Metacrangon is a genus of shrimp belonging to the family Crangonidae. [1]
The genus has cosmopolitan distribution. [1]
There are a total of 46 species: [2]
King crabs are a taxon of decapod crustaceans that are chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food with the most common being the red king crab.
Xanthidae is a family of crabs known as gorilla crabs, mud crabs, pebble crabs or rubble crabs. Xanthid crabs are often brightly coloured and are highly poisonous, containing toxins which are not destroyed by cooking and for which no antidote is known. The toxins are similar to the tetrodotoxin and saxitoxin produced by puffer fish, and may be produced by bacteria in the genus Vibrio living in symbiosis with the crabs, mostly V. alginolyticus and V. parahaemolyticus.
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.
Athanas is a genus of shrimp of the family Alpheidae. These are small shrimp measuring 2 cm in length. Females have smaller chelae than males.
Pagurus is a genus of hermit crabs in the family Paguridae. Like other hermit crabs, their abdomen is not calcified and they use snail 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.
Potamonautes is a genus of African freshwater crabs in the family Potamonautidae. It is both the most widespread and most diverse genus of African freshwater crabs, including more than half the species of this continent. They are found in most freshwater habitats of the African mainland and some species are semi-terrestrial.
Eiconaxius is a genus of mud lobster that includes the following species:
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:
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).
Pugettia is a genus of kelp crabs in the family Epialtidae. It comprises the following species:
Uroptychus is a genus of squat lobsters in the family Chirostylidae found across the Indo-Pacific. The genus Uroptychus contains the following species:
Leucosiidae is a family of crabs containing three subfamilies and a number of genera incertae sedis:
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.
Cyclograpsus is a genus of crabs, containing the following species:
Hyastenus is a genus of crabs in the family Epialtidae, subfamily Pisinae, containing the following extant species:
Ebalia is a genus of crab in the family Leucosiidae.
Heptacarpus is a genus of shrimps in the family Thoridae. There are more than 30 described species in the genus Heptacarpus.
Neocrangon is a genus of crustaceans belonging to the family Crangonidae.
