Cockspur Island
Cockspur Island is an island in the south channel of the Savannah River near Lazaretto Creek, northwest of Tybee Island, Georgia, United States. Most of the island is within the boundaries of Fort Pulaski National Monument. The island was so named on account of its bent shape. It was originally called Pepper Island and is also called Long Island. Historic buildings on the island include Fort Pulaski (built in 1847) and the Cockspur Island Lighthouse (built in 1837–39), designed by John S. Norris, the New York City architect. History The founder of Methodism, John Wesley landed at the island on February 6, 1736, and a monument marks the spot where Wesley conducted a service of thanksgiving. During the American Civil War, the Battle of Fort Pulaski was fought on the island, in which the United States Army captured the fort from the Confederate States Army on April 11, 1862. Confederate soldiers were imprisoned in the fort. During the Spanish–American War, a coastal artill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edible Bivalves
An edible item is any item that is safe for humans to eat. "Edible" is differentiated from "eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some mushrooms, insects, seaweed, and so forth – are referred to as edible. Processed items that normally are not ingested but are specially manufactured to be so, like edible underwear or edible packaging, are also labeled as edible. Edible items in nature It is estimated that approximately half of about 400,000 plant species on earth are edible, yet ''Homo sapiens'' consume only about 200 plant species, because these are the simplest to domesticate. Edible plants found in nature include certain types of mushrooms, flowers, seeds, berries, seaweed, and cacti. Being able to identify the versions of these plants that are safe to eat is an important survival skill. Many animals are also edible, including domesticated livestock as well as wild insect ...

Bivalve Genera
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances. The shell of a bivalve is composed of calcium ...

Magallana Gigas
The Pacific oyster, Japanese oyster, or Miyagi oyster (''Magallana gigas''), is an oyster native to the Pacific coast of Asia. It has become an introduced species in North America, Australia, Europe, and New Zealand. Etymology The genus ''Magallana'' is named for the Portuguese explorer Ferdinand Magellan and its specific epithet ''gígās'' is from the Greek for "giant". It was previously placed in the genus ''Crassostrea''; from the Latin ''crass'' meaning "thick", ''ostrea'' meaning "oyster", and ''Crassostrea gigas'' is considered by part of the scientific community to be the proper denomination as an accepted alternative in WoRMS, Description The shell of ''M. gigas'' varies widely with the environment where it is attached. Its large, rounded, radial folds are often extremely rough and sharp. The two valves of the shell are slightly different in size and shape, the right valve being moderately concave. Shell colour is variable, usually pale white or off-white. Mature speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crassostrea Ingens
''Crassostrea ingens'' is a species of fossil oyster, a marine bivalve mollusk in the family Ostreidae, the oyster. This species lived during the Pliocene. Fossils have been found in New Zealand shallow-water limestone and shellbeds. Locations include the Wairarapa, Whanganui basin, Gisborne district, North Canterbury, and Hawke's Bay Hawke's Bay ( mi, Te Matau-a-Māui) is a local government region on the east coast of New Zealand's North Island.

Leo George Hertlein
Leo George Hertlein (1898 – 1972) was an American paleontologist and malacologist who studied the Recent and fossil mollusks of the eastern Pacific Ocean. Biography Hertlein was born on a farm in Pratt County, Kansas. After graduating high school in Wichita, Kansas, he moved to the West Coast and entered the University of Oregon as a geology major. After graduating with a B.A., Hertlein enrolled as a graduate student at Stanford University. He received his doctorate in 1929. His dissertation was on the Pliocene fossils of the San Diego, California area. In 1929, Hertlein was appointed assistant curator of the Department of Paleontology at the California Academy of Sciences. He rose to become the curator of Invertebrate Paleontology and elected a Fellow. In the 1930s, he traveled to the Galapagos Islands and the nearshore areas of Central America and Mexico. He published over 150 papers on Recent and fossil mollusks, echinoderms, and brachiopods from California, Oregon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
