Malacostraca Largest class of crustaceans

Malacostraca is the largest of the six classes of crustaceans, containing about 40,000 living species, divided among 16 orders. Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, amphipods, mantis shrimp and many other, less familiar animals. They are abundant in all marine environments and have colonised freshwater and terrestrial habitats. They are segmented animals, united by a common body plan comprising 20 body segments, and divided into a head, thorax, and abdomen.

Gonopore Invertebrate genital pore

A gonopore, sometimes called a gonadopore, is a genital pore in many invertebrates. Hexapods, including insects have a single common gonopore, except mayflies, which have a pair of gonopores. More specifically, in the unmodified female it is the opening of the common oviduct, and in the male, it is the opening of the ejaculatory duct.

Leptostraca Extinct order of crustaceans

Leptostraca is an order of small, marine crustaceans. Its members, including the well-studied Nebalia, occur throughout the world's oceans and are usually considered to be filter-feeders. It is the only extant order in the subclass Phyllocarida. They are believed to represent the most primitive members of their class, the Malacostraca, and first appear in the fossil record during the Cambrian period.

Eucarida Superorder of crustaceans

Eucarida is a superorder of the Malacostraca, a class of the crustacean subphylum, comprising the decapods, krill, Amphionides and Angustidontida. They are characterised by having the carapace fused to all thoracic segments, and by the possession of stalked eyes.

Phyllocarida Subclass of crustaceans

Phyllocarida is a subclass of crustaceans, comprising the extant order Leptostraca and the extinct orders Hymenostraca and Archaeostraca.

Peracarida Order of crustaceans

The superorder Peracarida is a large group of malacostracan crustaceans, having members in marine, freshwater, and terrestrial habitats. They are chiefly defined by the presence of a brood pouch, or marsupium, formed from thin flattened plates (oostegites) borne on the basalmost segments of the legs. Peracarida is one of the largest crustacean taxa and includes about 12,000 species. Most members are less than 2 cm (0.8 in) in length, but the largest is probably the giant isopod which can reach 76 cm (30 in). The earliest known perecaridian was Oxyuropoda ligioides, a fossil of which has been found dating to the Late Devonian of Ireland.

Cumacea Order of crustacean

Cumacea is an order of small marine crustaceans of the superorder Peracarida, occasionally called hooded shrimp or comma shrimp. Their unique appearance and uniform body plan makes them easy to distinguish from other crustaceans. They live in soft-bottoms such as mud and sand, mostly in the marine environment. There are more than 1,500 species of cumaceans formally described. The species diversity of Cumacea increases with depth.

Edriophthalma is a disused peracarid (Malacostraca) classification comprising Isopoda and Amphipoda, first proposed by William Elford Leach in 1815. They have several common features, such as the fact that they both lack a carapace, possess sessile compound eyes, and thoracic coxae fused to their pleurites. Some molecular studies have shown that these are not related. The group has also been known as Acaridea and Arthrostraca.

<i>Bellia</i> Genus of crabs

Bellia picta is a species of crab that lives around the coasts of South America, and the only species in the genus Bellia. On the Atlantic coast, it is found in Rio Grande do Sul, Brazil, while on the Pacific coast, it is found off Peru and Chile. It probably lives in burrows and is a filter feeder.

<i>Alope</i> (crustacean) Genus of crustaceans

Alope is a genus of shrimp in the family Hippolytidae, comprising two species:

Phylogeny of Malacostraca is the evolutionary relationships of the largest of the six classes of crustaceans, containing about 40,000 living species, divided among 16 orders. Its members display a great diversity of body forms. Although the class Malacostraca is united by a number of well-defined and documented features, which were recognised a century ago by William Thomas Calman in 1904, the phylogenetic relationship of the orders which compose this class is unclear due to the vast diversity present in their morphology. Molecular studies have attempted to infer the phylogeny of this clade, resulting in phylogenies which have a limited amount of morphological support. To resolve a well-supported eumalacostracan phylogeny and obtain a robust tree, it will be necessary to look beyond the most commonly utilized sources of data.

Stenopodidae Family of crustaceans

Stenopodidae is a family of decapods in the order Decapoda. There are about 6 genera and more than 30 described species in Stenopodidae.

<i>Hymenodora</i> Genus of crustaceans

Hymenodora is a genus of shrimp, containing four species, which collectively have a southern circumpolar distribution.

Dorphinaxius kermadecensis is a genus of mud lobster native to the Norfolk Island, parts of New South Wales, and the Kermadec Islands of New Zealand. It is the only species in the genus Dorphinaxius. It has a depth range of 0–8 metres (0–26 ft).

Crustacean Subphylum of arthropods

Crustaceans form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustaceans. Some crustaceans are more closely related to insects and the other hexapods than they are to certain other crustaceans.

Armadillidae Family of woodlice

Armadillidae is a family of woodlice, comprising around 80 genera and 700 species. It is the largest family of Oniscidea, and one of the most species-rich families of the entire Isopoda. Armadillids generally have a strongly convex body shape, with some rather shallowly convex. Like members of the woodlice family Armadillidiidae, armadillids are capable of enrolling into a sphere (conglobation), and are commonly known as pill bugs. Armadillids differ from the Armadillidiidae in that the antennae are fully enclosed within the sphere.

<i>Bathynectes piperitus</i> Species of crustacean

Bathynectes piperitus is a species of crab in the family Polybiidae. It is found in Angola, Cabinda, Cape Verde, Fao Fishing Area, Gabon, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Senegal, and West Africa.

Detonidae Family of crustaceans

Detonidae is a family of woodlice in the order Isopoda. There are at least 3 genera and more than 30 described species in Detonidae.

Siriella is a genus of mysid crustaceans form the family Mysidae, consisting of approximately 90 species. Found in all seas except cold Arctic and Antarctic waters, the genus is most diverse in tropics.

Bathyporeiidae Family of crustaceans

Bathyporeiidae is a family of amphipods in the order Amphipoda. There are two genera in Bathyporeiidae:
