The Himalayan water shrew (Chimarrogale himalayica) is a species of mammal in the family Soricidae. It is found in China, India, Japan, Laos, Myanmar, Taiwan, and Vietnam.
Shrews are small mole-like mammals classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, West Indies shrews, or marsupial shrews, which belong to different families or orders.
The red-toothed shrews of the subfamily Soricinae are one of three living subfamilies of shrews, along with Crocidurinae and Myosoricinae. In addition, the family contains the extinct subfamilies Limnoecinae, Crocidosoricinae, Allosoricinae and Heterosoricinae. These species are typically found in North America, northern South America, Europe and northern Asia. The enamel of the tips of their teeth is reddish due to iron pigment. The iron deposits serve to harden the enamel and are concentrated in those parts of the teeth most subject to wear.
Water shrew may refer to any of several species of semiaquatic red-toothed shrews:
The Malayan water shrew, also known as the hantu water shrew, is a red-toothed shrew recorded only from the Malaysian state of Selangor. It was listed as a critically endangered, but is now considered near threatened.
The Sumatran water shrew is a red-toothed shrew found only in the Padang highlands of western Sumatra, Indonesia. Its natural habitats are streams in montane forests. The species is only known from a holotype, which is damaged, and was previously listed as critically endangered by IUCN. It is believed to be severely threatened by habitat loss.
Aquatic and semiaquatic mammals are a diverse group of mammals that dwell partly or entirely in bodies of water. They include the various marine mammals who dwell in oceans, as well as various freshwater species, such as the European otter. They are not a taxon and are not unified by any distinct biological grouping, but rather their dependence on and integral relation to aquatic ecosystems. The level of dependence on aquatic life varies greatly among species. Among freshwater taxa, the Amazonian manatee and river dolphins are completely aquatic and fully dependent on aquatic ecosystems. Semiaquatic freshwater taxa include the Baikal seal, which feeds underwater but rests, molts, and breeds on land; and the capybara and hippopotamus which are able to venture in and out of water in search of food.
The Asiatic water shrews are the members of the genus Chimarrogale. They are mammals in the subfamily Soricinae of the family Soricidae. They are aquatic, with some species inhabiting streams. The genus contains the following species:
The Bornean water shrew is a species of mammal in the family Soricidae. It is endemic to Malaysia. Its natural habitat is rivers.
The Japanese water shrew, also called the flat-headed water shrew, is a species of mammal in the family Soricidae. It is endemic to Japanese Islands, Honshu and Kyushu. They are considered extinct in Shikoku.
The Chinese water shrew is a species of mammal in the family Soricidae. It is found in China and Myanmar.
Nectogalini is a tribe of Old World water shrews within the family Soricidae. As of late 2007, it consisted of six extant genera and 25 species, with some of the latter being further divided into subspecies.
A unicuspid is a tooth that has only one cusp.
Acasis viretata, the yellow-barred brindle, is a moth of the family Geometridae. The species was first described by Jacob Hübner in 1799. It is found from most of Europe and across the Palearctic to Korea. In northern India it is represented by Acacis viretata himalayica. It is also present in North America. It occurs in many different habitats, including deciduous and mixed forests, rocky slopes and valleys, as well as bushy meadows, bogs and taiga areas. In the Alps it can still be found at an altitude of 1700 meters
Agelaea is a genus of beetles in the family Carabidae, containing the following species:
Agelaea himalayica is a species of ground beetle from the Platyninae subfamily that is endemic to Nepal.
