Callinectes Sapidus
''Callinectes sapidus'' (from the Ancient Greek language, Ancient Greek ,"beautiful" + , "swimmer", and Latin , "savory"), the blue crab, Atlantic blue crab, or, regionally, 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. ''C. sapidus'' is of considerable culinary and economic importance in the United States, particularly in Louisiana, the Carolinas, the Chesapeake Bay, Delaware, and New Jersey. It is the Maryland List of U.S. state crustaceans, state crustacean and the state's largest commercial fishery. Due to overfishing and environmental pressures some of the fisheries have seen declining yields, especially in the Chesapeake Bay fishery. Unlike the other Climate change and fisheries, fisheries affected by climate change, blue crab is expected to do well; warming causes better breeding conditions, more survivable winters, and a greater range of habitable areas on the Atlan ...

Blue Crab 11
The Blue Crab 11, also called the Gloucester 11, is an American utility dinghy that can be rowed, used as a motorboat or as a sailing dinghy. It was designed by Harry R. Sindle and first built in 1971. The design is named for the family of crustaceans.Sherwood, Richard M.: ''A Field Guide to Sailboats of North America, Second Edition'', pages 8-9. Houghton Mifflin Company, 1994. Production The design was built by Lockley Newport Boats and Mobjack Manufacturing in the United States, but it is now out of production. Lockley Newport Boats was originally known as Newport Boats and later known as Gloucester Yachts. A total of 900 examples of then type were completed. Design The Blue Crab 11 is a recreational sailboat, built predominantly of fiberglass. It has a fractional sloop rig, with a loose-footed mainsail and aluminum spars, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a retractable daggerboard. It displaces . The boat has a draft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The species varies in colour from dark blue to brown or pale grey, and may grow to in carapace width and weigh over . Description The carapace of ''Cardisoma guanhumi'' can reach a width up to . As with many crab species, males possess dimorphic claws; the larger claw can become longer than the carapace's width. The eyes are stalked and their colour ranges from a deep blue to a pale grey. juvenile (organism), Juveniles generally have a brown carapace with orange coloured legs.

Paralithodes Platypus
''Paralithodes platypus'', the blue king crab, is a species of king crab from cold waters in the North Pacific Ocean and adjacent seas. They are generally smaller than red king crabs. Distribution The blue king crab is found in cold waters in the Bering Sea, extending slightly into adjacent parts of the Chukchi Sea, off the Kamchatka Peninsula and northeastern Hokkaido, and in the Sea of Okhotsk. In the Bering Sea, the species is less widespread compared to red king crabs. The main populations near Alaska are found near the Diomede Islands, Point Hope, St. Matthew Island, and the Pribilof Islands. Additionally, a second, separate population exists in the Norton Sound all the way to St. Lawrence Island. Blue king crabs have a more northerly distribution compared to red king crabs, which is due to the colder waters of the northern Bering Sea being suitable for blue king crabs to survive. Their limited distribution is hypothesized to have been caused by a retreat into deeper, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portunus Pelagicus
''Portunus pelagicus'', also known as the blue crab, blue swimmer crab, blue manna crab and flower crab is a species of large crab found in the Indo-Pacific, including off the coasts Indonesia, Malaysia, Cambodia, Thailand, the Philippines, and Vietnam; and in the intertidal estuaries around most of Australia and east to New Caledonia. Description The males are bright blue in color with white spots and with characteristically long chelipeds, while the females have a duller green/brown, with a more rounded carapace. The carapace can be up to wide. Behaviour They stay buried under sand or mud most of the time, particularly during the daytime and winter, which may explain their high tolerance to ammonium (NH4+) and ammonia (NH3). They come out to feed during high tide on various organisms such as bivalves, fish and, to a lesser extent, macroalgae. They are excellent swimmers, largely due to a pair of flattened legs that resemble paddles. However, in contrast to another portunid cr ...

Portunus Segnis
''Portunus segnis'', the African blue swimming crab, is a species of crustacean, a swimming crab belonging to the family Portunidae. While native to the western Indian Ocean, it is also invasive in the Mediterranean. It is thought to have come through the Suez Canal from the Red Sea but it may have been transported by ships. Taxonomy ''Portunus segnis'' was first formally described in 1775 as ''Cancer segnis'' by the Swedish-speaking Finnish explorer, orientalist, naturalist, and an apostle of Carl Linnaeus Peter Forsskål with the type locality given as “Mari Rubro”, the Red Sea. It has been classified within the subgenus ''Portunus'' by some authorities. Until a review of the genus ''Portunus'' in 2010 ''P. segnis'' was considered to be a junior synonym of ''Portunus pelagicus''. The specific name ''segnis'' means “slow”, “torpid”, “lazy”, “unenergetic”, “tardy” or “inactive”, and Forskål described it as proceeding slowly in water ("''tarde ...
