Astacus astacus, the European crayfish, noble crayfish, or broad-fingered crayfish, is the most common species of crayfish in Europe, and a traditional food source. Like other true crayfish, A. astacus is restricted to fresh water, living only in unpolluted streams, rivers, and lakes.

Cancer pagurus, commonly known as the edible crab or brown crab, is a species of crab found in the North Sea, North Atlantic Ocean and perhaps in the Mediterranean Sea. It is a robust crab of a reddish-brown colour, having an oval carapace with a characteristic "pie crust" edge and black tips to the claws.
Prawn vs Crayfish. Prawn and crayfish are crustaceans. Though they belong to the same family, prawn and crayfish differ in many ways. When comparing their physique, crayfish can be easily distinguished from prawns. Crayfish are bigger than prawns.
Alternative names [edit | edit source] Redclaw Crayfish, Blue Lobster, Australian Crayfish Origin [edit | edit source] This species is native to freshwater creeks and water bodies in tropical Queensland, the Northern Territory and south-eastern Papua New Guinea.
Callinectes sapidus (from the Greek calli-= "beautiful", nectes = "swimmer", and Latin sapidus = "savory"), the blue crab, Atlantic blue crab, or regionally as the Chesapeake blue crab, is a species of crab native to the waters of the western Atlantic Ocean and the Gulf of Mexico, and introduced internationally.
The Chinese mitten crab (Eriocheir sinensis) is a vector of the fatal crayfish plague pathogen (Aphanomyces astaci). Both species are listed among the world´s 100 worst invasive species. From its origin in China the Chinese mitten crab was introduced to Europe, presumably via ballast water from ships.
The common yabby (Cherax destructor) is an Australian freshwater crustacean in the Parastacidae family. It is listed as a vulnerable species of crayfish by the World Conservation Union (IUCN), though the validity of this listing is questionable ; wild yabby populations remain strong, and have expanded into new habitats created by reservoirs and farm dams.
The Dungeness crab is named after Dungeness, Washington, which is located approximately five miles 5 miles (8.0 km) north of Sequim and 15 miles (24 km) east of Port Angeles. Its typical range extends from Alaska's Aleutian Islands to Point Conception, near Santa Barbara, California, while it is occasionally found as far south as Magdalena Bay, Baja California Sur, Mexico.
There is a potential for ecological damage when crayfish are introduced into non-native bodies of water: e.g., crayfish plague in Europe, or the introduction of the common yabby (Cherax destructor) into drainages east of the Great Dividing Range in Australia.
The Florida stone crab (Menippe mercenaria) is a crab found in the western North Atlantic, from Connecticut to Belize, including Texas, the Gulf of Mexico, Cuba, The Bahamas, and the East Coast. The crab can also be found in and around the salt marshes of South Carolina and Georgia. It is widely caught for food.
Prawn vs Crayfish. Prawn and crayfish are crustaceans. Though they belong to the same family, prawn and crayfish differ in many ways. When comparing their physique, crayfish can be easily distinguished from prawns. Crayfish are bigger than prawns. Another noticeable difference is that a prawn is a saltwater crustacean, whereas crayfish is a freshwater crustacean.
Crayfish, also known as crawfish, crawdads, crawldads, freshwater lobsters, mountain lobsters, mudbugs or yabbies, are freshwater crustaceans resembling small lobsters, to which they are related; taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea.
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.
The Murray crayfish, Euastacus armatus, is a species of freshwater crayfish endemic to Australia that belongs to the family Parastacidae. The Murray crayfish has the largest geographic range of any of the Euastacus crayfish in Australia, being found in the Murray and Murrumbidgee Rivers as well as many of their tributaries.
Nephrops norvegicus, known variously as the Norway lobster, Dublin Bay prawn, langoustine (compare langostino) or scampi, is a slim, orange-pink lobster which grows up to 25 cm (10 in) long, and is "the most important commercial crustacean in Europe".
Procambarus fallax (also known as Georgia crawfish) is a species of crayfish in the genus Procambarus. It lives in tributaries of the Satilla River in Georgia and Florida. A parthenogenetic form of this species is known by the German name Marmorkrebs, or by the informal scientific name Procambarus fallax f.
The pill bug goes by many names—roly-poly, woodlouse, armadillo bug, potato bug. But whatever you call it, it's a fascinating creature, or actually 4,000 species of creature. The nocturnal crustaeans have seven pairs of legs, segmented sections like a lobster's tail, and prefer humid environments.
The rusty crayfish (Orconectes rusticus) is a large, aggressive species of freshwater crayfish which is native to the United States. Its range is rapidly expanding in North America, displacing native crayfishes in the process: it is known to have reached New England, Ontario, Illinois, Wisconsin, Michigan, Minnesota, Iowa, Missouri, Colorado, New Jersey, New York, Pennsylvania, Maryland, and even Manitoba.
The signal crayfish (Pacifastacus leniusculus) is a North American species of crayfish. It was introduced to Europe in the 1960s to supplement the Scandinavian Astacus astacus fisheries, which were being damaged by crayfish plague, but the imports turned out to be a carrier of that disease.
The Tasmanian giant freshwater crayfish (Astacopsis gouldi), also called Tasmanian giant freshwater lobster, is the largest freshwater invertebrate in the world. The species is only found in the rivers below 400 metres (1,300 ft) above sea level in northern Tasmania, an island-state of Australia.
In Singapore, the term crayfish typically refers to Thenus orientalis, a seawater crustacean from the slipper lobster family. True crayfish are not native to Singapore, but are commonly found as pets, or as an invasive species (Cherax quadricarinatus) in the many water catchment areas, and are alternatively known as freshwater lobsters.
Cymothoa exigua, or the tongue-eating louse, is a parasitic isopod of the family Cymothoidae. This parasite enters fish through the gills, and then attaches itself to the fish's tongue. The female attaches to the tongue and the male attaches on the gill arches beneath and behind the female.
