Treasures of Mt. Takao

The natural forest widely remain in Mt. Takao which is different from the man-made forests in nearby area. The south face is warm temperate forest with trees like oak trees and the north face is temperate forests with trees like Fagus crenata. About 30 kinds of animals including mammals such as flying squirrel and squirrel, reptile, amphibia and fish inhabits that prefers Mt. Takao's varieties of species of preys and forests. One way to enjoy exploring Mt. Takao is to find these animal's nests.

Urotrichus talpoides (Greater Japanese Shrew-mole)
Urotrichus talpoides (Greater Japanese Shrew-mole)Talpidae

Main region: Honshu, Shikoku, Kyushu, Awaji Island and Goto Islands. Found in forests and grasslands on hills and mountains rather than flatlands where most of species of moles are found. The Japanese name Himizu literally meaning does not live in the sun, however they live both on the ground and underground. Have longer tails than small Japanese moles. The fore legs are small and live in fallen leaves layers and have less ability to dig holes and live in litter layers or humis layers where it is not too deep underground and create tunnels. Become active at night and come out to the ground. Feed on earthworms, spiders and insects but sometimes fruits and seeds.

●Body Length about 8 to 11 cm
●Season  All year

Species of mammal

For the 2011 Japanese film, see Himizu (film).

The Japanese shrew mole or himizu (ヒミズ) (Urotrichus talpoides) is a species of mammal in the family Talpidae. It is endemic to Japan and is found on Honshu, Shikoku, Kyushu, Awaji Island, Shodo Island, Oki Islands, Tsushima Island, Goto Islands, Mishima Island (Yamaguchi Prefecture), and Awashima Island (Niigata Prefecture), but is absent from Hokkaido, which is north of Blakiston's Line. It is one of three Urotrichini and it is the only species in the genus Urotrichus. It is common between sea level and approximately 2,000 m.[2]

Heinrich Bürger, assistant of Philipp Franz von Siebold, collected specimens of Urotrichus talpoides near Dejima between 1824 and 1826, found lying dead in the fields, which were ultimately described by Temminck after shipping them to the Netherlands.[3]

ヒミズ Urotrichus talpoides Japanese shrew-mole

Greater shrew-mole

* Japanese name: Himizu
* Scientific name: Urotrichus talpoides
* Description: The greater shrew-mole belongs to the mole family but, befitting its name, it has features of both moles and shrews. It has short, thick, dark-brown to black fur that conceals its small eyes and ears, a pointy nose and forepaws that are only slightly broadened — more shrewlike than molelike. Body length is 9-10 cm, tail length 3-4 cm. Adults weigh between 14 and 20 grams. Although the fur is dense, it is not as lush and velvety as mole fur. It sometimes has a metallic sheen.
* Where to find them: The greater shrew-mole is found only in Japan, from Honshu to Kyushu, in open areas, woods and farmland. Unlike true moles, shrew-moles are agile and active aboveground. They are said to be less shy than moles, so are more easily spotted. Like shrews, shrew-moles make surface tunnels in leaves and grass. There are two species in Japan: the greater shrew-mole and the lesser shrew-mole, which lives in coniferous forests in the mountains. Both are common in their respective habitats. Greater shrew-moles forage aboveground as well as in their shallow tunnels and can even climb trees and bushes. In winter, shrew-moles are sometimes found dead in bird-nest boxes, having crawled inside in search of food and been unable to escape — the lonely, desperate fate of the one in the photo.
* Food: Spiders, insect larvae, small insects such as ants and anything that can’t put up a fight, such as worms, snails and slugs. Also, arthropods such as centipedes and sow bugs and even fungi and seeds.
* Special features: The shrew-mole’s densely haired tail is often thickened with fat. During the cold winter months, the animal can metabolize the fat in its tail to provide it with valuable energy. Around Tokyo, males are in good enough condition to start mating from mid-February to May, and females become pregnant in March and April. Baby shrew-moles are born (three or four to a litter) in April and May. Further south, mating starts in January and young are born as early as March. If food is plentiful and females are in good condition, there may be another round of reproduction, with more babies born from June to September. Gestation and lactation periods are short, just four weeks each.

Mole japanese shrew

Urotrichini

Tribe of mammals

Urotrichini is a tribe of the mole family, and consists of Japanese and American shrew-moles. They belong to the Old World moles and relatives branch of the mole family (Talpidae). There are only two species, each of which represents its own genus. The name "shrew-moles" refers to their morphological resemblance to shrews, while generally being thought of as "true moles". The species are the Japanese shrew mole,[1]True's shrew mole[2] and American shrew mole.[3][4][5][6][7][8]

In Japan, the word "Himizu" (ヒミズ) may refer to both to the Japanese shrew mole in particular and Urotrichini in general; when True's shrew mole is distinguished from the general Himizu forms, the feminine diminutive word "Hime" is added to refer to the smaller size of that species. Although they are common in Japan, their alpine habitats, small size, and secretive lifestyle makes them generally unknown except among some mountain people and researchers.

Morphology and ecological niche[edit]

Urotrichini paws are smaller and more downward- and backward-facing than the out-and-to-the-side orientation of the paws of classic moles, although not so much as in shrews. The limbs protrude slightly down and away from the body, as opposed to being invisibly retracted into the body with paws springing from just behind the head, as with moles. As such, Urotrichini are less well adapted than moles to forward burrowing, but better adapted to digging through the softer surface debris, leaf litter, and topsoils of alpine forest surfaces.

Nocturnality[edit]

Unlike true moles, Urotrichini are not equally active day and night. Himizu spend a large part of their days sleeping in specially excavated deep subsoil burrows.

Position within the family Talpidae[edit]

The Japanese shrewmole and True's shrewmole are more closely related to the American shrew mole than they are either Taiwanese and mainland Asian "shrew moles" or New World moles. These Urotrichini belong to members of the Old World moles subfamily, which also includes moles and desmans. The chiefly Chinese Uropsilinae shrew-like moles, despite previously having been called "shrew-moles" as well, are morphologically and genetically quite different, and comprise a sub-family of their own.

The taxonomy of this group has changed. Both Asiatic species had been thought of as one genus, Urotrichus. More recently, it was decided that a new genus, Dymecodon, be created within the Urotrichini to reflect significant morphological differences.

Distribution[edit]

The fluctuating borders between Urotrichini species in Japan have been the subject of study. Dymecodon pilirostris is found only at higher altitudes, possibly due to soil conditions. The larger Urotrichus talpoides dominates richer lowland areas, displacing D. pilirostris to the poorer soils on the steeper slopes of higher altitudes. Maps of these fluctuating boundaries show a sea of Japanese shrew mole territory dotted with islands of True's Shew mole on the steeper areas. This results in isolation of breeding populations of D. pilirostris and notable sub-speciation among the Himizu Hime which is not found among the standard Japanese shrew moles.[9][10]

On the cheek at any opportunity. He was not a womanizer either, and on the contrary, he behaved in a rather restrained manner in relations with women. And in glasses he generally seemed cute. The weather outside was terrible. It is damp.
