Augustus Addison Gould
Augustus Addison Gould (April 23, 1805 – September 15, 1866) was an American conchologist and malacologist. Biography Born in New Ipswich, New Hampshire, he was the son of music teacher Nathaniel Duren Gould (1781–1864) who was also noted for his penmanship. Physician He graduated from Harvard College in 1825, and took his degree of doctor of medicine in 1830.

Molluscs Of The Atlantic Ocean
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Cephalopods Of South America
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been identified. ...

Octopuses
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Lagos Region
Los Lagos Region ( es, Región de Los Lagos , ''Region of the Lakes'') is one of Chile's 16 regions, which are first order administrative divisions, and comprises four provinces: Chiloé, Llanquihue, Osorno and Palena. The region contains the country's second largest island, Chiloé, and the second largest lake, Llanquihue. Its capital is Puerto Montt; other important cities include Osorno, Castro, Ancud, and Puerto Varas. The mainland portion of Los Lagos Region south of Reloncaví Sound (Palena Province) is considered part of Patagonia. Historically, the Huilliche have called this territory between Bueno River and Reloncaví Sound Futahuillimapu, meaning "great land of the south". The region hosts Monte Verde, one of the oldest archaeological sites of the Americas. The largest indigenous group of the region are the Huilliche who lived in the area before the arrival of the Spanish. The Spanish crown settled Chiloé Archipelago in 1567 Hanisch, Walter.

Burdwood Bank
The Burdwood Bank, called Namuncurá in Argentina and other countries, is an undersea bank with a prominence of approximately 200 metres (110 fathoms), part of the Scotia Arc projecting some from Cape Horn in the South Atlantic Ocean and located some south of the Falkland Islands. Argentina claims economic rights over the whole of the bank, while the United Kingdom has designated about half of the bank as part of the Falklands Outer Economic Zone. The Burdwood Bank is one of the four morphological features defined by the 200 metre (110 fathom) isobath off the coast of the Argentine — the other three being the Patagonian Shelf (Argentine Coastal Shelf), Isla de los Estados and the Falkland Islands. It forms a barrier to the northward flow of the Antarctic Circumpolar Current. The bank itself (as defined by the 200 metre; 110 fathom isobath) is some from east to west and some from north to south. The channel to the west of the bank is about wide and deep while ...

Falkland Islands
The Falkland Islands (; es, Islas Malvinas, link=no ) is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and about from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British overseas territory, the Falklands have internal self-governance, but the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley on East Falkland. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements. Britain reasserted its rule in 1833, but Argentina maintains its claim to the islands. In April 1982, Argentine military forces invaded the islands. British a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beagle Channel
Beagle Channel (; Yahgan: ''Onašaga'') is a strait in the Tierra del Fuego Archipelago, on the extreme southern tip of South America between Chile and Argentina. The channel separates the larger main island of Isla Grande de Tierra del Fuego from various smaller islands including the islands of Picton, Lennox and Nueva; Navarino; Hoste; Londonderry; and Stewart. The channel's eastern area forms part of the border between Chile and Argentina and the western area is entirely within Chile. The Beagle Channel, the Straits of Magellan to the north, and the open-ocean Drake Passage to the south are the three navigable passages around South America between the Pacific and Atlantic Oceans. Most commercial shipping uses the open-ocean Drake Passage. The Beagle Channel is about long and wide at its narrowest point. It extends from Nueva Island in the east to Darwin Sound and Cook Bay in the Pacific Ocean in the west. Some from its western end, it divides into two branches, north ...

San Matías Gulf
The San Matias Gulf is an inlet of the Atlantic Ocean off the coast of Patagonia, Argentina. It is bordered by the Río Negro Province to the north and west, and the Valdes Peninsula of the Chubut Province to the south. It is "one of the largest gulfs in the Patagonia region". The gulf is surrounded by plateaus and depressions below sea level similar to the gulf itself but that are not flooded by the sea at present. The gulf was the subject of scientific investigation for its unusually large sand waves and their movement. The local fishing industry may be unsustainably harvesting the purple clam ('' Amiantis purpurata''), the Tehuelche scallop (''Aequipecten tehuelchus''), the blue mussel (''Mytilus edulis''), and the ribbed mussel (''Aulacomya atra''), as well as the Patagonian octopus (''Octopus tehuelchus''). The 2003 commercial squid harvest broke the previous record set in 2001 by more than double at . As of 2014, this gulf is the only location in the world where swimming wit ...
