, living in both epigean and hypogean habitats in North America and Europe.
The Leptanthuridae are a family of isopod crustaceans, containing the following genera:
Sphaeromatidea is a suborder of isopod crustaceans.
Asellus is a genus of isopod crustaceans in the family Asellidae.
Chiridotea is a genus of isopod crustaceans in the family Chaetiliidae, containing the following species:
Saduria is a genus of benthic isopod crustaceans in the family Chaetiliidae, containing the following species:
Dynoides is a genus of isopod crustaceans in the family Sphaeromatidae, containing the following species:
Synasellus is a genus of isopod crustaceans in the family Asellidae. It contains the following species:
Rhyscotus is a genus of armadillo woodlice, land crustacean isopods of the family Rhyscotidae. It was first described in 1885 by Gustav Budde-Lund.
Laureola is a genus of woodlice, a land crustacean isopod of the family Armadillidae.
