Callinectes Sapidus
''Callinectes sapidus'' (from the Ancient Greek ,"beautiful" + , "swimmer", and Latin , "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. ''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 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 other 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 in the Atlantic coast. Whether this will have negative effects on the surrounding ecosys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callinectes Similis
''Callinectes similis'', sometimes called the lesser blue crab or dwarf crab, is a West Atlantic species of blue crab. It was described by Austin B. Williams in 1966. Description ''Callinectes similis'' is a good swimmer, and its last pereiopods are expanded to paddles with which it swims. Adult males may grow up to a width of , while females may reach . ''Callinectes similis'' is most closely related to '' Callinectes danae'', a species also found in the Gulf of Mexico, but whose range extends as far south as Rio Grande do Sul, and '' C. ornatus'', a species found from North Carolina to Rio Grande do Sul. ''C. similis'' is most easily separated from ''C. danae'' and ''C. ornatus'' by the form of the first and second pleopods in males. It can be told apart from the more distantly related '' C. sapidus'' by the number of teeth on the front edge of the carapace, there being six in ''C. similis'' and only two in ''C. sapidus''.

Callinectes Marginatus
''Callinectes marginatus'', known as the "sharptooth swimcrab" or "marbled swimcrab", is a species of swimming crab in the genus ''Callinectes''. Description Its carapace bears nine spines behind each eye, the last of which is around twice the length of the previous one, making the whole carapace around wide. Distribution and ecology Although the name ''Callinectes marginatus'' was used by Mary J. Rathbun and others to also cover animals now referred to the species '' C. larvatus'' and '' C. diacanthus'', ''C. marginatus'' is now used only for a species found from the Cape Verde Islands and Nouadhibou, Mauritania to Angola. ''C. marginatus'' appears to be entirely marine, unlike some of its congeners, although there are records from the estuaries of the Congo River and the Hwini River. The crabs dig holes around wide in mudflat Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments ...

Portunoidea
__NOTOC__ Portunoidea is a superfamily of crabs that includes the family Portunidae, the swimming crabs. Which other crab families are also placed here is a matter of some contention, and may be revised following molecular phylogenetic analyses. Description Their rather flat and smooth carapace is usually wider than long and of hexagonal, subhexagonal, rectangular, or transversely ovate shape. It is usually widest between the hindmost spines of the forward rim; there may be up to 9 pairs of these spines, with a few smaller ones right above the head, but they are missing altogether in some species. In some, the first maxilliped's endopod is lobed, forming the characteristic portunid lobe. The chelipeds are usually robust, and in some the last pereiopod pair has ovate dactyls. The sutures of the sternum between segments 4 to 8 are usually incomplete, and in the Portunidae, the eighth sternite is usually visible if seen from below and has a penial groove. In males, the abdomin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Callinectes Ornatus
''Callinectes ornatus'' is a species of swimming crab in the genus ''Callinectes''. It can be distinguished from the closely related Atlantic blue crab (''Callinectes sapidus'') by the presence of six frontal teeth on the carapace, compared with only four for ''C. sapidus''. ''C. ornatus'' is also smaller, at a maximum carapace width of only , compared to in ''C. sapidus'', and is therefore not commercially exploited. Their shells are light yellow-brown to red-brown in color. The lower tips of the claws are blue. The two spikes on each side of their shells are not as long as in blue crabs. They can be found in the western Atlantic Ocean, as well the Caribbean coastlines. Their diet consists of small crustaceans and small fish. They are also scavenger Scavengers are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators.
