Japanese Sea Lion
The Japanese sea lion (''Zalophus japonicus'') (, ) was an aquatic mammal that became extinct in the 1970s. It was considered to be a subspecies of the related California sea lion (''Z. californianus'') until 2003. They inhabited the western North Pacific and its marginal seas including the Sea of Okhotsk and the Sea of Japan, especially around the coastal areas of the Japanese Archipelago and the Korean Peninsula. They generally bred on sandy beaches which were open and flat, but sometimes in rocky areas. They were hunted commercially in the 1900s, leading to their extinction. Taxonomy Prior to 2003, it was considered to be a subspecies of California sea lion as ''Zalophus californianus japonicus''. However, it was subsequently reclassified as a separate species. DNA analysis in 2007 estimated that the divergence point between the two sea lions took place around 2 mya (unit), million years ago (mya) in the early Pleistocene. Several taxidermied specimens can be found in Japan a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liancourt Rocks
The Liancourt Rocks, known in Korea as Dokdo () and in Japan as Takeshima (), are a group of islets in the Sea of Japan between the Korean Peninsula and the Japanese archipelago administered by South Korea. The Liancourt Rocks comprise two main islets and 35 smaller rocks; the total surface area of the islets is and the highest elevation of is on the West Islet. The Liancourt Rocks lie in rich fishing grounds that may contain large deposits of natural gas. The English name ''Liancourt Rocks'' is derived from , the name of a French whaling ship that came close to being wrecked on the rocks in 1849. While South Korea controls the islets, its sovereignty over them is contested by Japan. North Korea also claims the territory. South Korea classifies the islets as Dokdo- ri, Ulleung- eup, Ulleung County, North Gyeongsang Province, while Japan classifies the islands as part of Okinoshima, Oki District, Shimane Prefecture.

Yellow Sea
The Yellow Sea, also known as the North Sea, is a marginal sea of the Western Pacific Ocean located between mainland China and the Korean Peninsula, and can be considered the northwestern part of the East China Sea. Names It is one of four seas named after color terms (the others being the Black Sea, the Red Sea and the White Sea), and its name is descriptive of the golden-yellow color of the silt-ridden water discharged from major rivers. The innermost bay of northwestern Yellow Sea is called the Bohai Sea (previously Gulf of Zhili / Beizhili), into which flow some of the most important rivers of northern China, such as the Yellow River (through Shandong province and its capital Jinan), the Hai River (through Beijing and Tianjin) and the Liao River (through Liaoning province). The northeastern extension of the Yellow Sea is called the Korea Bay, into which flow the Yalu River, the Chongchon River and the Taedong River. Geography Extent The International Hydrographi ...

Spotted Seal
The spotted seal (''Phoca largha''), also known as the larga seal or largha seal, is a member of the family Phocidae, and is considered a "true seal". It inhabits ice floes and waters of the north Pacific Ocean and adjacent seas. It is primarily found along the continental shelf of the Beaufort, Chukchi, Bering and Okhotsk Seas and south to the northern Yellow Sea and it migrates south as far as northern Huanghai and the western Sea of Japan. It is also found in Alaska from the southeastern Bristol Bay to Demarcation Point during the ice-free seasons of summer and autumn when spotted seals mate and have pups. Smaller numbers are found in the Beaufort Sea. It is sometimes mistaken for the harbor seal to which it is closely related and spotted seals and harbor seals often mingle together in areas where their habitats overlap. The reduction in arctic ice floes due to global warming led to concerns that the spotted seal was threatened with extinction. Studies were conducte ...

Moneron Island
Moneron Island, (, , , Ainu: ) is a small island off Sakhalin Island. It is a part of the Russian Federation. Description Moneron has an area of about and a highest point of .

Steller's Sea Lion
The Steller sea lion (''Eumetopias jubatus''), also known as Steller's sea lion or the northern sea lion, is a large, near-threatened species of sea lion, predominantly found in the coastal marine habitats of the northeast Pacific Ocean and the Pacific Northwest regions of North America, from north-central California to Oregon, Washington and British Columbia to Alaska. Its range continues across the Northern Pacific and the Aleutian Islands, all the way to Kamchatka, Magadan Oblast, and the Sea of Okhotsk, south to Honshu's northern coastline. It is the sole member of the genus ''Eumetopias'', and the largest of the so-called eared seals (Otariidae). Among pinnipeds, only the walrus and the two species of elephant seal are bigger. The species is named for the naturalist and explorer Georg Wilhelm Steller, who first described them in 1741. Steller sea lions have attracted considerable attention in recent decades, both from scientists and the general public, due to significant ( ...
