Shrew
Shrews have long, narrow bodies; thin tails; and heads with long,
pointed snouts. The smallest shrew—as well as the smallest mammal in the
world—is Savi's pygmy shrew, which is about 2 1/2 inches (6.4 cm) long,
including a 1-inch (2.5-cm) tail, and weighs 1/14 ounce (2 g).Shrews are found around the world in temperate and tropical areas except
in Australia. There are more than 40 species in North America; one of
the most common is the short-tailed shrew. Most shrews are land animals,
but several species are aquatic. Aquatic shrews have stiff hairs on the
feet that trap air bubbles, allowing the animal to run on the surface
of the water. The Tibetan water shrew is the only shrew with webbed
feet. Shrews live mostly in moist areas such as swamps and bogs, and on
the moist, leaf-covered floors of deciduous forests.
