Jeju Volcanic Island And Lava Tubes
The Jeju Volcanic Island and Lava Tubes is a World Heritage Site in South Korea. It was inscribed as one of the UNESCO World Heritage Sites in 2007 because of the Geomunoreum Lava Tube System and the exhibition of diverse and accessible volcanic features which are considered to demonstrate a distinctive and valuable contribution to the understanding of global volcanism. Jeju, also known as Jejudo, is a volcanic island, 130 kilometers from the southern coast of the Korean Peninsula. The largest island and smallest province in South Korea, the island has a surface area of 1,846 square kilometers. Formations A central feature of Jeju is Hallasan, the tallest mountain in South Korea and a dormant volcano, which rises 1,950 meters above sea level. The main volcano includes 360 satellite volcanoes. Volcanic activity on Jeju began approximately in the Cretaceous and lasted until the early Tertiary period. The most recent eruptions are estimated to be about 5,000 years ago, which puts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seogwipo
Seogwipo () is the second-largest city on Jeju Island, settled on a rocky volcanic coastline in the southern part of Jeju Province, South Korea. In July 2006, Seogwipo's boundaries were expanded to include the entire southern half of Jeju island. A UNESCO World Heritage site and 2002 FIFA World Cup host, it had a population of 155,691 as of December 31, 2011. History Early history Hundreds of Seogwipo’s oldest archeological artifacts were found in Saengsugwe Cave near Cheonjiyeon Waterfall on the south coast of Jeju. After an extensive excavation by a team of experts from Jeju National Museum in November 2010, hundred of Stone Age artifacts were unearthed. Another ancient location in Seogwipo is the village of Hamo. Artifacts found there during a 2005 excavation include pieces of earthenware and shell mounds from the Neolithic Age. In the beginning, Seogwipo was a part of Tamna, an ancient kingdom of Jeju. The kingdom traded with other nations across the Korean peninsula ...

North Pacific Right Whale
The North Pacific right whale (''Eubalaena japonica'') is a very large, thickset baleen whale species that is extremely rare and endangered. The Northeast Pacific population, which summers in the southeastern Bering Sea and Gulf of Alaska, may have no more than 40 animals. A western population that summers near the Commander Islands, the coast of Kamchatka, along the Kuril Islands and in the Sea of Okhotsk is thought to number in the low hundreds. Before commercial whaling in the North Pacific (i.e. pre-1835) there were probably over 20,000 right whales in the region. The taking of right whales in commercial whaling has been prohibited by one or more international treaties since 1935. Nevertheless, between 1962 and 1968, illegal Soviet whaling killed at least 529 right whales in the Bering Sea and Gulf of Alaska as well as at least 132 right whales in the Sea of Okhotsk, plus an additional 104 North Pacific right whales from unspecified areas.

Gray Whale
The gray whale (''Eschrichtius robustus''), also known as the grey whale,Britannica Micro.: v. IV, p. 693. gray back whale, Pacific gray whale, Korean gray whale, or California gray whale, is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of , a weight of up to and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age. The common name of the whale comes from the gray patches and white mottling on its dark skin. Gray whales were once called devil fish because of their fighting behavior when hunted. The gray whale is the sole living species in the genus ''Eschrichtius''. It was formerly thought to be the sole living genus in the family Eschrichtiidae, but more recent evidence classifies members of that family in the family Balaenopteridae. This mammal is descended from filter-feeding whales that appeared during the Neogene. The gray whale is distributed in an eastern North Pacific (North ...

Whale
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. As an informal and colloquial grouping, they correspond to large members of the infraorder Cetacea, i.e. all cetaceans apart from dolphins and porpoises. Dolphins and porpoises may be considered whales from a formal, cladistic perspective. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest non-cetacean living relatives are the hippopotamuses, from which they and other cetaceans diverged about 54 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have had their last common ancestor around 34 million years ago. Mysticetes include four extant (living) families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), and Eschrichtiidae (the grey whale). Odontocetes include the Monodontidae (b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finless Porpoise
''Neophocaena'' is a genus of porpoise native to the Indian and Pacific oceans, as well as the freshwater habitats of the Yangtze River basin in China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's List of countries and dependencies by population, most populous country, with a Population of China, population exceeding 1.4 billion, slig .... They are commonly known as finless porpoises. Genetic studies indicate that ''Neophocaena'' is the most basal living member of the porpoise family. There are three species in this genus: Description The finless porpoises are the only porpoises to lack a true dorsal fin. Instead there is a low ridge covered in thick skin bearing several lines of tiny tubercles. In addition, the forehead is unusually steep compared with those of other porpoises. With fifteen to twenty-one teeth in each jaw, they also have, on average, fewer teeth than other porpoises, although there is some ...

Indo-Pacific Bottlenose Dolphin
The Indo-Pacific bottlenose dolphin (''Tursiops aduncus'') is a species of bottlenose dolphin. This dolphin grows to long, and weighs up to . It lives in the waters around India, northern Australia, South China, the Red Sea, and the eastern coast of Africa. Its back is dark grey and its belly is lighter grey or nearly white with grey spots. The Indo-Pacific bottlenose dolphin is generally smaller than the common bottlenose dolphin, has a proportionately longer rostrum, and has spots on its belly and lower sides. It also has more teeth than the common bottlenose dolphin — 23 to 29 teeth on each side of each jaw compared to 21 to 24 for the common bottlenose dolphin. Much of the old scientific data in the field combine data about the Indo-Pacific bottlenose dolphin and the common bottlenose dolphin into a single group, making it effectively useless in determining the structural differences between the two species. The IUCN lists the Indo-Pacific bottlenose dolphin as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leopard Cat
The leopard cat (''Prionailurus bengalensis'') is a small wild cat native to continental South, Southeast, and East Asia. Since 2002 it has been listed as Least Concern on the IUCN Red List as it is widely distributed although threatened by habitat loss and hunting in parts of its range. Historically, the leopard cat of continental Asia was considered the same species as the Sunda leopard cat. As of 2017, the latter is recognised as a distinct species, with the taxonomic name ''Prionailurus javanensis''. Leopard cat subspecies differ widely in fur colour, tail length, skull shape and size of carnassials. Archaeological evidence indicates that the leopard cat was the first cat species domesticated in Neolithic China about 5,000 years ago in Shaanxi and Henan Provinces. Characteristics A leopard cat is about the size of a domestic cat, but more slender, with longer legs and well-defined webs between its toes. Its small head is marked with two prominent dark stripes and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberian Roe Deer
The Siberian roe deer, eastern roe deer, or Asian roe (''Capreolus pygargus''), is a species of roe deer found in northeastern Asia. In addition to Siberia and Mongolia, it is found in Kazakhstan, the Tian Shan Mountains of Kyrgyzstan, eastern Tibet, the Korean Peninsula, and northern China. Its specific name ', literally "white-rumped", is shared by the pygarg, an antelope known in the antiquity. The name was chosen by the German biologist Peter Simon Pallas in the late 18th century. The roe deer has long antlers. Taxonomy The Siberian roe deer was once considered to be the same species as the European roe deer (''Capreolus capreolus''), but it is now considered to be separate. The two subspecies of Siberian roe deer are ''C. p. pygargus'' and ''C. p. tianshanicus'' (named for the Tian Shan mountains). Description The Siberian roe deer is a moderately sized metacarpalian deer, with a long neck and large ears. It is typically up to in body length and in weight, making it l ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians ( tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...

Amphibian
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...
