Hairy-tailed mole

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.

Appearance

This animal has dark grey fur with lighter underparts, a pointed nose and a short, hairy tail.[6] 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).[6] Its front paws are broad and spade-shaped, specialized for digging.[7] It has 44 teeth. Its eyes are covered by fur and its ears are not external.[7] Its feet and snout are pinkish, but become white in older animals.[6] 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.[7] Moles rely very little on their eyesight and have very small optic nerves.[8] 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.[7]

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.[6] The hairy-tailed mole prefers deciduous and coniferous woods, oldfields, and roadsides.[6][2]

Behavior

The hairy-tailed mole is cathemeral.[6] 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.[6] 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.[6]

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.[9]

This animal is mainly solitary except during mating in early spring.[9] The female has a litter of 4 to 5 young in a deep burrow.[6][2] This mole may live 3 to 4 years.[9]

Diet

Hairy-tailed moles are insectivores and have been shown to starve if vegetable matter is the only food source available.[9] The hairy-tailed mole's diet is mostly grubs, earthworms, beetle larvae, slugs, and ants, particularly when other food sources are not available.[2][9]

gollark: PHP or AssemblyScript?
gollark: In that case, ALL are to use PHP?!
gollark: Really? Huh.
gollark: No, keeping Python in is required.
