Step 1
Identify the shrew, mole or vole by its size. Shrews are small and mouse-sized, while moles are larger, with bodies about 6½ to 7 inches long (not including the tail). Voles have compact, stocky bodies and are usually 5 to 7 inches long from the tip of the nose to the end of the tail.

Step 2
Study the fur. Shrews have dense fur that's a uniform color, not multicolored like mice. Voles usually have gray or brown fur, with dense under-fur and longer, thicker guard hairs.

Step 3
Look at the snout. Shrews have long, narrow skulls with distinct, elongated snouts. Moles have a hairless, pointed snout that extends nearly a half-inch beyond their mouths. Voles, on the other hand, don't have elongated snouts.

Step 4
Identify the shrew, mole or vole by its eyes. Moles have very small eyes, which are concealed by fur. Voles have larger eyes than moles and shrews, but the eyes are still small and partially hidden by fur. Shrews have small eyes that are not concealed by its fur.

Step 5
Study the feet. Shrews have five clawed toes on each foot. Voles have short legs and small, delicate feet and forefeet with only four toes, like other rodents. Moles have very large, broad forefeet with webbed toes, as well as hindfeet that are small and narrow with slender, sharp claws.

Step 6
Look at the tail. Shrews have long tails that can be nearly the same length as their bodies, while moles have 1¼-inch-long tails. Voles have stubby tails that are the shortest of the three.
