The Arctic Shrew (Sorex arcticus), also known as the Blackback Shrew or Saddlebacked Shrew, is a medium-sized shrew found in Canada and the northern United States. Separate species status has been proposed for the Maritime Shrew (Sorex maritimensis) which is found in New Brunswick and Nova Scotia and had been considered to be a subspecies of the Arctic Shrew. The Tundra Shrew (Sorex tundrensis) was formerly considered to be a subspecies of the Arctic Shrew.

Famous quotes containing the word arctic:
“Nature confounds her summer distinctions at this season. The heavens seem to be nearer the earth. The elements are less reserved and distinct. Water turns to ice, rain to snow. The day is but a Scandinavian night. The winter is an arctic summer.”
—Henry David Thoreau (1817–1862)
