Neomysis Americana
''Neomysis americana'' is an "extremely common" species of opossum shrimp along the Atlantic coast of North and South America. The species has a disjunct distribution, being present in an area extending from the Saint Lawrence River to Florida, and separately in parts of Argentina ( Blanca Bay, Anegada Bay and Samborombón Bay). There may be a further division within the North American populations between those north of Cape Henry, Virginia (including Georges Bank) and those from North Carolina southwards. ''N. americana'' is an important prey item for a number of fish species, including the Atlantic silverside, the bluefish and the windowpane flounder, ''Scophthalmus aquosus''. Adults typically have a carapace A carapace is a Dorsum (biology), 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.

He studied at the Sheffield Scientific School of Yale University, and received his Ph.B. in 1867. Yale University conferred upon him the honorary degree of M.A. in 1887. He stayed on at Yale, initially as an assistant, but from 1875 as the first professor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Henry
Cape Henry is a cape on the Atlantic shore of Virginia located in the northeast corner of Virginia Beach. It is the southern boundary of the entrance to the long estuary of the Chesapeake Bay. Across the mouth of the bay to the north is Cape Charles the opposite point of the Bay's gateway. Named for two sons of King James I of England in 1607, together Cape Henry and Cape Charles form the Virginia Capes. History Cape Henry was named on April 26, 1607 in honor of Henry Frederick, Prince of Wales, the elder of two sons of King James I of England to survive to the age of 18 and heir-apparent to the throne of the Kingdom of England (later united in 1707 with neighboring Scotland as the Kingdom of Great Britain), by an expedition of the London Company branch of the proprietary Virginia Company headed by Captain Christopher Newport. After an unusually long voyage of 144 days from England, it was their first landfall, an event which has come to be called "The First Landing". Soon aft ...

Crustaceans Of The Atlantic Ocean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their ...

Carapace
A carapace is a Dorsum (biology), 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. 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 (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, 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 Plate (animal anatomy), plate which carries the e ...

Bluefish
The bluefish (''Pomatomus saltatrix'') is the only extant species of the family Pomatomidae. It is a marine pelagic fish found around the world in temperate and subtropical waters, except for the northern Pacific Ocean. Bluefish are known as tailor in Australia and New Zealand, elf and shad in South Africa. It is a popular gamefish and food fish. The bluefish is a moderately proportioned fish, with a broad, forked tail. The spiny first dorsal fin is normally folded back in a groove, as are its pectoral fins. Coloration is a grayish blue-green dorsally, fading to white on the lower sides and belly. Its single row of teeth in each jaw is uniform in size, knife-edged, and sharp. Bluefish commonly range in size from seven-inch (18-cm) "snappers" to much larger, sometimes weighing as much as 40 lb (18 kg), though fish heavier than 20 lb (9 kg) are exceptional. Systematics The bluefish is the only extant species now included in the family Pomatomidae. At one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Silverside
The Atlantic silverside (''Menidia menidia''), also known as spearing in the northeastern United States, is a small species of fish from the West Atlantic, ranging from the Gulf of St. Lawrence in Canada to northeastern Florida in the USA. It is one of the most common fish in the Chesapeake Bay and in the Barnegat Bay. It is a common subject of scientific research because of its sensitivity to environmental changes. The fish is about long, mostly silver and white. It eats smaller (biotic) animals and plants – small crustaceans, algae, annelid worms, shrimp, zooplankton, copepods, amphipods, squid, and insects. The Atlantic silverside's predators are larger predatory fish – striped bass, blue fish, Atlantic mackerel – and many water birds, including egrets, terns, cormorants, and gulls. The abiotic factors the Atlantic silverside needs to survive varies for populations of fish based on their geographical location. A rule of thumb for the species includes an average ...

Georges Bank
Georges Bank (formerly known as St. Georges Bank) is a large elevated area of the sea floor between Cape Cod, Massachusetts (United States), and Cape Sable Island, Nova Scotia (Canada). It separates the Gulf of Maine from the Atlantic Ocean. The origin of its name is obscure. The 1610 Velasco map, prepared for King James I of England, used the name "S. Georges Banck", a common practice when the name of the English patron saint, St. George, was sprinkled around the English-colonized world. By the 1850s, it was known simply as Georges Bank. Physical environment Georges Bank is the most westward of the great Atlantic fishing banks. The now-submerged portions of the North American mainland are comprised in the continental shelf running from the Grand Banks of Newfoundland to Georges. Georges Bank was part of the North American mainland as recently as 12,000 years ago. Roughly oval in shape, Georges Bank measures about 149 miles (240 kilometres) in length by 75 miles (120 kilometr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
