Caridea

The Caridea, commonly known as caridean shrimp or true shrimp (from Ancient Greek καρίς, καρίδος (karís, karídos, "shrimp"), are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.

Atyidae is a family of shrimp, present in all tropical and most temperate waters of the world. Adults of this family are almost always confined to fresh water. This is the only family in the superfamily Atyoidea.

The family Pandalidae is a taxon of caridean shrimp. These species are commonly called pandalid shrimp. They are edible and have high economic value. They are characterised by the subdivided carpus of the second pereiopod and, mainly, by the lack of the chelae (claws) on the first pereiopod. This is a cold-water family, and their representation in tropical areas is made by deep-sea shrimp. The genus Physetocaris, sometimes placed in this family, is now considered to be in its own family, Physetocarididae.

Palaemonoidea is a large superfamily of shrimp, containing nearly 1,000 species. The position of the family Typhlocarididae is unclear, although the monophyly of a group containing the remaining seven families is well supported.

Crangonidae is a family of shrimp, of the superfamily Crangonoidea, including the commercially important species Crangon crangon. Its type genus is Crangon. Crangonid shrimps' first pair of pereiopods have partially chelate claws that they use to capture their prey. They burrow shallowly into sediment on the sea floor, and feed on bivalves, crustaceans, polychaetes, and some small fish.

Neocaridina is a genus of small, land-locked freshwater shrimp in the family Atyidae (order Decapoda, infraorder Caridea) native to East Asia. The genus comprises roughly c. 25–30 described species (numbers vary with ongoing revision and differing treatments of synonyms and subspecies).

Alpheoidea is a superfamily of shrimp. Species of shrimp in the superfamily Alpheoidea are drag swimmers, as opposed to lift swimmers.

Pandalus (cold-water prawn) is a genus of shrimp in the family Pandalidae. Members of the genus are medium-sized and live on or near the seabed. Some species are the subject of commercial fisheries and are caught by trawling. One species, Pandalus montagui, lives in association with the reef-building polychaete worm, Sabellaria spinulosa.

Pasiphaeidae is a family of shrimp. It is the only family in the superfamily Pasiphaeoidea and contains seven extant genera: Alainopasiphaea Hayashi, 1999 Eupasiphae Wood-Mason, 1893 Glyphus Filhol, 1884 Leptochela Stimpson, 1860 Parapasiphae Smith, 1884 Pasiphaea Savigny, 1816 Psathyrocaris Wood-Mason, 1893

The Pandaloidea are a superfamily of shrimp, comprising the large family Pandalidae (about 200 species) and the much smaller Chlorotocellidae (seven species).

Crangonoidea is a superfamily of shrimp containing the two families Crangonidae and Glyphocrangonidae.

The family Oplophoridae is a taxon of pelagic shrimp and the only subtaxon of the superfamily Oplophoroidea. It contains the following genera: Acanthephyra A. Milne-Edwards, 1881 Ephyrina Smith, 1885 Heterogenys Chace, 1986 Hymenodora Sars, 1877 Janicella Chace, 1986 Kemphyra Chace, 1986 Meningodora Smith, 1882 Notostomus A. Milne-Edwards, 1881 † Odontochelion Garassino, 1994 Oplophorus H. Milne-Edwards, 1837 Systellaspis Bate, 1888 † Tonellocaris Garassino, 1998

The family Rhynchocinetidae are a group of small, reclusive red-and-white shrimp. This family typically has an upward-hinged foldable rostrum, hence its taxon name Rhynchocinetidae, which means movable beak; this gives these shrimps their common name of hinge-beak shrimps. The family contains only two genera, Cinetorhynchus and Rhynchocinetes.

Alvinocarididae is a family of shrimp, originally described by M. L. Christoffersen in 1986 from samples collected by DSV Alvin, from which they derive their name. Shrimp of the family Alvinocarididae generally inhabit deep sea hydrothermal vent regions, and hydrocarbon cold seep environments. Carotenoid pigment has been found in their bodies. The family Alvinocarididae comprises 7 extant genera.

Heterocarpus is a genus of deep-sea shrimp, mainly of tropical areas all over the world.

The Processidae are a family of shrimp, comprising 65 species in five genera, and the only family in the superfamily Processoidea. They are small, nocturnal animals, mostly living in shallow seas, particularly on grass flats. The first pereiopods are usually asymmetrical, with a claw on one, but not the other (Ambidexter forming the exception to this rule). The rostrum is generally a simple projection from the front of the carapace, with two teeth, one at the tip, and one further back.

Bresilioidea is a superfamily of shrimp. It is likely to be an artificial group, containing five families which may or may not be related.

The family Stylodactylidae is a group of shrimp and the only representative of its superfamily (Stylodactyloidea). It contains the five genera Bathystylodactylus, Neostylodactylus, Parastylodactylus, Stylodactyloides and Stylodactylus.

Nematocarcinoidea is a superfamily of caridean shrimp, comprising five families – Eugonatonotidae, Lipkiidae, Nematocarcinidae, Rhynchocinetidae, and Xiphocarididae. Their shared feature is the presence of strap-like epipods on at least the first three pairs of pereiopods, and a blunt molar process.

Campylonotoidea is a superfamily of shrimp, containing the two families Campylonotidae and Bathypalaemonellidae. Fenner A. Chace considered it to be the sister group to the much larger superfamily Palaemonoidea, with which it shares the absence of endopods on the pereiopods, and the fact that the first pereiopod is thinner than the second. Using molecular phylogenetics, Bracken et al. proposed that Campylonotoidea may be closer to Atyoidea. There are sixteen described species in 3 genera; no fossils are known.

Acanthephyra is a genus of shrimp in the family Acanthephyridae, with species that live at depths from 0 to more than 5000 meters deep below the ocean surface.

Glyphocrangonidae is a family of crustaceans belonging to the order Decapoda.

Rhynchocinetes is a genus of shrimp, containing the following 14 species:

Leptochela is a genus of small, shallow-water shrimp from the family Pasiphaeidae. They are found in the Indo-Pacific region and the western Atlantic with an isolated species in Hawaii, they are absent from the eastern Atlantic Ocean and were absent from the eastern Pacific but specimens of a species widespread in the western Atlantic were collected from waters to the south of the tip of Baja California. Two species, Leptochela aculeocaudata and Leptochela pugnax have invaded the eastern Mediterranean from the Red Sea through the Suez Canal and are thus classified as Lessepsian migrants.

Cinetorhynchus is a genus of shrimp in the family Rhynchocinetidae. It was originally described in 1995 by Lipke Holthuis as a subgenus of the genus Rhynchocinetes, but was elevated to the rank of genus by Okuno in 1997. Both genera share the characteristic jointed rostrum, but differ in the numbers and positions of various spines. Cinetorhynchus contains the following species: Cinetorhynchus brucei Okuno, 2009 Cinetorhynchus concolor (Okuno, 1994) Cinetorhynchus erythrostictus Okuno, 1997 Cinetorhynchus fasciatus Okuno & Tachikawa, 1997 Cinetorhynchus gabonensis Ďuriš, Šobáňová & Wirtz, 2019

Atyoida is a genus of freshwater shrimp in the family Atyidae. There are five species in the genus, each endemic to a different Pacific island group. The type species, Atyoida bisulcata, is endemic to Hawaiʻi and described by John Witt Randall in 1840.

Nematocarcinus, sometimes known as spider shrimp, is a genus of caridean shrimp, the nominotype of Nematocarcinidae. Similar to the other members of their family, Nematocarcinus inhabit the deep sea, walking on the seabed with their specialized, extremely elongate legs (the pereiopods). Despite continuing fisheries experiments, they are currently not commercially fished, but often appear as bycatch.

Eugonatonotus is a genus of decapods and is the only genus in the monotypic family Eugonatonotidae.

Amphionides reynaudii is a species of caridean shrimp, whose identity and position in the crustacean system remained enigmatic for a long time. It is a small (less than one inch long) planktonic crustacean found throughout the world's tropical oceans, which until 2015 was considered the sole representative of the order Amphionidacea, due to unusual morphological features. Molecular data however confirm it as a member of the caridean family Pandalidae, and the confusion of morphology is because only larval phases have so far been studied.
