The American shrew mole (Neurotrichus gibbsii) is the smallest species of mole. It is the only living member of the genus Neurotrichus and the tribe Neurotrichini. It is also known as Gibb's shrew mole and least shrew mole. It is not closely related to the Asian shrew mole (Uropsilus in Urotrichini). Its shrew-like fur and typical mole head make the common name "shrew mole" fitting.
Habitat
It is found in damp, forested or bushy areas with deep, loose soils in the northwestern United States and southwestern British Columbia. In the most northern part of its habitat, it lives along streams or moist dense woods and in the most southern part of its habitat, it is found in swampy areas that are overgrown with vegetation such as sedges or shrubs.
Morphological features
Like shrews, it has a pelage with guard hairs and underfur. Its fur is dense and soft. The color ranges from dark gray to a sooty bluish-black. Its tail is about half the length of its head and body. Its tail is also covered with scales and scattered coarse hairs. It has a long, flattened snout, and a short but thick, bristled tail. It is the smallest of the American moles. Also, the three middle claws of the front paws are elongated and the eyes are also completely covered by skin.
