This mammal is actually not a rodent.  Its appearance is much like a mouse, but are a much closer relative to a mole.  The difference is that a shrew has spike-like teeth while a rodent has incisor front teeth for gnawing.  Shrews have a short tale with a long snout for a nose.  Their food source consists of insects, nuts and seeds. They are not as common as the other rodents, but they will enter structures, and nest in void areas where food sources are steady.
