''Parascalops''. The species epithet ''breweri'' refers to Thomas Mayo Brewer, an American naturalist.

Taxonomy

Despite inhabiting North America, studies indicate that it is not closely related to the two other North American scalopine moles ('' Scalopus'' and '' Scapanus''), but rather to the two Chinese scalopine moles ('' Scapanulus'' and '' Alpiscaptulus''). This indicates that the two Chinese moles likely descend from a migration from North America back into Eurasia, where the scalopine moles originated. Some studies have suggested placing ''Parascalops'', ''Scapanulus'', and ''Alpiscaptulus'' into a single subtribe Parascalopina.

Appearance

This animal has dark grey fur with lighter underparts, a pointed nose and a short, hairy tail. It is about in length, including a tail, and weighs about . Its front paws are broad and spade-shaped, specialized for digging. It has 44 teeth. Its eyes are covered by fur and its ears are not external. Its feet and snout are pinkish, but become white in older animals. Several adaptations to living primarily underground can be seen in the hairy-tailed mole. Its pelage is very dense and silky, and its feet are broad, flat, and heavy. Moles rely very little on their eyesight and have very small

mammal, it needs moist but well-drained soil so that it can dig easily. The hairy-tailed mole prefers deciduous and coniferous woods, oldfields, and roadsides.

Behavior

The hairy-tailed mole is cathemeral. Since it lives primarily underground in shallow tunnels it can forage throughout the day and will also forage on the ground's surface at night. The hairy-tailed mole is more active near the surface during warmer summer months and digs deeper underground in the cooler fall and winter months. This mole spends most of its time underground,

foraging Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavi ...
