Noroît Seamount
Noroit Seamount is a seamount in the Caribbean Sea, in the Anegada Passage. It is also spelled Noroît Seamount after the French survey and research vessel RV ''Le Noroît'' () which was operated by IFREMER. It is also known as Noroit Knoll. Several research projects are conducted in vicinity of Noroit Seamount. Geology The seamount is a (relatively young) inactive submarine volcano, located on the boundary between the North American Plate and the Caribbean Plate.Earthquake, Landslide, and Tsunami Hazards in the Northeastern Caribbean—Insights from a 2013 E/V Nautilus Expedition |
Anegada Passage
The Anegada Passage , also known as the Anegada Trough, is a strait in the Caribbean that separates the British Virgin Islands and the British ruled Sombrero Island of Anguilla, and connects the Caribbean and the Atlantic Ocean. It is 2300 m deep. Because the threshold depths are 1800 and 1600 m, Atlantic deep water from 1600 m level may flow into the deep areas in the Caribbean Sea. The Anegada Passage is a key shipping lane for the Panama Canal. Often called the "Oh-my-god-a Passage", it is considered a difficult passage for sailors because of the winds, waves, and swells. The Anegada Passage was the site of the 1867 Virgin Islands earthquake and subsequent tsunami. Geographic extent The multiple fault lines, ridges, and basins, including the Virgin Islands Basin, Anegada Gap, and Sombrero Basin, that form part of the general trough stretching from the southeastern Puerto Rican mainland in the Caribbean Sea to the northeastern British Virgin Island of Anegada in ...

Scleractinians
Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as across but in colonial species the polyps are usually only a few millimetres in diameter. These polyps reproduce asexually by budding, but remain attached to each other, forming a multi-polyp colony of clones with a common skeleton, which may be up to several metres in diameter or height according to species. The shape and appearance of each coral colony depends not only on the species, but also on its location, depth, the amount of water movement and other factors. Many shallow-water corals contain symbiont unicellular organis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexanchus Griseus
The bluntnose sixgill shark (''Hexanchus griseus''), often simply called the cow shark, is the largest Hexanchiformes, hexanchoid shark, growing to in length. It is found in tropical and temperate waters worldwide and its diet is widely varied by region. The bluntnose sixgill is a species of sixgill sharks, of genus ''Hexanchus'', a genus that also consists of two other species: the bigeye sixgill shark (Bigeyed sixgill shark, ''Hexanchus nakamurai'') and the Atlantic sixgill shark (Atlantic sixgill shark, ''Hexanchus vitulus''). Through their base pairs of mitochondrial genes COI and ND2, these three species of sixgills widely differ from one another. Taxonomy The first scientific description of the bluntnose sixgill shark was authored in 1788 by Pierre Joseph Bonnaterre. As a member of the family (biology), family Hexanchidae, it has more close relatives in the fossil record than living relatives. The related living species include the Squaliformes, dogfish, the Greenland sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bathypterois
''Bathypterois'' is a genus of deepsea tripod fishes. They are a diverse genus that belong to the greater family Ipnopidae and order Aulopiformes. They are distinguished by having two elongated pelvic fins and an elongated caudal fin, which allow them to move and stand on the ocean floor, much like a tripod, hence the common name. ''Bathypterois'' are distributed worldwide with some particular species of the genus having specialized environmental niches, such as lower dissolved oxygen concentrations. ''Bathypterois'' have a reduced eye size, highly specified extended fins, and a mouth adapted to filter feeding. They are filter feeders whose main food source is benthopelagic planktonic calanoid copepods, but some variation is seen with maturity in secondary food sources. Bathypterois use their three elongated fins for a wide range of motion from landing to standing on the ocean floor to catching prey, for which these fins serve as specialized perceptory organs.

World Register Of Deep-Sea Species
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...

Acanthonus Armatus
The bony-eared assfish (''Acanthonus armatus'') is a bathypelagic species of cusk-eel found in tropical and sub-tropical oceans at depths of from . It has been found as far north as Queen Charlotte Sound off British Columbia's coast. This species grows to a length of standard length. The larvae are similar in overall form to the related gargoyle cusk, but have elongated 3rd, 4th, and 5th pectoral-fin rays. The bony-eared assfish is by some sources believed to have the smallest brain-to-body weight ratio of any vertebrate. Like many other creatures that dwell in the depths of the sea, assfish are soft and flabby with a light skeleton. This is likely to have resulted from a lack of food and the high pressures which accompany living at such a depth, making it difficult to generate muscle and bone. Etymology The type specimen was an individual taken by the ''Challenger'' expedition (1872–1876) north of New Guinea at a depth of . It was described in 1878 by German ichthyologis ...

Sea Snails
Sea snails are slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example, species in the genus '' Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large and diverse group of animals. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide when they can move around in the air. These air-breathing species include false limpets in the family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squat Lobster
Squat lobsters are dorsoventrally flattened crustaceans with long tails held curled beneath the cephalothorax. They are found in the two superfamilies Galatheoidea and Chirostyloidea, which form part of the decapod infraorder Anomura, alongside groups including the hermit crabs and mole crabs. They are distributed worldwide in the oceans, and occur from near the surface to deep sea hydrothermal vents, with one species occupying caves above sea level. More than 900 species have been described, in around 60 genera. Some species form dense aggregations, either on the sea floor or in the water column, and a small number are commercially fished. Description The two main groups of squat lobsters share most features of their morphology. They resemble true lobsters in some ways, but are somewhat flattened dorsoventrally, and are typically smaller, ranging from 0.7 to 3.5 inches in length. Squat lobsters vary in postorbital carapace length (measured from the eye socket to the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brittle Stars
Brittle stars, serpent stars, or ophiuroids (; ; referring to the serpent-like arms of the brittle star) are echinoderms in the class Ophiuroidea, closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The ophiuroids generally have five long, slender, whip-like arms which may reach up to in length on the largest specimens. The Ophiuroidea contain two large clades, Ophiurida (brittle stars) and Euryalida (basket stars). Over 2,000 species of brittle stars live today. More than 1,200 of these species are found in deep waters, greater than 200 m deep. Range The ophiuroids diverged in the Early Ordovician. Ophiuroids can be found today in all of the major marine provinces, from the poles to the tropics. Basket stars are usually confined to the deeper parts of this range; Ophiuroids are known even from abyssal (>6,000 m) depths. However, brittle stars are also common members of reef communities, where they hide under rocks and even w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
