Heptacarpus is a genus of shrimps in the family Thoridae. There are more than 30 described species in the genus Heptacarpus. [1] [2]
The following species are recognised in the genus Heptacarpus: [3]
Pinnotheres is a genus of crabs, including the pea crab. Many species formerly in Pinnotheres have been placed in new genera, such as Zaops ostreus, the oyster crab and Nepinnotheres novaezelandiae, the New Zealand pea crab. The species currently recognised in the genus Pinnotheres are:
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.
Alpheopsis is a genus of shrimp of the family Alpheidae. Several species of the genus have been known to share the same burrows with members of different species. They are inhabitants of the eastern Pacific Ocean.
Synalpheus is a genus of snapping shrimp of the family Alpheidae, presently containing more than 100 species; new ones are described on a regular basis, and the exact number even of described species is disputed.
Ozius is a genus of crabs in the family Menippidae, containing the following species:
Syncaris is a genus of shrimp, containing only two species: the endangered California freshwater shrimp, Syncaris pacifica, and the extinct Pasadena freshwater shrimp, Syncaris pasadenae. This genus is one of only two genera of freshwater Atyid shrimp found in North America, with the other being the genus Palaemonias, which contains two endangered, cave-dwelling shrimp species. The genus Syncaris may have arisen during the Mesozoic, with the family Atyidae likely being of Jurassic origin.
Hippolyte is a genus of shrimp of the family Hippolytidae, containing the following species:
Palaemon is a genus of caridean shrimp in the family Palaemonidae.
Lebbeus is a genus of shrimp in the family Thoridae. It includes a species whose name was auctioned in 2009 to raise funds for conservation; Luc Longley won with a bid of A$3,600. He named the shrimp Lebbeus clarehannah. The following species are included:
Lysmata is a genus of shrimp in the infraorder Caridea, the caridean shrimp. The genus belongs to the family Lysmatidae. Lysmata are popular ornamental shrimp in the marine aquarium trade for their bright color patterns, interesting behaviors, and ability to control certain aquarium pests such as sea anemones of the genus Aiptasia. They are known to command high prices on the pet market.
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.
Pilumnus is a genus of crabs, containing the following species:
Crangon is a genus of shrimp.
The Panopeidae are a family containing 26 genera of morphologically similar crabs, often known as "mud crabs". Their centers of diversity are the Atlantic Ocean and eastern Pacific Ocean.
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:
Leptochela is a genus of small 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.
Pachycheles is a genus of porcelain crabs in the family Porcellanidae. There are more than 40 described species in Pachycheles.
Periclimenes, commonly known as glass shrimp or cleaner shrimp, is a commensal and often symbiotic genus of semi-transparent shrimp within the family Palaemonidae. Species of this large genus feature a wide variety of coloration and patterns, widespread distribution throughout much of the world's tropical oceans, and are often sought out for aquarium trade.
