Bamboo
Bamboos are a diverse group of mostly evergreen perennial plant, perennial flowering plants making up the subfamily (biology), subfamily Bambusoideae of the grass family Poaceae.

A castle town is a settlement built adjacent to or surrounding a castle. Castle towns were common in Medieval Europe.

History Construction of the Castle The Satomi clan, virtually independent rulers of all of the Bōsō Peninsula during the Sengoku period, erected the original Ōtaki Castle in the early 1500s to guard the northern approaches to their domains, but fell into ruins by the end of the 16th century. This period of local hostilities, and the exploits of the Satomi clan, is richly described in the Bōsō Chiran-Ki. Edo Period In 1590, after Tokugawa Ieyasu was resettled in Edo, by order of Toyotomi Hideyoshi, he assigned Honda Tadakatsu to erect a new fortification to help contain the power of the Satomi in Tateyama Domain. The Satomi were destroyed by the Tokugawa shogunate in 1614, but the Honda continued to rule as ''daimyō'' of the 100,000 ''koku'' Ōtaki Domain for the following three generations. Cont ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 1,780 species divided into 166 valid genera. Cyprinids range from about in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless, or ''agastric'', fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used to identify spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribolodon
''Pseudaspius'', the redfin daces, is a genus of ray-finned fishes belonging to the family Leuciscidae, which includes the daces, chubs, true minnows and related fishes. The fishes in this genus arefound in marine and freshwater in eastern Asia, specifically the countries of Russia, Mongolia, China and Japan. Most species are diadromous into the Sea of Japan. Taxonomy ''Pseudaspius'' was first proposed as a monospecific genus in 1869 by the Polish zoologist Benedykt Dybowski with ''Cyprinus leptocephalus'' as its only species. ''C. leptocephalus'' was first formally described in 1776 by the German zoologist Peter Simon Pallas with its type locality given as Transbaikal. The genus ''Triblodon'' is now considered to be a synonym of ''Pseudaspius''. This genus is classified within the subfamily Pseudaspininae of the family Leuciscidae. Species These are the currently recognized species in this genus. * '' Pseudaspius brandtii'' ( Dybowski, 1872) (Pacific redfin) * '' Pseu ...

Oryzias Latipes
The Japanese rice fish (''Oryzias latipes''), also known as the medaka, is a member of genus ''Oryzias'' ( ricefish), the only genus in the subfamily Oryziinae. This small (up to about ) native of Japan is a denizen of rice paddies, marshes, ponds, slow-moving streams and tide pools. It is euryhaline, occurring in both brackish and freshwater. It became popular as an aquarium fish because of its hardiness and pleasant coloration: its coloration varies from creamy-white to yellowish in the wild to white, creamy-yellow, or orange in aquarium-bred individuals. Bright yellow, red or green transgenic populations, similar to GloFish, have also been developed, but are banned from sale in the EU. The medaka has been a popular pet since the 17th century in Japan. After fertilization, the female carries her eggs attached anterior to the anal fin for a period before depositing them on plants or similar things. Ecology Medaka live in small ponds, shallow rivers, and rice fields. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ayu Sweetfish
The ayu sweetfish (''Plecoglossus altivelis''), or sweetfish, is a species of fish. It is the only species in the genus ''Plecoglossus'' and family (biology), family Plecoglossidae. It is a relative of the Smelt (fish), smelts and other fish in the order Osmeriformes. Native to East Asia, it is distributed in the northwestern Pacific Ocean along the coast of Hokkaidō in Japan southward to the Korean Peninsula, China, Hong Kong and northern Vietnam. It is amphidromous, moving between coastal marine waters and freshwater lakes and rivers. A few landlocked populations also exist in lakes in Japan such as Lake Biwa, Biwa. Original wild populations in Taiwan became extinct in 1968 due to pollution and present extant populations were reintroduced from Japan in the 1990s. The name "sweetfish" was inspired by the sweetness of its flesh. In reference to its typical one-year lifespan, it is also written as ("year-fish").

Tokyo Bitterling
The Tokyo bitterling (''Pseudorhodeus tanago'') is a temperate freshwater ray-finned fish belonging to the family Acheilognathidae. This fish is endemic to the island of Honshu in Japan. The species was first described as ''Rhodeus tanago'' by Shigeho Tanaka in 1909. It is widely known as ''Tanakia tanago'', although a 2014 study suggests it is genetically distinct from other '' Tanakia'' species, and warrants placement of it in the monotypic genus ''Pseudorhodeus''. Distribution In the wild, this fish is found only on the Kantō Plain of Japan, an area near the capital city, Tokyo. The fish was formerly abundant in small streams, but its habitat has been overrun by people and pollution. Threats There is a real risk that it could become extinct in the wild. It also suffers from competition from the related but more aggressive rosy bitterling. Bitterlings lay their eggs in freshwater mussel shells. The Tokyo bitterling lays its eggs in only one type of mussel shell, limiting its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bank (geography)
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the Stream bed, bed of a river, creek, or stream. The bank consists of the sides of the channel (geography), channel, between which the streamflow, flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the Deposition (geology), deposits and landforms created by them. Bankfull discharge is a Discharge (hydrology), discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking current (stream), downstream; a well-known example of this being the southern Rive Gauche, left bank and the northern Rive Droite, right bank of the river Seine definin ...
