In older long-tailed shrews, a loss of hair from the tail may be exhibited. The long-tailed shrew has a long, slender muzzle with long whiskers that range from 22 to 23 mm (0.87 to 0.91 in) long. [3] In the summer, the pelage color of the long-tailed shrew is slate gray with the ventral side of the body lighter than the dorsum. [4] [5]
Sorex ornatus sinuosus, known commonly as the Suisun shrew or Suisun ornate shrew, [3] is a subspecies of the ornate shrew that occurs in the tidal marshes of the northern shores of San Pablo and Suisun bays (northern arms of the San Francisco Bay, as far east as Grizzly Island and as far west as the mouth of Sonoma Creek in the vicinity of Tubbs Island).
The marsh shrew swims, making short dives in search of food; [1] its mobile snout, whiskers and lips are used to find and capture underwater prey. [14] Before eating, it returns to land.
