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.
Reef lobsters, Enoplometopus, are a genus of small lobsters that live on reefs in the Indo-Pacific, Caribbean and warmer parts of the Atlantic Ocean.
Atyidae is a family of shrimp, present in all tropical and most temperate waters of the world. Adults of this family are almost always confined to fresh water. This is the only family in the superfamily Atyoidea.
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.
Palaemonidae is a family of shrimp in the order Decapoda. Many species are carnivores that eat small invertebrates, and can be found in any aquatic habitat except the deep sea. One significant genus is Macrobrachium, which contains commercially fished species. Others inhabit coral reefs, where they associate with certain invertebrates, such as sponges, cnidarians, mollusks, and echinoderms, as cleaner shrimps, parasites, or commensals. They generally feed on detritus, though some are carnivores and hunt tiny animals.
Palaemon is a genus of caridean shrimp in the family Palaemonidae.
Iais is a genus of isopod crustaceans. Iais species are found in association with larger isopods of the family Sphaeromatidae, usually on the ventral surface of the larger animal, between the pereiopods and on the pleopods. They are native to Australasia and South America, although Iais californica and its host Sphaeroma quoyanum have invaded California, and I. californica was first described from Sausalito, California. Nine species are recognised:
Scyllarides is a genus of slipper lobsters.
Fenner Albert Chace Jr. was an American carcinologist.
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:
Arctides is a genus of slipper lobsters, containing three species. The largest of these, A. antipodarum, has a carapace up to 100 millimetres (3.9 in) long, and is found off south-eastern Australia and parts of New Zealand. The other two species are smaller, at up to 70 millimetres (2.8 in) carapace length; A. guineensis is found in an area similar to the Bermuda Triangle; A. regalis is widely distributed in the Indo-Pacific, from the Mascarene Islands to Hawaii and Easter Island.
Macrobrachium is a genus of freshwater prawns or shrimps characterised by the extreme enlargement of the second pair of pereiopods, at least in the male.
Macropodia is a genus of crabs, belonging to the family Inachidae. It contains the following species:
Inachus is a genus of crab, containing the following species:
Palaemonella is a genus of shrimp in the family Palaemonidae, containing the following species:
Chaceon is a crab genus in the family Geryonidae, and was first described in 1989 by Raymond Manning and Lipke Holthuis.
Periclimenaeus is a genus of decapod crustaceans of the family Palaemonidae which is part of the infraorder Caridea. The genus was named by the English carcinologist Lancelot Alexander Borradaile in 1915. He set out the distinguishing features of the genus as:
Body rather stout, cephalothorax deep, a good deal compressed, abdomen greatly curved Thorax without dorsal swelling. Rostrum rather short, compressed, toothed above only. Outer antennular flagellum not deeply cleft. Antennal scale of good breadth. Mandible without palp. Second maxilliped without podopalp. Third maxilliped narrow, with vestigial arthrobranch.
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.
Pontonia is a genus of shrimps belonging to the family Palaemonidae.
