Water shrew \Wa"ter shrew`\ (Zo["o]l.)
   Any one of several species of shrews having fringed feet and
   capable of swimming actively. The two common European species
   ({Crossopus fodiens}, and {C. ciliatus}) are the best known.
   The most common American water shrew, or marsh shrew
   ({Neosorex palustris}), is rarely seen, owing to its
   nocturnal habits.
