Short-tailed Shrew

 

 
Very small (4"-5") mammal, as in all shrews extremely energetic with a high metabolism.  Pointed head, distinct neck, and short tail give this shrew its field marks.  Ears are not visible, and eyes are very small, poorly developed.  Generally gray in color, darker on back.  Live about one to two years and are found throughout the eastern and midwestern U.S.  Shrews live in dark, damp, or wet areas such as flooded or weedy fields.  Shrews run over the surface and through burrows of other mammals in search of food, primarily at night (nocturnal).  They must eat at least half their body weight in food each day to survive.  They often attack and kill prey that are their own size, although most prey are insects and other invertebrates.
