Homarus is a genus of lobsters, which include the common and commercially significant species Homarus americanus and Homarus gammarus. The Cape lobster, which was formerly in this genus as H. capensis, was moved in 1995 to the new genus Homarinus.
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.
The velvet crab, or alternately velvet swimming crab, devil crab, “fighter crab”, or lady crab,Necora puber, is a species of crab from the North-East Atlantic and the Mediterranean. It is the largest of the swimming crab family (Portunidae) found in British coastal waters. It has a carapace width of up to 100 millimetres (3.9 in), and is the only species in the genus Necora. Its body is coated with short hairs, giving the animal a velvety texture, hence the common name. It is one of the major crab species for United Kingdom fisheries, in spite of its relatively small size.
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.
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.
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.
Scyllarides is a genus of slipper lobsters.
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.
Ibacus ciliatus is a species of slipper lobster from the north-west Pacific Ocean.
Jasus paulensis, also commonly known as the St Paul rock lobster, is a species of spiny lobster found in the waters around Saint Paul Island in the southern Indian Ocean and around Tristan da Cunha in the southern Atlantic Ocean. At one time the rock lobsters on Tristan da Cunha were believed to be a separate species known as the Tristan rock lobster, but the use of mitochondrial DNA sequencing has shown them to be identical. Some authorities, for example the International Union for Conservation of Nature, retain them as separate species. The Tristan rock lobster features on the coat of arms and the flag of Tristan da Cunha.
Chaceon is a crab genus in the family Geryonidae, and was first described in 1989 by Raymond Manning and Lipke Holthuis.
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.
Leptocarpus is a genus of shrimp belonging to the family Palaemonidae.
Creaseria is a genus of shrimps belonging to the family Palaemonidae.
Cryphiops is a genus of shrimp belonging to the family Palaemonidae.
