Martialia Hyadesii
''Martialia hyadesii'' is a species of flying squid commonly known as the sevenstar flying squid. Distribution ''M. hyadesii'' occurs in epipelagic and mesopelagic waters of the Southern Ocean. Its range may be circumpolar with a Sub-Antarctic distribution. Ecology These large squid are known to prey upon deep-sea ridgeheads and other mesopelagic fish, and to be preyed upon in turn by king penguin The king penguin (''Aptenodytes patagonicus'') is the second largest species of penguin, smaller, but somewhat similar in appearance to the emperor penguin. There are two subspecies: ''A. p. patagonicus'' and ''A. p. halli''; ''patagonicus'' ...s and albatrosses.

Alphonse Trémeau De Rochebrune
Alphonse Amédée Trémeau de Rochebrune was a French botanist, malacologist and a zoologist. He was born on 18 September 1836 in Saint-Savin, and died on 23 April 1912 in Paris. Biography The son of a curator of the Museum of Angoulême, he became a military surgeon and reached the rank of adjutant in 1870. After obtaining his doctorate in 1874, he travelled to Saint-Louis in Senegal. In 1878, he joined the Muséum national d'histoire naturelle as an assistant in the Laboratory of Anthropology, and then replaced Victor Bertin (1849–1880), as assistant naturalist in the Laboratory of molluscs, worms and zoophytes, after Bertin's death. He held this post until his retirement in 1911. He addressed, in one hundred fifty publications, to a variety of subjects: from geology to paleontology, botany to malacology. These include his 1860 catalogue of wild flowering plants in the Department of Charente, co-written with Savatier Alexander. From 1882 to 1883, Rochebrune took part in a ...

Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

Molluscs Described In 1889
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. ...

Fauna Of The Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60th parallel south, 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific Ocean, Pacific, Atlantic Ocean, Atlantic, and Indian Ocean, Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albatross
Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains show they once occurred there and occasional vagrants are found. Albatrosses are among the largest of flying birds, and species of the genus ''Diomedea'' (great albatrosses) have the longest wingspans of any extant birds, reaching up to . The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species. Albatrosses are highly efficient in the air, using dynamic soaring and slope soaring to cover great distances with little exertion. They feed on squid, fish, and krill by either scavenging, surface seizing, or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several spe ...

King Penguin
The king penguin (''Aptenodytes patagonicus'') is the second largest species of penguin, smaller, but somewhat similar in appearance to the emperor penguin. There are two subspecies: ''A. p. patagonicus'' and ''A. p. halli''; ''patagonicus'' is found in the South Atlantic and ''halli'' in the South Indian Ocean (at the Kerguelen Islands, Crozet Island, Prince Edward Islands and Heard Island and McDonald Islands) and at Macquarie Island. King penguins mainly eat lanternfish, squid and krill. On foraging trips, king penguins repeatedly dive to over , and have been recorded at depths greater than . Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal and the orca. King penguins breed on the Subantarctic islands at the northern reaches of Antarctica, South Georgia, and other temperate islands of the region. King penguins also live on Macquarie Island in the Southern Ocean. At one time, these birds were exploited commercially for t ...

Ridgehead
Ridgeheads, also known as bigscales, are a family (Melamphaidae, from the Greek ''melanos'' lackand ''amphi'' y both sides of small, deep-sea stephanoberyciform fish. The family contains approximately 37 species in five genera; their distribution is worldwide, but ridgeheads are absent from the Arctic Ocean and Mediterranean Sea. Although the family is one of the most widespread and plentiful of deep-sea families, none of its members are of interest to commercial fishery. These fish are named for their large scales and pronounced cranial ridges, as well as for their typically dark brown to black coloration. Ridgeheads are the largest and most diverse family of their order. Description Typical of the Stephanoberyciformes, the melamphid body is robust, oblong, subcylindrical, and slightly compressed laterally. The head is large and scaleless, with its profile either bluntly rounded or with a sharp frontal angle; it is conspicuous for its prominent ridges, which are covered ...
