Sicyonia is a genus of prawns, placed in its own family, Sicyoniidae. [1] It differs from other prawns in that the last three pairs of its pleopods are uniramous, rather than biramous as seen in all other prawns. [2]

Sicyonia contains 52 extant species, [1] and one species known only from fossils [3] from the Upper Cretaceous. [4] Analyses using molecular phylogenetics suggest that the family Sicyoniidae is nested within the larger family Penaeidae, and that the latter family may need to be divided up, elevating each of its traditionally recognised tribes to the rank of family. [2]

The extant species are: [1]

Dendrobranchiata Suborder of prawns

Dendrobranchiata is a suborder of decapods, commonly known as prawns. There are 540 extant species in seven families, and a fossil record extending back to the Devonian. They differ from related animals, such as Caridea and Stenopodidea, by the branching form of the gills and by the fact that they do not brood their eggs, but release them directly into the water. They may reach a length of over 330 millimetres (13 in) and a mass of 450 grams (1.0 lb), and are widely fished and farmed for human consumption.

Decapoda Order of crustaceans

The Decapoda or decapods are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crabs, lobsters, crayfish, shrimp and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp and Anomura including hermit crabs, porcelain crabs, squat lobsters making up the bulk of the remainder. The earliest fossil decapod is the Devonian Palaeopalaemon.

Pleocyemata Suborder of crustaceans

Pleocyemata is a suborder of decapod crustaceans, erected by Martin Burkenroad in 1963. Burkenroad's classification replaced the earlier sub-orders of Natantia and Reptantia with the monophyletic groups Dendrobranchiata (prawns) and Pleocyemata. Pleocyemata contains all the members of the Reptantia, as well as the Stenopodidea, and Caridea, which contains the true shrimp.

Stenopodidea Infraorder of crustaceans

The Stenopodidea or boxer shrimps are a small group of decapod crustaceans. Often confused with Caridea shrimp or Dendrobranchiata prawns, they are neither, belonging to their own group.

Hippolytidae Family of crustaceans

Hippolytidae is a family of cleaner shrimp, also known as broken-back shrimp or anemone shrimp. The term "broken-back shrimp" also applies to the genus Hippolyte in particular and "cleaner shrimp" is sometimes applied exclusively to Lysmata amboinensis.

Penaeidae Family of crustaceans

Penaeidae is a family of marine crustaceans in the suborder Dendrobranchiata, which are often referred to as penaeid shrimp or penaeid prawns. The Penaeidae contain many species of economic importance, such as the tiger prawn, whiteleg shrimp, Atlantic white shrimp, and Indian prawn. Many prawns are the subject of commercial fishery, and farming, both in marine settings, and in freshwater farms. Lateral line–like sense organs on the antennae have been reported in some species of Penaeidae. At 210 metres per second (760 km/h), the myelinated giant interneurons of pelagic penaeid shrimp have the world record for impulse conduction speed in any animal.

<i>Palaemon</i> (shrimp) Genus of crustaceans

Palaemon is a genus of caridean shrimp of the family Palaemonidae. The conventional circumscription of the genus Palaemon is probably paraphyletic. Molecular data suggest that Palaemonetes, as well as the genera Exopalaemon and Couteriella, are nested within Palaemon. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments.

<i>Farfantepenaeus</i> Genus of crustaceans

Farfantepenaeus is a genus of prawns in the family Penaeidae. Its eight species were formerly included in the genus Penaeus. It was first published as a genus name in 1972 by Rudolf N. Burukovsky, but without the necessary designation of a type species. That situation was corrected by the same author in 1997. The name Farfantepenaeus commemorates the Cuban carcinologist Isabel Pérez Farfante.

<i>Actumnus</i> Genus of crabs

Actumnus is a genus of crabs in the family Pilumnidae. Alongside the 28 extant species, it has a fossil record extending back into the Miocene.

<i>Benthesicymus</i> Genus of crustaceans

Benthesicymus is a genus of prawns, containing the following species:

<i>Metapenaeopsis</i> Genus of crustaceans

Metapenaeopsis, the velvet shrimps, is a prawn genus in the family Penaeidae. It contains these species:

<i>Pandalus</i> Genus of crustaceans

Pandalus 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.

<i>Crangon</i> Genus of crustaceans

Crangon is a genus of shrimp.

<i>Litopenaeus</i> Genus of crustaceans

Litopenaeus is a genus of prawns, formerly included in the genus Penaeus. It contains five species:

<i>Trachysalambria</i> Genus of crustaceans

Trachysalambria is a genus of prawns, containing ten species. It was erected in 1934 by Martin Burkenroad, as a subgenus of Trachypenaeus, with T. curvirostris as its type species. That subgenus was elevated to the rank of genus in 1997 by Isabel Pérez Farfante and Brian Kensley. The ten species are:

Martin Burkenroad American marine biologist

Martin David Burkenroad was an American marine biologist. He specialized in decapod crustaceans and fisheries science.

Sicyonia ingentis is a species of prawn in the family Sicyoniidae known by the common name ridgeback prawn. It is native to the eastern Pacific Ocean, where it occurs along the coast of California and Baja California, its distribution extending from Monterey Bay to Isla María Madre off Nayarit. It also lives in the Gulf of California. Other common names include Pacific rock shrimp and Japanese shrimp. In Spanish it is called camarón de piedra del Pacífico and cacahuete.

Thoridae Family of crustaceans

Thoridae is a family of cleaner shrimp, also known as broken-back shrimp or anemone shrimp.

Aristeidae Family of crustaceans

Aristeidae is a family of Dendrobranchiata decapod crustaceans known as deep-sea shrimps, gamba prawns or gamba shrimps. Some species are subject to commercial fisheries.

<i>Solenocera</i> Genus of prawns

Solenocera is a genus of prawns in the family Solenoceridae. Solenocera occur from 0 to 2,067 meters deep in the ocean.
