Korean Red-backed Vole
The royal vole (''Myodes regulus''), also called the Korean red-backed vole, is a species of vole endemic to the Korean Peninsula. It lives underground in a burrow, emerging at night to feed on grasses, seeds and other vegetation. The International Union for Conservation of Nature has listed its conservation status as being of "least concern". Taxonomy British zoologist Oldfield Thomas first described the royal vole was in 1907 as ''Craseomys regulus'', the type locality being Mingyong in Korea, south east of Seoul. It was later transferred to the genus '' Myodes'', becoming ''Myodes regulus'', but many authorities believed it was a subspecies of ''Myodes rufocanus''. It has unrooted molar teeth, a characteristic shared by the very similar '' Myodes shanseius'' but not ''M. rufocanus'', and molecular analysis shows that it is a distinct species. Description This vole has a head-and-body length of about with a tail of . An adult royal vole weighs . The ears are large and are co ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Red-backed Vole
The grey red-backed vole or the grey-sided vole (''Myodes rufocanus'') is a species of vole. An adult grey red-backed vole weighs 20-50 grams. This species ranges across northern Eurasia, including northern China, the northern Korean Peninsula, and the islands of Sakhalin and Hokkaidō. It is larger and longer-legged than the northern red-backed vole (''Myodes rutilus''), which covers a similar range and it is also sympatric with the Norwegian lemming (''Lemmus lemmus''). Description The grey red-backed vole has a reddish-coloured back and grey sides. It has a head and body length of and a tail length of . It can be distinguished from the bank vole by its larger size and distinctive reddish back and from the northern red-backed vole by its larger size, longer legs and relatively longer tail. Unlike some other species of vole in the genus '' Myodes'', the molar teeth of adults are rooted in the jaws. Distribution and habitat The grey red-backed vole is native to northern ...

Mammals Of Korea
Approximately 100 species of mammal are known to inhabit, or to have recently inhabited, the Korean Peninsula and its surrounding waters. This includes a few species that were introduced in the 20th century; the coypu was introduced for farming in the 1990s, and the muskrat was introduced in the early 20th century into the Russian Far East, and was subsequently first recorded in Korea in the Tumen River basin in 1965. The Siberian tiger is the national animal of South Korea. The Siberian tiger and Amur leopard have most likely been extirpated from Korea, but are still included in standard lists of Korean mammals. Most Korean mammal species are found only in a small part of Korea. The large southeastern island of Jeju, and the rugged northeastern Paektu Mountain region, are particularly known for their distinctive mammal species. Several species, including the Dsinezumi shrew, are found only on Jeju, while many other species, such as the wild boar, are absent or extirpated f ...

Snake
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, altho ...
