Hokkaido
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people. While geographers such as Mogami Tokunai and Mamiya Rinzō explored the isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otaru, Hokkaidō
is a city and port in Shiribeshi Subprefecture, Hokkaido, Japan, northwest of Sapporo. The city faces Ishikari Bay and the Sea of Japan, and has long served as the main port of the bay. With its many historical buildings, Otaru is a popular tourist destination. Because it is a 25-minute drive from Sapporo, it has recently grown as a bedroom community. As of July 31, 2019, the city has an estimated population of 115,333 and a population density of 474.37 persons per km2 (1,228.6 persons per sq. mi.). The total area is . Although it is the largest city in Shiribeshi Subprefecture, the subprefecture's capital is the more centrally located Kutchan. History The city was an Ainu habitation, and the name "Otaru" is recognised as being of Ainu origin, possibly meaning "River running through the sandy beach". The very small remaining part of the Temiya Cave contains carvings from the Zoku-Jōmon period of Ainu history, around A.D. 400. Mount Akaiwa (Northwest part of Otaru) is m ...

Neotaenioglossa
The Neotaenioglossa is a taxonomic name for a large group of mostly sea snails. The name was originally created by Haller in 1882. Ponder and Warén (1988), and Marquet (1997), assigned this name to the superorder Caenogastropoda. ITIS considers the order Neotaenioglossa to be a synonym of Cerithioidea Férussac, 1819 . The taxonomy of the Gastropoda (Bouchet & Rocroi, 2005) no longer used this name. All families were assigned to the clades Littorinimorpha Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails ( marine species), but also including some freshwater snails ( aquatic species) and land snails (terrestrial species).Bouchet P. & Rocroi J.-P.

Finella
''Finella'' is a genus of sea snails, marine gastropod mollusks in the family Scaliolidae. This genus has been assigned in the course of time to different families by different authors: Rissoidae, Cerithiidae, Dialidae, Obtortionidae, Finellidae and Diastomatidae Morphological and anatomical studies by Winston Ponder in 1994 established that the genera ''Finella'' and ''Scaliola'' didn't belong in the above-mentioned families and he brought them in a new family Scaliolidae. This was supported in 1982 by Healy through the study of the ultrastructure on the spermatozoa. Description The species in this genus contain a small, elongated, conical shell without siphonal canal. The axial to spiral sculpture varies between weak and strong. Distribution The snails of this species are common to even abundant in shallow waters of the tropical Indo-West Pacific Ocean. Species Species within the genus ''Finella'' include: * ''Finella adamsi'' (Dall, 1889) * '' Finella barbarensis'' (Bartsc ...

Scyphozoa
The Scyphozoa are an exclusively marine class of the phylum Cnidaria, referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word ''skyphos'' (), denoting a kind of drinking cup and alluding to the cup shape of the organism. Scyphozoans have existed from the earliest Cambrian to the present. Biology Most species of Scyphozoa have two life-history phases, including the planktonic medusa or polyp form, which is most evident in the warm summer months, and an inconspicuous, but longer-lived, bottom-dwelling polyp, which seasonally gives rise to new medusae. Most of the large, often colorful, and conspicuous jellyfish found in coastal waters throughout the world are Scyphozoa. They typically range from in diameter, but the largest species, ''Cyanea capillata'' can reach across. Scyphomedusae are found throughout the world's oceans, from the surface to great depths; no Scyphozoa occur in freshwater (or on land). As medusae, they eat a ...

Smooth Lumpfish
The smooth lumpfish (''Aptocyclus ventricosus'') is a species of lumpfish native to the North Pacific where it is found at depths down to . This species grows to a length of TL. It is the only known member of its genus. Description The smooth lumpfish, or smooth lumpsucker, is a deep sea fish species with a body length of and body weight of on average. They look brownish gray with dark spots dorsally, muddy gray ventrally. They have naked skin without scales and tubercles. A smooth lumpfish has no dorsal spines or anal spines, eight to nine dorsal soft rays, and seven to nine anal soft rays. They have a rounded caudal fin and large and broadly based pectoral fins. Their pelvic fins are modified to form a clinging disc with a thickened margin on the ventral surface of the body. They have their first dorsal fins completed embedded under the skin. Habitat and Diet Smooth lumpfish are widely distributed throughout the North Pacific, especially in the Aleutian Basin. They inha ...

Lumpsucker
The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific. The family name ''Cyclopteridae'' derives from the Greek words ''κύκλος'' (kyklos), meaning "circle", and ''πτέρυξ'' (pteryx), meaning "wing" or "fin", in reference to the circle-shaped pectoral fins of most of the fish in this family. Description Lumpsuckers are named appropriately enough; their portly bodies are nearly spherical with generally drab coloration and lithic patterns. The "sucker" part refers to the fish's modified pelvic fins, which have evolved into adhesive discs (located ventrally, behind the pectoral fins); the fish use these discs to adhere to the substrate. Many species have bony, wart-like ''tubercles'' adorning the head and body; these are important taxonomic features of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great White Shark
The great white shark (''Carcharodon carcharias''), also known as the white shark, white pointer, or simply great white, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. It is notable for its size, with larger female individuals growing to in length and in weight at maturity. However, most are smaller; males measure , and females measure on average. According to a 2014 study, the lifespan of great white sharks is estimated to be as long as 70 years or more, well above previous estimates, making it one of the longest lived cartilaginous fishes currently known. According to the same study, male great white sharks take 26 years to reach sexual maturity, while the females take 33 years to be ready to produce offspring. Great white sharks can swim at speeds of 25 km/h (16 mph) for short bursts and to depths of . The great white shark is an apex predator, as it has no known natural predators other than, on v ...

Sea Anemone
Sea anemones are a group of predation, predatory marine invertebrates of the order (biology), order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and ''hydra (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Sargentii
''Prunus sargentii'', commonly known as Sargent's cherry or North Japanese hill cherry, is a species of cherry native to Japan, Korea, and Sakhalin (Russia). The tree was named for Charles Sprague Sargent. Description ''Prunus sargentii'' is a deciduous tree that grows tall and broad. New growth is a reddish or bronze color, changing to shiny dark green. The obovate leaves with serrated margins are in length and are arranged alternately. In fall, the leaves turn red, orange, or yellow. It grows single pink flowers on 1-in pedicels, which result in purple-black fruit in summer. The fruits are a favorite of birds, but because of their size (small, pea sized) and color, are considered inconspicuous to humans. Cultivation ''P. sargentii'' is a fast-growing ornamental tree requiring sun and well-drained soil. The tree can tolerate wind, but not air pollution; it is one of the hardiest cherries, and can be easily transplanted. This makes it suitable for use as a street tree. The ...
