Branchiopoda is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Diplostraca, Notostraca, the Devonian Lepidocaris and possibly the Cambrian Rehbachiella. They are mostly small, freshwater animals that feed on plankton and detritus.
Isopoda is an order of crustaceans. Members of this group are called isopods and include both aquatic species, and terrestrial species such as woodlice. 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 called the marsupium.
Prof Georg Ossian Sars HFRSE was a Norwegian marine and freshwater biologist.
Ligia oceanica, the sea slater, common sea slater, or sea roach, is a woodlouse, living in the littoral zone—rocky seashores of the European North Sea and Atlantic coastlines.
Mexistenasellus is a genus of isopod crustaceans in the family Stenasellidae.
Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects.
The Diplostraca or Cladocera, commonly known as water fleas, is a superorder of small, mostly freshwater crustaceans, most of which feed on microscopic chunks of organic matter, though some forms are predatory.
Asellota is a suborder of isopod crustaceans found in marine and freshwater environments. Roughly one-quarter of all marine isopods belong to this suborder. Members of this suborder are readily distinguished from other isopods by their complex copulatory apparatus. Other characteristics include six-jointed antennal peduncle, the styliform uropods, the fusion of pleonites 5, 4 and sometimes 3 to the pleotelson, and absence of the first pleopod in females.
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.
Oenopota is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae.
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.
Janiridae is a family of isopods in the suborder Asellota. There are more than 20 genera in Janiridae.
Idotea neglecta is a marine isopod in the family Idoteidae. It can be found on algae in the littoral and sublittoral zone of north-west European coasts.
Cercopagididae is a family of crustaceans belonging to the order Diplostraca. A lot of Cercopagididae species are non-native species, many of which pose a great threat to aquatic ecosystems.
Dendrotionidae is a family of marine isopods belonging to the suborder Asellota.
Desmosomatidae is a family of isopods belonging to the suborder Asellota.
Nannoniscidae is a family of crustaceans belonging to the order Isopoda. The family is closely related to Desmosomatidae, with multiple genera unidentifiable to family level due to containing attributes of both families.
Stenetriidae is a family of crustaceans belonging to the order Isopoda. They can be found in both tropical and polar waters.
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:
Iais chilense is a species of marine isopod in the family Janiridae. It was first described as Neoecitas chilense, before it was moved to the genus Iais. It is among the few members of Iais which do not live commensally with sphaeromatid isopods, and are instead found living near sea level in cracks or crevices.
