The hairy-tailed mole (Parascalops breweri), also known as Brewer's mole, is a medium-sized North American mole. It is the only member of the genus Parascalops. [1] 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. [6]

Appearance

Illustration of the Hairy-tailed mole

This animal has dark grey fur with lighter underparts, a pointed nose and a short, hairy tail. [7] It is about 15 centimeters (5.9 in) in length, including a 3-centimeter-long (1.2 in) tail, and weighs about 55 grams (1.9 oz). [7] Its front paws are broad and spade-shaped, specialized for digging. [8] It has 44 teeth. Its eyes are covered by fur and its ears are not external. [8] Its feet and snout are pinkish, but become white in older animals. [7] 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. [8] Moles rely very little on their eyesight and have very small optic nerves. [9] To accommodate its lack of vision, the hairy-tailed mole has sensitive whiskers and hairs on the tip of its nose and feet to feel its surroundings. [8]

Habitat

It is found in forested and open areas with dry loose soils in eastern Canada and the northeastern United States. [2] Since it is a fossorial mammal, it needs moist but well-drained soil so that it can dig easily. [7] The hairy-tailed mole prefers deciduous and coniferous woods, oldfields, and roadsides. [7] [2]

Behavior

The hairy-tailed mole is cathemeral. [7] 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. [7] 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. [7]

This mole spends most of its time underground, foraging in shallow burrows for insects and their larvae and earthworms. [2] It emerges at night to feed. It is active year-round. Predators include owls, foxes and large snakes. [10]

This animal is mainly solitary except during mating in early spring. [10] The female has a litter of 4 to 5 young in a deep burrow. [7] [2] This mole may live 3 to 4 years. [10]

Diet

Hairy-tailed moles are insectivores and have been shown to starve if vegetable matter is the only food source available. [10] The hairy-tailed mole's diet is mostly grubs, earthworms, beetle larvae, slugs, and ants, particularly when other food sources are not available. [2] [10]

Moles are small mammals adapted to a subterranean lifestyle. They have cylindrical bodies, velvety fur, very small, inconspicuous eyes and ears, reduced hindlimbs, and short, powerful forelimbs with large paws adapted for digging.

<span class="mw-page-title-main">Talpidae</span> Family of small insectivorous mammals

The family Talpidae includes the moles who are small insectivorous mammals of the order Eulipotyphla. Talpids are all digging animals to various degrees: moles are completely subterranean animals; shrew moles and shrew-like moles somewhat less so; and desmans, while basically aquatic, excavate dry sleeping chambers; whilst the quite unique star-nosed mole is equally adept in the water and underground. Talpids are found across the Northern Hemisphere of Eurasia and North America, and range as far south as the montane regions of tropical Southeast Asia.

<span class="mw-page-title-main">North American least shrew</span> Species of mammal

The North American least shrew is one of the smallest mammals, growing to be only up to 3 inches long. It has a long pointed snout and a tail never more than twice the length of its hind foot. The dense fur coat is either grayish-brown or reddish-brown with a white belly. Its fur becomes lighter in the summer and darker in the winter. Although similar in appearance to several species of rodents, all shrews are members of the order Eulipotyphla and should not be mistaken for a member of the order Rodentia. The North American least shrew's eyes are small and its ears are completely concealed within its short fur, giving it very poor eyesight and hearing.

<i>Uropsilus</i> Genus of mammals

The shrew moles or shrew-like moles (Uropsilus) are shrew-like members of the mole family of mammals endemic to the forested, high-alpine region bordering China, Myanmar, and Vietnam. They possess a long snout, a long slender tail, external ears, and small forefeet unspecialized for burrowing. Although they are similar to shrews in size, external appearance, and, presumably, ecological habits, they are nevertheless talpids and considered true moles, as they share a full zygomatic arch with all other moles, while this arch is completely absent in shrews.

<span class="mw-page-title-main">American shrew mole</span> Species of mammal

The American shrew mole 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. The reason that it is called a "shrew mole" instead of being called either a "shrew" or a "mole" is because of its fur, which is a characteristic of shrews and its large head and heavy dentition, which is characteristic of moles.

The Scalopinae, or New World moles, are one of three subfamilies of the family Talpidae, which consists of moles and mole-like animals; the other two subfamilies being the Old World talpids and the Chinese shrew-like moles (Uropsilinae). The Scalopinae are the only Talpidae subfamily to consist entirely of undisputed moles and no mole-like close relatives such as shrew-moles or desmans.
