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 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. A mature adult may have a carapace width up to 25 centimetres and weigh up to 3 kilograms. C. pagurus is a nocturnal predator, targeting a range of molluscs and crustaceans. It is the subject of the largest crab fishery in Western Europe, centred on the coasts of the Ireland and Britain, with more than 60,000 tonnes caught annually.

Hypothalassia acerba is a large crab found in the muddy substrates of the deep seas off the southwestern Australian and New Zealand coasts. Australian distribution, which is correlated to depth and temperature, ranges from a latitude as far north as approximately 27° S on the west coast, southwards, then eastwards on the south coast to a longitude of at least 129° E. The species usually occurs in waters with temperatures of 13–19 °C (55–66 °F) and in depths ranging of 200–255 metres (656–837 ft) on the lower west coast and 90–200 m (300–660 ft) on the south coast. Body size is inversely related to depth of water. There are only two species in the genus Hypothalassia, and H. acerba is not the same champagne crab as the other Hypothalassia species, H. armata, which is found in Japanese waters.
Dyspanopeus sayi is a species of mud crab that is native to the Atlantic coast of North America. It has also become established outside its native range, living in Swansea Docks since 1960, the Mediterranean Sea since the 1970s, the North Sea since 2007 and the Black Sea since 2010. It can reach a carapace width of 20 mm (0.8 in), and has black tips to its unequal claws. It feeds on bivalves and barnacles, and is in turn eaten by predators including the Atlantic blue crab, Callinectes sapidus. Eggs are produced from spring to autumn, the offspring reach sexual maturity the following summer, and individuals can live for up to two years. The closest relative of D. sayi is D. texanus, which lives in the Gulf of Mexico; the two species differ in subtle features of the genitalia and the last pair of walking legs.

It has been found at depths of 1,515–2,643 metres (4,970–8,671 ft).
Davusia glabra, commonly called the shiny bait crab, Sowrie crab or Sourie crab is the sole species of crab in the genus Davusia. It lives around the low tide area on rocky ocean shores on the eastern coast of Australia, in crevices and rock pools and on rock platforms. Its distribution is stated differently in different sources; some have described the crab's habitat as from Queensland to as far south as the NSW-Victorian border, while others have stated it can be found as far south as Wilson's Promontory. Its carapace is grey to fawn-colored with very small green spots, resulting in Davusia glabra having a greenish appearance. The width of the carapace is around 30-40 mm across and is smooth without hair, slightly wider than long, with 3 distinct spines at each edge.
