Nemertea
Nemertea is a phylum of animals also known as ribbon worms or proboscis worms, consisting of 1300 known species. Most ribbon worms are very slim, usually only a few millimeters wide, although a few have relatively short but wide bodies. Many have patterns of yellow, orange, red and green coloration. The foregut, stomach and intestine run a little below the midline of the body, the anus is at the tip of the tail, and the mouth is under the front. A little above the gut is the rhynchocoel, a cavity which mostly runs above the midline and ends a little short of the rear of the body. All species have a proboscis which lies in the rhynchocoel when inactive but everts to emerge just above the mouth to capture the animal's prey with venom. A highly extensible muscle in the back of the rhynchocoel pulls the proboscis in when an attack ends. A few species with stubby bodies filter feed and have suckers at the front and back ends, with which they attach to a host. The brain is a rin ...

Hiranai, Aomori
( ain, ピラナィ, piranay) is a town located in Aomori Prefecture, Japan and a part of the Aomori metropolitan area. , the town had an estimated population of 10,460 in 4,860 households, and a population density of 48 persons per km². It is the most heavily populated town in Higashitsugaru District. The total area of the town is . Etymology The name Hiranai is thought to have originated from the Ainu who originally inhabited the area. The Ainu words for and are said to be the original name of the area, due to its geography as a river valley in the interior of the mountainous Natsudomari Peninsula. However, the current Japanese pronunciation and meaning of the town's name, is descriptive of the valley, but is based on the flat area inside of the mountains or the bay that surrounds it. History During the Edo period, Hiranai was a village. On 17 September 1656, the village became part of Kuroishi Domain controlled by the Tsugaru clan. Up to the middle of the Edo period, t ...

Landforms Of Aomori Prefecture
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist Attractions In Aomori Prefecture
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 pa ...

Bays Of Japan
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a gulf, sea, sound, or bight. A cove is a small, circular bay with a narrow entrance. A fjord is an elongated bay formed by glacial action. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore with a broad, flat fronting terrace".Maurice Schwartz, ''Encyclopedia of Coastal Science'' (2006), p. 129.

Sannai-Maruyama Site
The is an archaeological site and museum located in the Maruyama and Yasuta neighborhoods to the southwest of central Aomori in Aomori Prefecture in northern Japan, containing the ruins of a very large Jōmon period settlement. The ruins of a settlement were discovered in 1992, when Aomori Prefecture started surveying the area for a planned baseball stadium. Archaeologists have used this site to further their understanding of the transition to sedentism and the life of the Jōmon people. Excavation has led to the discovery of storage pits, above ground storage and long houses. These findings demonstrate a change in the structure of the community, architecture, and organizational behaviors of these people. Because of the extensive information and importance, this site was designated as a Special National Historical Site of Japan in 2000., and a UNESCO World Heritage Site as part of the Jōmon Prehistoric Sites in Northern Japan collection in 2021. Today the public can visit the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jōmon People
is the generic name of several peoples who lived in the Japanese archipelago during the Jōmon period (). The Jōmon people may have consisted of multiple groups, which arrived and merged at different times in the Japanese archipelago, using multiple migration routes, rather than a single homogeneous people. Multiple studies on the Jōmon population analyzed the genetic contribution towards modern Japanese. Jōmon samples represented by a specimen obtained from the Funadomari archaeological site on Rebun Island and two specimens obtained from Honshu, show that mainstream Japanese people have inherited an average of 10% Jōmon period ancestry in their genome. The results of a study from 2021 inferred gene flow from the Jōmon period population to the modern Japanese across all migration models tested, with genetic contributions ranging from 8.9 to 11.5%. In the same study, the mean Jōmon component of the modern Japanese individual estimated using the admixture analysis was 9.31%. ...

Ascidiacea
Ascidiacea, commonly known as the ascidians, tunicates (in part), and sea squirts (in part), is a polyphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders. Ascidians are characterized by a tough outer "tunic" made of a polysaccharide. Ascidians are found all over the world, usually in shallow water with salinities over 2.5%. While members of the Thaliacea and Larvacea (Appendicularia) swim freely like plankton, sea squirts are sessile animals after their larval phase: they then remain firmly attached to their substratum, such as rocks and shells. There are 2,300 species of ascidians and three main types: solitary ascidians, social ascidians that form clumped communities by attaching at their bases, and compound ascidians that consist of many small individuals (each individual is called a zooid) forming colonies up to several meters in diameter. Sea squirts feed by taking in water through a tube, the oral siphon. The water enters the mouth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bioluminescent
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some Fungus, fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as Firefly, fireflies. In some animals, the light is bacteriogenic, produced by symbiosis, symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme Catalysis, catalyzes the Redox, oxidation of the luciferin. In some species, the luciferase requires other Cofactor (bio ...
