Decapod genera

Ocypode is a genus of ghost crabs found in the sandy shores of tropical and subtropical regions throughout the world. They have a box-like body, thick and elongated eyestalks, and one claw is larger than the other in both males and females. They inhabit deep burrows in the intertidal zone. They are primarily nocturnal, and are generalist scavengers and predators of small animals. The genus contains 21 species.

Panulirus is a genus of spiny lobsters in the family Palinuridae, including those species which have long flagella on their first antennae.

Astacus (from the Greek , '''', meaning "lobster" or "crayfish") is a genus of crayfish found in Europe, comprising three extant (living) species and three somewhat contested extinct species. These crayfish are found across Europe and live exclusively in freshwater, mostly inhabiting the bottom of lakes, ponds, and streams.

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).

Callinectes (from Ancient Greek κάλλος (kállos), meaning "beautiful", and νήκτης (nḗktēs), meaning "swimmer") is a genus of crabs containing species such as the Atlantic blue crab C. sapidus.

Pagurus is a genus of hermit crabs in the family Paguridae. Like other hermit crabs, their abdomen is not calcified and they use gastropod shells as protection. These marine decapod crustaceans are omnivorous, but mostly prey on small animals and scavenge carrion. Trigonocheirus and Pagurixus used to be considered subgenera of Pagurus, but the former is nowadays included in Orthopagurus, while the latter has been separated as a distinct genus.

Grapsus is a genus of lightfoot crabs, comprising the following species: Grapsus albolineatus Latreille in Milbert, 1812 Grapsus adscensionis (Osbeck, 1765) Grapsus fourmanoiri Crosnier, 1965 Grapsus grapsus (Linnaeus, 1758) Grapsus granulosus Milne-Edwards, 1853 Grapsus intermedius De Man, 1888 Grapsus longitarsis Dana, 1851 Grapsus tenuicrustatus (Herbst, 1783)

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.

Mictyris is a genus of brightly coloured crabs, placed in its own taxonomical family, the Mictyridae. It inhabits the central Indo-West Pacific region. These crabs congregate on mud flats or beaches in groups of a few thousand, and filter sand or mud for microscopic organisms. They congregate during low tide, and bury themselves in the sand during high tide or whenever they are threatened. This is done in wet sand, and they dig in a corkscrew pattern, leaving many small round pellets of sand behind them.

Portunus is a genus of crabs which includes several important species for fisheries, such as the blue swimming crab and the Gazami crab. Other species, such as the three-spotted crab are caught as bycatch. thumb|250px|right|Fossil of Portunus convexus

Lithodes is a genus of king crabs. Today there are about 30 recognized species, but others formerly included in this genus have been moved to Neolithodes and Paralomis. They are found in oceans around the world, ranging from shallow to deep waters, but mostly at depths of . They are restricted to relatively cold waters, meaning that they only occur at high depths at low latitudes, but some species also shallower at high latitudes. They are medium to large crabs, and some species are or were targeted by fisheries.

Clibanarius is a genus of hermit crabs in the family Diogenidae. Like other hermit crabs, their abdomen is soft-shelled and sheltered in a gastropod shell. Typically marine like all their relatives, the genus includes C. fonticola, the only known hermit crab species that spends all its life in freshwater. The feeding rates of Clibanarius species change with temperature which, given their broad distributions, may have considerable consequences for the stability reef systems as sea temperatures rise in the future.

Paralithodes is a genus of king crabs native to cold waters in the North Pacific Ocean, Okhotsk Sea, Bering Sea and Sea of Japan, but with one species also introduced to far northern Europe. They are medium-large to very large king crabs, and some species are important to commercial fisheries. A 2017 examination of the phylogeny of king crabs suggests that the internal placement of Paralithodes within this family is not fully resolved.

Pachygrapsus is a genus of small shore crabs. Recent genetic data suggest this genus to be possibly polyphyletic.

Eriphia is a genus of marine crabs in the family Eriphiidae. These crabs are common in most temperate and tropical seas.

Scyllarus is a genus of slipper lobsters from the Atlantic Ocean, including the Mediterranean and Caribbean. Until 2002, the genus included far more species, but these are now placed in other genera. The following species remain in Scyllarus:

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.

Cherax, commonly known as yabby/yabbies in Australia, is the most widespread genus of fully aquatic crayfish in the Southern Hemisphere. Various species of cherax may be found in both still and flowing bodies of freshwater across most of Australia and New Guinea. Together with Euastacus, it is also the largest crayfish genus in the Southern Hemisphere.

Cambarellus is a genus of small freshwater crayfish in the family Cambaridae. The 19 species are found in Mexico (subgenus Cambarellus) and the Gulf States of the United States (subgenus Pandicambarus). Among the Mexican species, C. areolatus, C. patzcuarensis, and C. prolixus are considered seriously threatened by the IUCN, and C. alvarezi is already extinct. C. chihuahuae was also believed to be extinct until rediscovered in 2012. C. alvarezi and four undescribed, extinct Cambarellus species were restricted to desert spring systems in southwestern Nuevo León; each one shared its habitat with

Potamon is a genus of freshwater or semiterrestrial crabs mainly found from Southern Europe through the Middle East, and as far east as north-western India. The only exception is the North African P. algeriense, which also is the only potamid of mainland Africa. Twenty species are currently recognised. These crabs are omnivores that have a broad ecological tolerance. The adult Potaman reach up to 50 mm in size during their 10-12 year life span.

It is one of the largest genera of squat lobsters that in 2008 contained 73 species (17 in the Atlantic Ocean, 25 in the Indian Ocean and 43 in the Pacific Ocean) (several more have been described more recently). Most species of Galathea live in shallow waters.

Three of the species in this genus (C. candida, C. tyrrhena and C. whitei) have been split off into a new genus, Pestarella, while others such as Callianassa filholi have been moved to Biffarius. The genus is named after the Nereid of the Greco-Roman mythology.

Austropotamobius is a genus of European crayfish in the family Astacidae. It contains four extant species,

Jasus is a genus of spiny lobsters which live in the oceans of the Southern Hemisphere. They have two distinct "horns" projecting from the front of the carapace, but lack the stridulating organs present in almost all other genera of spiny lobsters. Like all spiny lobsters, they lack claws, and have long stout antennae which are quite flexible.

Nephrops is a genus of lobsters comprising a single extant species, Nephrops norvegicus (the Norway lobster or Dublin Bay prawn), and several fossil species. It was erected by William Elford Leach in 1814, to accommodate N. norvegicus alone, which had previously been placed in genera such as Cancer, Astacus or Homarus. The genus name Nephrops comes from Ancient Greek νεφρός (nephrós), meaning "kidney", and ὄψ (óps), meaning "eye", and refers to the shape of the animal's compound eye.
