Shrews are the smallest mammals, and among the most difficult to tell apart. The shrews can distinguish themselves from their cousins probably by using their keen noses. But mammalogists cannot rely on scent, so they typically examine subtle differences in size, color, and teeth to distinguish different species of shrews. The shrew art was done by Nancy Halliday working out of the Field Museum in Chicago.
