Symphurus Thermophilus
''Symphurus thermophilus'' is a species of tonguefish notable for being the only flatfish known to be an obligate inhabitant of hydrothermal vents. It is known to inhabit several widely dispersed locations in the western Pacific Ocean and occurs in great numbers. These flatfish are distinguished by the prominent dark crossbands on their brown eyed side, black abdominal cavity membrane lining known as the peritoneum, and white blind side. They are tolerant of harsh conditions and are often found in close association with chemical element, elemental sulfur, including molten sulfur pools that exceed 180 °C in temperature. As they are not significantly different in appearance and feeding habits from other tonguefishes, they are thought to be relatively recent colonizers of vent ecosystems. Taxonomy These fish were first observed in nature in 1988, and were provisionally assigned to the species ''Symphurus orientalis'' before being recognized as a new species. The species name ...

Adult
An adult is an animal that has reached full growth. The biological definition of the word means an animal reaching sexual maturity and thus capable of reproduction. In the human context, the term ''adult'' has meanings associated with social and legal concepts. In contrast to a non-adult or " minor", a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and responsible. They may also be regarded as "majors". The typical age of attaining legal adulthood is 18 although definition may vary by legal rights, country, and psychological development. Human adulthood encompasses psychological adult development. Definitions of adulthood are often inconsistent and contradictory; a person may be biologically an adult, and have adult behavior, but still be treated as a child if they are under the legal age of majority. Conversely, one may legally be an adult but possess none of the maturity and responsibility that may de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microbial Mat
A microbial mat is a multi-layered sheet or biofilm of microbial colonies, composed of mainly bacteria and/or archaea. Microbial mats grow at interfaces between different types of material, mostly on submerged or moist surfaces, but a few survive in deserts. A few are found as endosymbionts of animals. Although only a few centimetres thick at most, microbial mats create a wide range of internal chemical environments, and hence generally consist of layers of microorganisms that can feed on or at least tolerate the dominant chemicals at their level and which are usually of closely related species. In moist conditions mats are usually held together by slimy substances secreted by the microorganisms. In many cases some of the bacteria form tangled webs of filaments which make the mat tougher. The best known physical forms are flat mats and stubby pillars called stromatolites, but there are also spherical forms. Microbial mats are the earliest form of life on Earth for which there ...

Nikkō Seamount
Nikkō Seamount () is a submarine volcano in the Volcano Islands region of Japan. It is the southernmost volcano of Japan. Geography The Nikkō caldera is a volcanic complex consisting of a caldera and 2 other cones that are the active parts of the volcano which last had an activity in 1979. It is south-southeast of Iwo Jima and north-northwest of Saipan. Marine life Nikkō is home to many underwater species, specifically 14 species which come from 12 families including the ''Symphurus thermophilus'', which are species that live in hydrothermal vent environments, which Nikkō has hydrothermal vents considering it is an active volcano. The seamount does also have endemic crustaceans, including the '' Paragiopagurus ventilatus''. Activity The volcano isn't the most active volcano, however the last activity recorded was in 1979. In July 12, 1979, a pale-green and wide patch of discolored water was observed over Nikkō Seamount. 2006 expedition In 2006, the NOAA Ocean Explorer prog ...

Seamount
A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (sea level), and thus is not an island, islet, or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface, such flat-top ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marianas Islands
The Mariana Islands ( ; ), also simply the Marianas, are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea, and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that the people who first settle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daikoku Seamount
Daikoku Seamount () is a submarine volcano located in the Northern Mariana Islands, in the western Pacific Ocean. It is situated on the Izu–Bonin–Mariana arc, Mariana volcanic arc. The seamount rises over meters from the seafloor, with its summit about below sea level. Since its discovery, the seamount has been studied by several expeditions, including expeditions made by NOAA, using various scientific tools, such as Sonar#Bathymetric mapping, sonar mapping and Remotely operated underwater vehicle, remotely operated vehicles (ROVs). Daikoku Seamount hosts an active hydrothermal vent system that hosts diverse communities of deep-sea organisms, including tube worms, crabs, and snails. At the summit of the seamount, a crater filled with molten liquid sulfur called "Sulfur Cauldron" exists, which was discovered in 2006. In 2014, it was discovered in an expedition that the seamount had erupted, forming 2 new craters on the summit. Geography The seamount is located around north ...

Okinawa Trough
The (also called , literally "China-Ryukyu Border Trough") is a seabed feature of the East China Sea. It is an active, initial back-arc rifting basin which has formed behind the Ryukyu arc-trench system in the West Pacific. It developed where the Philippine Sea Plate is subducting under the Eurasia Plate. Description It is a back-arc basin formed by extension within the continental lithosphere behind the far deeper Ryukyu Trench-arc system. The thickness of the crust in the northern Okinawa Trough is 30 km, thinning to 10 km in the southern Okinawa Trough. It has a large section more than deep and a maximum depth of . The Okinawa Trough still in an early stage of evolving from arc type to back-arc activity, and features volcanoes such as the Yonaguni Knoll IV.
