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 ...

The current site became home for the museum in 1946; the current building was construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Government Of Maryland
The government of Maryland is conducted according to the Maryland Constitution. The United States is a federation; consequently, the government of Maryland, like the other 49 state governments, has exclusive authority over matters that lie entirely within the state's borders, except as limited by the Constitution of the United States. Administrative influence in Maryland is divided among three branches of government: executive, legislative, and judicial. Unlike most other states, significant autonomy is granted to many of Maryland's counties. Most of the business of government is done in Annapolis, the state capital. However, some cabinet level and state officials have their offices in Baltimore. Almost all state and county elections are held in even-numbered years not divisible by four, in which the President of the United States is ''not'' elected—this, as in other states, is intended to divide state and federal politics. Executive branch The constitution establishes f ... [...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 Corpse decomposition, dead organisms that have died from causes other than predation or have been killed by other predators. While scavenging generally refers to carnivores feeding on carr ... [...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 four in ''C. sapidus''. Distribution ''Callinectes similis'' is found in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Capitol Dome
The United States Capitol features a dome situated above its rotunda. The dome is in height and in diameter. Designed by Thomas U. Walter, the fourth Architect of the Capitol, it was constructed between 1855 and 1866 at a cost of $1,047,291 (equivalent to $ in ). The '' Statue of Freedom'' tops the lantern on the dome, and the dome is centered over the origin on street maps of Washington, D.C. The dome is not stone, but rather cast iron carefully painted to appear to be made of the same stone as the capitol building below. It is actually two domes, one inside the other, and the total weight is . The dome's cast iron frame was supplied and constructed by the iron foundry Janes, Fowler, Kirtland & Co. in the Bronx, New York. The interior of the dome includes a detailed geometric and floral pattern of lightly colored plasterwork, with Brumidi's monumental ceiling fresco, '' The Apotheosis of Washington,'' appearing in the oculus at the top of the inner dome. First dome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mnemonic
A mnemonic device ( ), memory trick or memory device is any learning technique that aids information retention or retrieval in the human memory, often by associating the information with something that is easier to remember. It makes use of elaborative encoding, retrieval cues and imagery as specific tools to encode information in a way that allows for efficient storage and retrieval. It aids original information in becoming associated with something more accessible or meaningful—which in turn provides better retention of the information. Commonly encountered mnemonics are often used for lists and in auditory system, auditory form such as Acrostic, short poems, acronyms, initialisms or memorable phrases. They can also be used for other types of information and in visual or kinesthetic forms. Their use is based on the observation that the human mind more easily remembers spatial, personal, surprising, physical, sexual, humorous and otherwise "relatable" information rather tha ...

Sexual Dimorphism
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carapace
A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. In botany, a carapace refers to the hard outer cover of a seed which protects the inner embryo. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum. The carapace is calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portunidae
Portunidae is a family of crabs which contains the swimming crabs. Its members include well-known shoreline crabs such as the blue crab (''Callinectes sapidus'') and velvet crab ('' Necora puber''). Description Portunid crabs are characterised by the flattening of the fifth pair of legs into broad paddles, which are used for swimming. This ability, together with their strong, sharp claws, allows many species to be fast and aggressive predators. Taxonomy Swimming crabs reach their greatest species diversity in the Pacific and Indian Oceans. Portunidae consists of the following subfamilies and genera: ;Achelouinae ;Caphyrinae ;Carupinae ;Coelocarcininae ;Lupocyclinae ;Necronectinae ;Podophthalminae ;Portuninae ;Thalamitinae ;''incertae sedis or is a term used for a taxonomy (biology), taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washington Monument
The Washington Monument is an obelisk on the National Mall in Washington, D.C., built to commemorate George Washington, a Founding Fathers of the United States, Founding Father of the United States, victorious commander-in-chief of the Continental Army from 1775 to 1783 in the American Revolutionary War, and the first president of the United States from 1789 to 1797. Standing east of the Lincoln Memorial Reflecting Pool, Reflecting Pool and the Lincoln Memorial, the monument is made of Gneiss, bluestone gneiss for the foundation and of granite for the construction. The outside facing consists, due to the interrupted building process, of three different kinds of white marble: in the lower third, marble from Baltimore County, Maryland, followed by a narrow zone of marble from Sheffield, Berkshire County, Massachusetts, and, in the upper part, the so-called Cockeysville Marble. Both "Maryland Marbles" came from the "lost" Irish Quarry Town of "New Texas". It is both the world's tall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
