is a monotypic species found in the Oriental region of the world (Tate 1947). The Elegant Water Shrew is also found in the Himalayas and southeast Tibet, hence one of its other names, the Tibetan Water Shrew. (Corbet & Hill 1980)
As its common names would suggest,is found in or near water. It can be found in clean, mountain streams of China, Tibet, Nepal, etc. The shrew lives both in the water and in stream beds. (Parker 1990, 490)

The Elegant Water Shrew has soft, velvety fur. Its dorsal side is described as having slate-colored fur mixed in with long, white guard hairs (Tate, 1947). The ventral side of the shrew is similar in color to its dorsal side, but without the guard hairs (Parker 1990). The neutral fur coloring ofallows it to blend in easily with its background.
Its tail, which is moderately thick, is basically black except for the stiff-haired, white, lateral fringes that aid it in swimming and paddling. (Tate, 1947) These fringes merge together along the shrew's underside and give its tail a long pyramidal appearance (ITSES 1995, 10/8/01).
The streamlined shape of the shrew is enhanced by the strong reduction of its pinnae in its ears (Vaughan, Ryan, Czaplewski 2000, 116-7). In fact, the ears are so small that the outer ear conch can hardly be detected (Tate, 1947).
The only part of the shrew that is not gray is the fur around its mouth, which is cream-colored (Tate, 1947). The shrew also has a relatively long snout (Nowak 1995). The shrew's 28 teeth are adapted to feeding on fish.
On the soles of the shrew's feet are disk-shaped "adhesive" pads (Parker, 1990). These pads may help the shrew climb along wet rocks and may aid in the grasping of its prey (Nowak, 1995). The feet are also broad and webbed and also contain guard hairs to aid in swimming (Tate, 1947). These fringes of stiff, white hairs can be seen along the edges of the digits (Nowak 1995).
The size of theis large for a shrew. Its head and body length ranges from 90-128 mm and its tail length alone is about 89-110 mm (Parker, 1990). The Elegant Water Shrew is about the same size as the Musk Shrew, Suncus murinus (Tate, 1947).
Form and function go hand-in-hand in the Elegant Water Shrew. Its gray-and-white color along with iridescent fur allow the Elegant Water Shrew to blend in with its surroundings. The shape of the shrew makes it easier to dive for food. In addition to swimming and diving well, the shrew's adaptations also allow it to burrow into the banks of the streams it inhabits.

Communication and Perception
is an aquatic species that is well adapted to swimming and diving for its food. Its teeth are well adapted for eating small fish. Foods eaten by include insects and larvae, crustaceans, and small fish.

- terrestrial non-insect arthropods
Although there are descriptions ofthat date back to as early as 1870, not much is known about it.

- bilateral symmetry
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
an animal that mainly eats meat
uses smells or other chemicals to communicate
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.
