Star nosed moles are one of the most distinctive types of mammal. Their noses are hairless and ringed by a unique ‘star’ of 22 pink, fleshy tentacles. The star has 11 appendages per side that vary in length from 1 to 4 mm. This species ranges from 175 to 205 mm in total length and weighs between 35 and 75 g. Like other moles it has a stout, roughly cylindrical body with heavily-built forelimbs, broad feet and large claws. Its hair is short, dense and coarser than that of other moles. The pelage is dark brown to black on the back and lighter brown underneath. During winter the tail swells 3 to 4 times its normal diameter.
