Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, craybobs, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as Procambarus clarkii, are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus.
Spiny lobsters, also known as langustas, langouste, or rock lobsters, are a family (Palinuridae) of about 60 species of achelate crustaceans, in the Decapoda Reptantia. Spiny lobsters are also, especially in Australia, New Zealand, Ireland, South Africa, and The Bahamas, called crayfish, sea crayfish, or crawfish, terms which elsewhere are reserved for freshwater crayfish.
The California spiny lobster is a species of spiny lobster found in the eastern Pacific Ocean from Monterey Bay, California, to the Gulf of Tehuantepec, Mexico. It typically grows to a length of 30 cm (12 in) and is a reddish-brown color with stripes along the legs, and has a pair of enlarged antennae but no claws. The interrupted grooves across the tail are characteristic for the species.
Jasus edwardsii, the southern rock lobster, red rock lobster, or spiny rock lobster, is a species of spiny lobster found throughout coastal waters of southern Australia and New Zealand including the Chatham Islands. It is commonly called crayfish in Australia and New Zealand and kōura in Māori. They resemble lobsters, but lack the large characteristic pincers on the first pair of walking legs.
Lobsters are widely fished around the world for their meat. They are often hard to catch in large numbers, but their large size can make them a profitable catch. Although the majority of the targeted species are tropical, the majority of the global catch is in temperate waters.
Panulirus cygnus is a species of spiny lobster, found off the west coast of Australia. Panulirus cygnus is the basis of Australia's most valuable fishery, making up 20% of value of Australia's total fishing industry, and is identified as the western rock lobster.
Palibythus magnificus, sometimes called the musical furry lobster, is a species of furry lobster found in Polynesia. It is generally included in the family Palinuridae, although it has also been separated from that family with the genus Palinurellus to form the family Synaxidae in the past. The species is known in Samoan as ula moana, a name which also covers the deep-water shrimp Heterocarpus laevigatus.
Ibacus peronii, the Balmain bug or butterfly fan lobster, is a species of slipper lobster. It lives in shallow waters around Australia and is the subject of small-scale fishery. It is a flattened, reddish brown animal, up to 23 cm (9 in) long and 14 cm (6 in) wide, with flattened antennae and no claws.
Palinurus elephas is a commonly caught species of spiny lobster from the East Atlantic Ocean and the Mediterranean Sea. Its common names include European spiny lobster, crayfish or cray, crawfish, common spiny lobster, Mediterranean lobster and red lobster.
Panulirus versicolor is a species of spiny lobster that lives in tropical reefs in the Indo-Pacific. Other names include painted rock lobster, common rock lobster, bamboo lobster, blue lobster, and blue spiny lobster. P. versicolor is one of the three most common varieties of spiny lobster in Sri Lanka, alongside Panulirus homarus and Panulirus ornatus.
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.
Jasus lalandii, the Cape rock lobster or West Coast rock lobster, is a species of spiny lobster found off the coast of Southern Africa. It is not known whom the specific epithet lalandii commemorates, although it may the French naturalist and taxonomer Pierre Antoine Delalande.
Scyllarides latus, the Mediterranean slipper lobster, is a species of slipper lobster found in the Mediterranean Sea and in the eastern Atlantic Ocean. It is edible and highly regarded as food, but is now rare over much of its range due to overfishing. Adults may grow to 1 foot (30 cm) long, are camouflaged, and have no claws. They are nocturnal, emerging from caves and other shelters during the night to feed on molluscs. As well as being eaten by humans, S. latus is also preyed upon by a variety of bony fish. Its closest relative is S. herklotsii, which occurs off the Atlantic coast of West Africa; other species of Scyllarides occur in the western Atlantic Ocean and the Indo-Pacific. The larvae and young animals are largely unknown.
Panulirus pascuensis is a species of spiny lobster found around Easter Island and the Pitcairn Islands in the Pacific Ocean. It is known in English as the Easter Island spiny lobster, Langosta de Isla de Pascua in Spanish and Ura in the Rapa Nui language. This lobster is fished on a small scale for local consumption.
Panulirus homarus is a species of spiny lobster that lives along the coasts of the Indian and Pacific Oceans. It lives in shallow water, and feeds on the brown mussel Perna perna. It typically grows to a length of 20–25 cm (7.9–9.8 in). Alongside the dark green nominate subspecies, two red subspecies are recognised, one around the Arabian Peninsula, and one around southern Africa. It is the subject of small-scale fishery.
Jasus caveorum is a species of spiny lobster found on a single seamount in the southeastern Pacific Ocean, discovered in 1995 by fishermen from New Zealand. It is most similar to Jasus frontalis from the nearby Juan Fernández Islands, but is more closely related to species from the Atlantic and Indian Oceans.
Panulirus ornatus is a large edible spiny lobster with 11 larval stages that has been successfully bred in captivity.
Jasus frontalis, known as the Juan Fernández rock lobster, is a species of spiny lobster in the genus Jasus, found around the Juan Fernández and Desventuradas Islands in the south-eastern 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.
Panulirus penicillatus is a species of spiny lobster that lives on shallow rocky and coral reefs in the tropical Indo-Pacific region. Common names for this spiny lobster include variegated crayfish, tufted spiny lobster, spiny lobster, Socorro spiny lobster, red lobster, pronghorn spiny lobster, golden rock lobster, double spined rock lobster and coral cray. It has a very wide range and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
