Callinectes sapidus, the blue crab, Atlantic blue crab, or, reigonally, the Maryland 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 Japanese spider crab is a species of marine crab and is the biggest one that lives in the waters around Japan. It has the largest known leg-span of any arthropod around 3.7 meters. The Japanese name for this species is taka-ashi-gani,, literally translating to “tall legs crab”. It goes through three main larval stages along with a prezoeal stage to grow to its great size.
The Dungeness crab makes up one of the most important seafood industries along the west coast of North America. Its typical range extends from Alaska's Aleutian Islands to Point Conception, near Santa Barbara, California. Dungeness typically grow 6-7 inches at their widest point and inhabit eelgrass beds and sandy bottoms. Its common name comes from the Dungeness Spit in the Strait of Juan de Fuca, Washington state, United States, which shelters a shallow bay inhabited by the crabs.
Calappa hepatica, the reef box crab, is a common benthic species of box crab of tropical and subtropical parts of the Indian and Pacific Oceans and the Red Sea.
Autotomy or 'self-amputation', is the behaviour whereby an animal sheds or discards one or more of its own appendages, usually as a self-defense mechanism to elude a predator's grasp or to distract the predator and thereby allow escape. Some animals have the ability to regenerate the lost body part later. Autotomy has multiple evolutionary origins and is thought to have evolved at least nine times independently in animals. The term was coined in 1883 by Leon Fredericq.
The bat ray is an eagle ray found in muddy or sandy sloughs, estuaries and bays, kelp beds and rocky-bottomed shoreline in the eastern Pacific Ocean, between the Oregon coast and the Gulf of California. It is also found in the area around the Galápagos Islands. The largest specimens can grow to a wingspan of 1.8 m and a mass of 91 kg (201 lb). They more typically range from 9.07–13.61 kg (20.0–30.0 lb). The size of the bat ray is dependent on many factors, such as habitat alterations, different oceanographic and environmental conditions. Bat rays have one to three venomous barbed spines at the base of its tail. Some bat rays are solitary while others form schools numbering in the thousands.
The Jonah crab is a marine brachyuran crab that inhabits waters along the east coast of North America from Newfoundland to Florida. Jonah crabs possess a rounded, rough-edged carapace with small light spots, and robust claws with dark brown-black tips. The maximum reported carapace width for males is 222 mm, while females rarely exceed 150 mm. It is the closest relative to the European brown crab in the Western Atlantic.
Paguristes cadenati, the red reef hermit crab or scarlet hermit crab, is a small species of hermit crab with a bright red body and yellow eyestalks that lives in the Caribbean Sea. The specific name honours the French ichthyologist Jean Cadenat (1908-1992), who collected the type specimen and sent it to the French carcinologist Jacques Forest, who described it as a new species.
Crab meat or crab marrow is the meat found within a crab, or more specifically in the leg of a crab. It is used in many cuisines around the world for its soft, delicate and sweet flavor. Crab meat is low in fat and provides approximately 340 kilojoules (82 kcal) of food energy per 85-gram (3 oz) serving. Brown crab, blue crabs, blue swimming crabs, and red swimming crabs are among the most commercially available species of crabmeat globally.
Menippe adina is a species of crab, sometimes called the Gulf stone crab or Western Gulf stone crab. It is very closely related to the Florida stone crab, Menippe mercenaria, of which it is sometimes considered to be a subspecies.
M. mercenaria may refer to:
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.
Libinia dubia, the longnose spider crab, is a species of crab in the family Epialtidae. It is found in shallow waters on the eastern coast of North America.
The thinstripe hermit crab, Clibanarius vittatus, is a species of hermit crab in the family Diogenidae. It is found in the Caribbean Sea, the Gulf of Mexico and the western Atlantic Ocean.
Loxorhynchus grandis, commonly known as the sheep crab or spider crab, is a species of crab in the family Epialtidae. It is the largest crab found on the California coast. The species was first described to science by William Stimpson in 1857. The type specimen was collected on the coast of California, near San Francisco. Fossils from the late Miocene epoch indicate that this species is at least 11.63 to 5.333 million years old.
Declawing of crabs is the process whereby one or both claws of a crab are manually detached before the return of the live crab to the water, as practiced in the fishing industry worldwide. Crabs commonly have the ability to regenerate lost limbs after a period of time, and thus declawing is viewed as a potentially more sustainable method of fishing. Due to the time it takes for a crab to regrow lost limbs, however, whether or not the practice represents truly sustainable fishing is still a point of scientific inquiry, and the ethics of declawing are also subject to debates over pain in crustaceans.
Alpheus heterochaelis, the bigclaw snapping shrimp, is a snapper or pistol shrimp in the family Alpheidae. It is found in the western Atlantic Ocean and the Gulf of Mexico.
Red Devil Vampire Crabs are decapod crustaceans part of Brachyura.
