Shrews are small, superficially mouse-like mammals of the family Soricidae. Although their external appearance is generally that of a long-nosed mouse, the shrews are not rodents and not closely related: the shrew family is part of the order Soricomorpha. Shrews have feet with five clawed toes, unlike rodents, which have four. Shrews are also not to be confused with treeshrews, which belong to their own unrelated order, the Scandentia.

There are 376 species of shrew in 26 genera, which are grouped into three living subfamilies: Crocidurinae (White-toothed shrews), Myosoricinae (African white-toothed shrews) and Soricinae (Red-toothed shrews). In addition, the family contains the extinct subfamilies Limnoecinae, Crocidosoricinae, Allosoricinae and Heterosoricinae (although Heterosoricinae is also commonly considered a separate family). Shrews are distributed almost worldwide: of the major temperate land masses, only New Guinea, Australia, and New Zealand do not have native shrews at all; South America has shrews only in the far-northern tropical part, like in Colombia. In terms of species diversity, the shrew family is the fourth most successful mammal family of all, being rivalled only by the muroid families Muridae and Cricetidae and the bat family Vespertilionidae. Genera see species list The White-toothed shrews or Crocidurinae are one of two subfamilies of the shrew family Soricidae. ...

In general, shrews are terrestrial creatures that forage for seeds, insects, nuts, worms and a variety of other foods in leaf litter and dense vegetation, but some specialise in climbing trees, living underground, or even hunting in water. All shrews are small, most no more than mouse size. The largest species is the House Shrew (Suncus murinus) of tropical Asia which is about 15 cm long and weighs around 100 grams; several are very small, notably the Etruscan Shrew (Suncus etruscus) which at about 3.5 cm and 2 grams is one of the smallest living mammals. Order : INSECTIVORA Family : Soricidae Species : Suncus murinus Head-Body Length : Up to 15 cm Tail Length : Up to 8 cm Weight : Up to 60 grams The Brown Musk Shrew, more commonly called the House Shrew, has become adapted to a quiet, nocturnal existence among agricultural areas, villages, towns and cities. ... Binomial name Suncus etruscus (Savi, 1822) The Etruscan Pygmy Shrew or the White-toothed Pygmy Shrew (Suncus etruscus) is the lightest known mammal by mass, weighting only 2 grams. ...

Shrews are unusual among mammals in a number of respects. Unlike most mammals, some species of shrew are venomous. Also, along with the bats and toothed whales, some species of shrew use echolocation. It has been suggested that Snake poison be merged into this article or section. ... Suborders Megachiroptera Microchiroptera See text for families. ... Families See text. ... There is evidence that a number of shrew species use echolocation. ... Echolocation, also called Biosonar, is the biological sonar used by several mammals such as bats, dolphins and whales. ...

Shrews have a high metabolic rate and so must feed almost constantly when not sleeping. Shrews are not able to hibernate. Overview of the citric acid cycle The citric acid cycle, one of the central metabolic pathways in aerobic organisms. ... Hibernation is a state of inactivity and metabolic depression in animals, characterized by lower body temperature, slower breathing, and lower metabolic rate, to conserve energy, especially during winter. ...

Unlike most other mammals, shrews are born with permanent teeth and do not have a zygomatic bone. The zygomatic bone (malar bone) is a paired bone of the human skull. ...

Shrews hold nearly 10% of their mass in their brain, a relatively high brain to body mass ratio.^[2] Brain to body mass ratio (also known as the Encephalization Quotient - EQ) is a rough estimate of the possible intelligence of an organism. ...
