The Townsend's mole (Scapanus townsendii ) is a fossorial mammal in the family Talpidae, and is the largest North American mole. It was named after the American naturalist John Kirk Townsend. The name was selected at the request of Thomas Nuttall as a patronym to honor Townsend's contribution.
It has velvety black fur, a pointed snout and a short, thick, a tail with barely any hair. It is about 21 cm (8.3 in) in length including a 4 cm (1.6 in) tail, and weighs about 138 grams (4.9 oz). Its front paws are broad and spade-shaped, specialized for digging; the rear paws are smaller. It has 44 teeth. Its ears are not visible and it has small eyes. It is similar in appearance to the smaller coast mole.
It is found in open lowland and wooded areas with moist soils along the Pacific coast from southwestern British Columbia to northwestern California. This animal's total range in Canada is estimated to be 20 km² (7.7 sq mi).
