Desmans
Desmans are aquatic insectivores of the tribe Desmanini (also considered a subfamily, Desmaninae) in the mole (animal), mole family, Talpidae. This tribe consists of two living species found in Europe: the Russian desman (''Desmana moschata'') in European Russia, and the Pyrenean desman (''Galemys pyrenaicus'') in the northwest of the Iberian Peninsula and the Pyrenees. Both species are Endangered species, endangered, the Russian desman Critically Endangered, critically so. They have webbed paws and their front paws are not well-adapted for digging. Desmans were much more diverse and widespread during the Miocene, with two genera, ''Gaillardia (mole), Gaillardia'' and ''Magnatalpa'', being present in North America. Both living species are thought to have derived from the fossil genus ''Archaeodesmana.''

Talpidae
The family (biology), family Talpidae () includes the true Mole (animal), moles (as well as the shrew moles and desmans) who are small insectivore, insectivorous mammals of the order (biology), order Eulipotyphla. Talpids are all fossorial, digging animals to various degrees: moles are completely subterranean animals; shrew moles and shrew-like moles somewhat less so; and desmans, while basically aquatic, excavate dry sleeping chambers; whilst the quite unique star-nosed mole is equally adept in the water and underground. Talpids are found across the Northern Hemisphere of Eurasia and North America (although none are found in Ireland nor in the Americas south of northern Mexico), and range as far south as the Montane ecosystems, montane regions of tropical Southeast Asia. The first talpids evolved from shrew-like animals which adapted to digging late in the Eocene in Europe. ''Eotalpa, Eotalpa anglica'' is the oldest known mole, it was discovered in the Late Eocene deposits of Ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Desman
The Russian desman (''Desmana moschata''; ''vykhukhol'') is a small semiaquatic mammal that inhabits the Volga river, Volga, Don River, Russia, Don and Ural River basins in Russia. Some authorities, citing old Soviet sources, claim the animal can be found in Eastern Ukraine and Northern Kazakhstan, but, as of 2020, the accuracy of such claims is disputed. It constructs burrows into the banks of ponds and slow-moving streams, but prefers small, overgrown ponds with abundance of insects, crayfish and amphibians. The Russian desman often lives in small groups of two to five animals, that are usually not related, and appears to have a complex (but largely unstudied) communication and presocial, social system. Taxonomy The Russian desman is one of two surviving Monotypic taxon, species of the tribe ''Desmanini'', the other being the Pyrenean desman. Despite its outward similarity to muskrats (a rodent), the Russian desman is actually part of the mole (animal), mole family Talpidae ...

Aquatic Mammals
Aquatic mammals and semiaquatic mammals are a diverse group of mammals that dwell partly or entirely in body of water, 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. Mammal adaptation to an aquatic lifestyle vary considerably between species. River dolphins and manatees are both fully aquatic and therefore are completely tet ...

Mole (animal)
Moles are small, fossorial, subterranean mammals. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging. The word "mole" most commonly refers to many species in the family Talpidae (which are named after the Latin word for mole, ''talpa''). True moles are found in most parts of North America, Europe (except for Ireland) and Asia. Other mammals referred to as moles include the African Golden mole, golden moles and the Australian Marsupial mole, marsupial moles, which have a similar ecology and lifestyle to true moles but are unrelated. Moles may be viewed as pests to gardeners, but they provide positive contributions to soil, gardens, and ecosystems, including soil aeration, feeding on slugs and small creatures that eat plant roots, and providing prey for other wildlife. They eat earthworms and other small invertebrates in the soil. Terminology In Middle English, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desmana Nehringi
''Desmana'' is a genus of mole that contains a single living species, the Russian desman ''(Desmana moschata)''. A number of fossil species are known from throughout Eurasia. The oldest species is ''Desmana marci'' from the earliest Pliocene of Spain Spain, or the Kingdom of Spain, is a country in Southern Europe, Southern and Western Europe with territories in North Africa. Featuring the Punta de Tarifa, southernmost point of continental Europe, it is the largest country in Southern Eur .... It was probably derived from earlier moles of the genus '' Archaeodesmana''. ''D. marci'' likely gave rise to ''D. verestchagini'', who may have given rise to younger species such as the living desman.
