WThe bathyal swimming crab, Bathynectes longispina, is a species of crab in the family Polybiidae.
WBathynomus giganteus is a species of aquatic crustacean, of the order Isopoda. It is a member of the giant isopods (Bathynomus), and it is related—albeit distantly—to shrimps and crabs.
WCallinectes bocourti is a species of swimming crab. Its native range extends from Jamaica and Belize south to Brazil, but it has been found as a nonindigenous species as far north as North Carolina. This crab has a light brown shell with red spots and markings on it, and red claws and legs. C. bocourti is edible and has been the subject of small-scale fishery.
WChaceon quinquedens, commonly known as the red deep-sea crab, but sold as Atlantic deep sea red crab, or simply Atlantic red crab or red crab is a crab that lives in the Atlantic Ocean off the East Coast of the United States and Canada, from North Carolina to Nova Scotia.
WThe "sea urchin crab" Echinoecus pentagonus is a species of crab in the family Pilumnidae found from the Red Sea and East Africa to French Polynesia and the Hawaiian Islands. This crab is a parasite that lives in the rectum of a sea urchin. In Hawaii, it chooses only Echinothrix calamaris, leaving few of these urchins unpopulated. Its curved and pointed carapace reaches only 0.5 inches (1.3 cm) in width.
WHaplophthalmus danicus, the terrestrial cave isopod, is a species of woodlouse in the family Trichoniscidae. It is found in Europe & Northern Asia, North America, Southern Asia, South America, and temperate Asia.
WMacrobrachium rosenbergii, also known as the giant river prawn or giant freshwater prawn, is a commercially important species of palaemonid freshwater prawn. It is found throughout the tropical and subtropical areas of the Indo-Pacific region, from India to Southeast Asia and Northern Australia. The giant freshwater prawn has also been introduced to parts of Africa, Thailand, China, Japan, New Zealand, the Americas and the Caribbean. It is one of the biggest freshwater prawns in the world and is widely cultivated in several countries for food. While M. rosenbergii is considered a freshwater species, the larval stage of the animal depends on brackish water. Once the individual shrimp has grown beyond the planktonic stage and becomes a juvenile, it will live entirely in freshwater.
WPenaeus esculentus is a species of prawn which is widely fished for consumption around Australia.
WPlatyxanthus crenulatus is a species of crab in the family Platyxanthidae. The species is found along the sublittoral zone of the western Atlantic in the waters of Brazil, Uruguay and Argentina, associated mostly with hard bottoms. Adults are robust and conspicuous crabs, with a smooth carapace, dorsally purple and white ventrally. Their claws have marked heterochely and right-handedness, traits associated with shell-breaking feeding habits. Due to its abundance, large size and diet, P. crenulatus presumably has an important ecological role as a predator in benthic communities.
WRochinia crassa, also known as the inflated spiny crab, is a species of crab in the family Epialtidae.
