''Spisula sachalinensis'' (Japanese: , or , ; Uilta: ), the Sakhalin surf clam, is a species of edible saltwater clam in the family Mactridae, the surf clams or trough clams. It is commonly referred to as surf clam or Arctic surf clam, though the latter can also refer to '' Mactromeris polynyma''. The species is commercially exploited and widely used for sushi in Japan.孔 宁,李 琪,丛日浩,王庆库页岛厚蛤蜊的人工繁殖和胚胎发育 海洋科学,2011,(10):6-10 The species is found in Tomakomai, Hokkaido is a city and port in Iburi Subprefecture, Hokkaido, Japan.

Japanese Language
is spoken natively by about 128 million people, primarily by Japanese people and primarily in Japan, the only country where it is the national language. Japanese belongs to the Japonic or Japanese- Ryukyuan language family. There have been many attempts to group the Japonic languages with other families such as the Ainu, Austroasiatic, Koreanic, and the now-discredited Altaic, but none of these proposals has gained widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), there was a massive influx of Sino-Japanese vocabulary into the language, affecting the phonology of Early Middle Japanese. Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords. The basis of the standard dialect moved f ...

Uilta Language
Uilta ( oaa, ульта, also called Ulta, Uilta, Ujlta, or Orok) is a Tungusic language spoken in the Poronaysky and Nogliksky Administrative Divisions of Sakhalin Oblast, in the Russian Federation, by the Uilta people. The northern Uilta who live along the river of Tym’ and around the village of Val have reindeer herding as one of their traditional occupations. The southern Uilta live along the Polonay near city of Polonask. The two dialects come from northern and eastern groups, however they have very few differences. Classification Uilta is closely related to Nanai, and is classified within the southern branch of the Tungusic languages. Classifications which recognize an intermediate group between the northern and southern branch of Manchu-Tungus classify Uilta (and Nanai) as Central Tungusic. Within Central Tungusic, Glottolog groups Uilta with Ulch as "Ulchaic", and Ulchaic with Nanai as "Central-Western Tungusic" (also known as the "Nanai group"), while Oro ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clam
Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are ovoid or triangular; however, razor clams have an elongated parallel-sided shell, suggesting an old-fashioned ...

Mactridae
Mactridae, common name the trough shells or duck clams, is a family of saltwater clams, marine bivalve mollusks in the order Venerida. Description These clams have two short siphons, each with a horny sheath. The shell is shaped like a rounded-cornered equilateral triangle and there is a slight gape at the posterior. Each valve bears two cardinal teeth with four lateral teeth on the right valve and two on the left. The foot is white and wedge-shaped. They mostly inhabit the neritic zone. Ecology Trough shells burrow in sand or fine gravel and never in muddy substrates. Genera According to the World Register of Marine Species (2012), this family contains 37 genera: * '' Anatina'' Schumacher, 1817 * '' Austromactra'' Iredale, 1930 * '' Barymactra'' Cossmann in Cossmann & Peyrot, 1909 * '' Coelomactra'' Dall, 1895 * ''Crassula'' Marwick, 1948 * '' Cyclomactra'' Dall, 1895 * '' Darina'' Gray, 1853 * '' Diaphoromactra'' Iredale, 1930 * '' Eastonia'' Gray, 1853 * '' Harvella'' G ...

Sushi
is a Japanese cuisine, Japanese dish of prepared , usually with some sugar and salt, accompanied by a variety of , such as seafood, often raw, and vegetables. Styles of sushi and its presentation vary widely, but the one key ingredient is "sushi rice," also referred to as , or . The inventor of modern sushi is believed to be Hanaya Yohei, who invented nigiri-zushi, a type of sushi most known today, in which seafood is placed on hand-pressed vinegared rice, around 1824 in the Edo period (1603–1867). It was the fast food of the ''chōnin'' class in the Edo period. Sushi is traditionally made with white rice, medium-grain white rice, though it can be prepared with brown rice or Short grain rice, short-grain rice. It is very often prepared with seafood, such as Squid as food, squid, eel, Japanese amberjack, yellowtail, salmon, tuna or Crab stick, imitation crab meat. Many types of sushi are Vegetarian cuisine, vegetarian. It is often served with , wasabi, and soy sauce. Daiko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molluscs Described In 1862
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.
