SHREW
,' a See also:term applied to the See also:species of the See also:family Soricidae of the mammalian See also:order insectivora (q.v.), but in the See also:British Isles to the See also:common and lesser shrews (Sorex araneus and S. minimus)
.
The common shrew, or, properly, shrew-See also:mouse, which in See also:England is by far the commoner of the two, is a small See also:animal
1 This word, whence comes the participial See also:adjective " shrewd," astute, originally meant malicious, and, as applied to a woman, still means a vexatious See also:scold
.
From their supposed venomous See also:character it was applied to the Soricidae
.
See also:young may be found in the nests; they are naked, See also:blind and toothless at See also:birth, but soon run about snapping at everything within reach
.
The alpine shrew (S. alpinus), restricted to the alpine region of Central See also:Europe, is slightly longer than the common shrew and differs in its longer tail, which exceeds the length of the See also:head and See also:body, in the See also:colour of the See also:fur, which is dark on both surfaces, and in the large See also:size of the upper antepenultimate premolar
.
The See also:water-shrew (Neomys fodiens), the third species inhabiting England, differs from the common shrew in being larger with a shorter and broader muzzle, smaller eyes and larger feet adapted for See also:swimming—the sides of the feet and toes being provided with See also:comb-like fringes of stiff hairs
.
The tail is longer than the body, and has a fringe of moderately See also:long regularly ranged hairs, which extend along the See also:middle of the under See also:surface from the end of the basal third to the extremity
.
The fur is long and dense, varying in colour in different individuals; the prevailing shades are dark, almost See also:black, See also: It is generally distributed throughout England, is less common in See also:Scotland and not recorded in See also:Ireland . The See also:geographical range of the common shrew is wide, extending eastwards through Europe and See also:Asia to Amurland . The lesser shrew extends through Europe and Asia to See also:Sakhalin See also:Island; and specimens of the water-shrew have been brought from different parts of Europe and Asia as far See also:east as the See also:Altai . In See also:Siberia the common shrew is abundant in the See also:snow-clad wastes about the Olenek See also:river within the See also:arctic circle . Other species of red-toothed shrews are restricted chiefly to See also:North See also:America, where they are found in greater variety than in the Old See also:World, though Neomys is not represented . Its See also:place is taken by Sorex palusiris east of the Rocky Mountains, and S. hydrodromus in Unalaska Island, which, like the water-shrew, have fringes of See also:hair on the feet, but the unfringed tail and dentition of the common shrew . Of the See also:American forms S. bendiri is the largest . Other red-toothed shrews belonging to the genus Blarina, distinguished from Sorex by the dentition and the shortness of the tail, are common in North America . All red-toothed shrews (except the aquatic forms) closely resemble one another,in habits, but the See also:short-tailed North American shrew supplements its insectivorous fare by feeding on See also:beech nuts . In destroying See also:numbers of slugs, insects and larvae, shrews aid the See also:farmer and merit See also:protection . Although their odour renders them safe from rapacious animals, they are destroyed in numbers by owls . (G . E . |
