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.
The family Polychelidae contains thirty-eight extant species of blind, benthic lobster-like crustaceans. They are found throughout the world's tropical, sub-tropical and temperate oceans, including the Mediterranean Sea and the Irish Sea.
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.
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.
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.
Acanthacaris is a genus of deep-water lobsters. It contains two species, A. caeca and A. tenuimana, and is the only genus in the subfamily Neophoberinae.
Munidopsis is a genus of squat lobster. It is the second largest of all the genera of squat lobsters, after Munida, with over 200 species. Its members are mainly found on continental slopes and on abyssal plains. A few fossil species are also known, including specimens from the Campanian (Cretaceous).
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.
Metapenaeopsis, the velvet shrimps, is a prawn genus in the family Penaeidae. It contains these species:
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.
Sicyonia is a genus of prawns, placed in its own family, Sicyoniidae. 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.
Juxtastenopus spinulatus is a species of stenopodidean shrimp. It lives in the Red Sea, and across the Indian Ocean as far east as the Philippines. It is red or pink, up to 28 mm (1.1 in) long, with enlarged third pereiopods. Originally described in the genus Engystenopus, it is now placed in the monotypic genus Juxtastenopus, in the family Stenopodidae.
Nephropsis is a genus of lobsters containing 15 extant species:
Ancylomenes is a genus of shrimp, erected in 2010 to accommodate the group of species around "Periclimenes aesopius". Members of the genus are widely distributed in the warm oceans of the world, and live in association with cnidarians; most are cleaner shrimp.
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.
Solenoceridae is a family of decapods, containing 10 genera. Members of this family are marine, inhabiting shallow and offshore waters from the mid-continental shelf, ranging from depths to 1000 meters deep. Members of this family are also sometimes confused with other commercial shrimp species.
Hymenopenaeus is a genus of prawns containing 17 species.
Solenocera is a genus of prawns in the family Solenoceridae. Solenocera occur from 0 to 2,067 meters deep in the ocean.
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.
