Lamellibrachia Satsuma
''Lamellibrachia satsuma'' (also known as Satsuma tubeworm or Satsumahaorimushi or ) was discovered near a hydrothermal vent in Kagoshima Bay, Kagoshima at the depth of only the shallowest depth record for a vestimentiferan. Its symbiotic sulfur oxidizer bacteria have been characterised as ε-Proteobacteria and γ-Proteobacteria. Subspecies have been later found associated with cold seeps at Hatsushima in Sagami Bay and at the Daini Tenryu Knoll in the Nankai Trough with specimens obtained at up to depth.

Hydrothermal Vent
A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kagoshima Bay
also known as Kinkō Bay, is a deep inlet of the East China Sea on the coast of Japan.''Merriam Webster's Geographical Dictionary, Third Edition'', p. 562. Kagoshima Bay is on the south coast of the island of Kyūshū. The port city of Kagoshima and its well-protected harbor lie on the bay's western coast, just opposite the island of Sakurajima. Geology The bay itself is partially volcanic in origin, with two massive submarine calderas shaping part of the bay's shoreline: The younger Aira Caldera in the northernmost part of the bay, and the older Ata Caldera at the mouth of the bay where it meets the East China Sea. Both calderas formed during the Pleistocene from highly explosive Ultra-Plinian volcanic eruptions, Aira approximately 22,000 years ago and Ata approximately 105,000 years ago. Though such enormous eruptions are extremely infrequent, both volcanoes have remained active with much smaller eruptions in historic times, with Sakurajima in the bay and the Kirishima ...

Kagoshima Prefecture
is a prefecture of Japan located on the island of Kyushu and the Ryukyu Islands. Kagoshima Prefecture has a population of 1,599,779 (1 January 2020) and has a geographic area of 9,187 km2 (3,547 sq mi). Kagoshima Prefecture borders Kumamoto Prefecture to the north and Miyazaki Prefecture to the northeast. Kagoshima is the capital and largest city of Kagoshima Prefecture, with other major cities including Kirishima, Kanoya, and Satsumasendai. Kagoshima Prefecture is located at the southernmost point of Kyūshū and includes the Satsunan Islands group of the Ryukyu Islands. Kagoshima Prefecture's mainland territory extends from the Ariake Sea to Shibushi Bay on the Pacific Ocean coast, and is characterized by two large peninsulas created by Kagoshima Bay. Kagoshima Prefecture formed the core of the Satsuma Domain, ruled from Kagoshima Castle, one of the most important Japanese domains of the Edo period and the Meiji Restoration.

Proteobacteria
Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as ''Escherichia'', ''Salmonella'', ''Vibrio'', ''Yersinia'', '' Legionella'', and many others.Slonczewski JL, Foster JW, Foster E. Microbiology: An Evolving Science 5th Ed. WW Norton & Company; 2020. Others are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation. Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". Because of the great diversity of forms found in this group, it was later informally named Proteobacteria, after Proteus, a Greek god of the sea capable of assuming many different shapes (not after the Proteobacteria genus ''Proteus''). In 2021 the Interna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Seep
A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. ''Cold'' does not mean that the temperature of the seepage is lower than that of the surrounding sea water. On the contrary, its temperature is often slightly higher. The "cold" is relative to the very warm (at least ) conditions of a hydrothermal vent. Cold seeps constitute a biome supporting several endemic species. Cold seeps develop unique topography over time, where reactions between methane and seawater create carbonate rock formations and reefs. These reactions may also be dependent on bacterial activity. Ikaite, a hydrous calcium carbonate, can be associated with oxidizing methane at cold seeps. Types Types of cold seeps can be distinguished according to the depth, as shallow cold seeps and deep cold seeps. Cold seeps can also be distinguished in detail, as follows: * oil/gas ...

Hatsushima
is an island in Sagami Bay, Japan. Administratively, it is part of the city of Atami, Shizuoka Prefecture, from which it can be reached by ferry. The island is approximately 10 kilometers from the ferry landing in downtown Atami. The island is inhabited, with the population mostly residing on the northern side of the island. As of 2018, the island had a population of 193 people in 114 households. Geology Hatsushima is located within the caldera forming Atami Bay, and was created by an uplift of the seafloor due to volcanic activity. This uplifting has occurred many times in the island's geological history, as evidenced by the many Terrace (geology), terraces formed by various uplifts. The elevation of the island is above sea level, and the island grew in height approximately two meters as a result of the 1923 Great Kantō earthquake. History Hatsushima has been inhabited since prehistoric times, and remains from the Jōmon period have been found in the island's interior. It i ...

Sagami Bay
lies south of Kanagawa Prefecture in Honshu, central Japan, contained within the scope of the Miura Peninsula, in Kanagawa, to the east, the Izu Peninsula, in Shizuoka Prefecture, to the west, and the Shōnan coastline to the north, while the island of Izu Ōshima marks the southern extent of the bay. It lies approximately southwest of the capital, Tokyo. Cities on the bay include Odawara, Chigasaki, Fujisawa, Hiratsuka, Itō, and Kamakura. History The center of the Great Kantō earthquake in 1923 was deep beneath Izu Ōshima Island in Sagami Bay. It devastated Tokyo, the port city of Yokohama, and the surrounding prefectures of Chiba, Kanagawa, and Shizuoka, and caused widespread damage throughout the Kantō region. The shallow nature of the seabed on the north of the bay, and the funnelling effect of tsunami and typhoon wave energy, contributed to certain parts of the Shonan coast having suffered considerable damage, including the destruction of the Kōtoku-in temple hou ...

Nankai Trough
The is a submarine trough located south of the Nankaidō region of Japan's island of Honshu, extending approximately offshore. The underlying fault, the ''Nankai megathrust,'' is the source of the devastating Nankai megathrust earthquakes, while the trough itself is potentially a major source of hydrocarbon fuel, in the form of methane clathrate. In plate tectonics, the Nankai Trough marks a subduction zone that is caused by subduction of the Philippine Sea Plate beneath Japan, part of the Eurasian plate (Kanda et al., 2004). This plate boundary would be an oceanic trench except for a high flux of sediments that fills the trench. Within the Nankai Trough there is a large amount of deformed trench sediments (Ike, 2004), making one of Earth's best examples of accretionary prism. Furthermore, seismic reflection studies have revealed the presence of basement highs that are interpreted as seamounts that are covered in sediments (Ike, 2004). The northern part of the trough is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sabellida
Sabellida is an order of annelid worms in the class Polychaeta. They are filter feeders with no buccal organ. The prostomium is fused with the peristomium and bears a ring of feathery feeding tentacles. They live in parchment-like tubes made of particles from their environment such as sand and shell fragments cemented together with mucus. Members of the suborder include the s (Sabellidae) and serpulid worms (Serpulidae). Among the species are the giant feather duster worm ('' |
Animals Described In 1997
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...
