Arctoscopus Japonicus
The Japanese sandfish (''Arctoscopus japonicus''), also known as the sailfin sandfish , is a species of fish of the Percomorpha (perch-like) clade in the Order (biology), order Trachiniformes, being one of the two genera in the Family (biology), family Trichodontidae, the sandfishes. Known in Japan as , it is a commercially important fish especially for Akita Prefecture, Akita and Yamagata Prefecture, Yamagata prefectures. Its habitat occurs in sandy-mud Benthic fish, bottoms ranging from the Sea of Japan to the Okhotsk Sea. As a food source, the fish has mostly been sourced locally from the coastal region of the Sea of Japan, and has been designated the official prefectural fish of Akita Prefecture. The fish, which is scaleless, may be prepared whole as braised or grilled fish, and has a mucilaginous consistency. It is also dried to make stockfish; salted, dried, and made into ''himono''; and cured in miso as ''misozuke''. It is the main ingredient of the fish sauce called ''shot ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Sauce
Fish sauce is a liquid condiment made from fish or krill that have been coated in salt and fermented for up to two years. It is used as a staple seasoning in East Asian cuisine and Southeast Asian cuisine, particularly Myanmar, Cambodia, Laos, Philippines, Thailand, and Vietnam. Some garum-related fish sauces have been used in the West since the Roman times. Due to its ability to add a savory umami flavor to dishes, it has been embraced globally by chefs and home cooks. The umami flavor in fish sauce is due to its glutamate content. Fish sauce is used as a seasoning during or after cooking, and as a base in dipping sauces. Soy sauce is regarded by some in the West as a vegetarian alternative to fish sauce though they are very different in flavor. History Asia Sauces that included fermented fish parts with other ingredients such as meat and soy bean were recorded in China, 2300 years ago. During the Zhou dynasty of ancient China, fish fermented with soybeans and salt was u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uchiura Bay
The or is a bay southeast of the island of Hokkaido in northern Japan. It has also been known as Iburi Bay and Volcano Bay. History The shoreline of Uchiura Bay was first settled by the Jōmon people as early as 4000 BC. Trade settlements have been found along its shoreline, such as the Ōfune Site where the Jōmon people relied on the body of water for trade routes to other Jōmon settlements in northern Tōhoku. In modern history, the bay was charted during the late-eighteenth century voyage of Royal Navy Commander William Robert Broughton and the crew of during the eruption of nearby Mount Usu. Due to the eruptive activity, they labeled the bay as "Volcano Bay" in September 1796. Commander Broughton and his crew mingled extensively with the Ainu and Japanese living around the bay while they surveyed the bay's coastline. At a dinner they exchanged maps with the Japanese and conversed using Russian. Geography Uchiura Bay is a bay east of Oshima Peninsula that protrudes fro ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kamchatka Peninsula
The Kamchatka Peninsula (russian: полуостров Камчатка, Poluostrov Kamchatka, ) is a peninsula in the Russian Far East, with an area of about . The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the Kuril–Kamchatka Trench. The Kamchatka Peninsula, the Commander Islands, and the Karaginsky Island, constitute the Kamchatka Krai of the Russia, Russian Federation. The vast majority of the 322,079 inhabitants are ethnic Russians, although about 13,000 are Koryaks (2014). More than half of the population lives in Petropavlovsk-Kamchatsky (179,526 in 2010) and nearby Yelizovo (38,980).

Kurile Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Sea Fish
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1000–4000m deep) and abyssopelagic (4000–6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1000m deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
