Tiny and often covered by fur
Most moles have tiny eyes that are often covered by fur to protect against debris underground. Their vision is poor and they rely on tactile cues rather than sight.
Which mole species is best known for living in coastal forests of the Pacific Northwest?
European mole
Star-nosed mole
Hairy-tailed mole
Coast mole
The coast mole (Scapanus orarius) inhabits coastal forests in the Pacific Northwest. It is adapted to the moist soils and temperate climate of that region.
Which of the following describes a common dietary habit of moles?
Grazing on grass and plant matter
Feeding primarily on earthworms and invertebrates
Predating on small mammals
Scavenging carrion
Moles are insectivores that feed mainly on earthworms and other soil invertebrates. Their diets rarely include plant material or larger prey.
How can you differentiate an eastern mole (Scalopus aquaticus) from a star-nosed mole by examining the snout?
Eastern mole has a flattened leaf-like snout
Eastern mole's snout has 22 tentacular rays
Eastern mole has a pointed snout without sensory tentacles
Eastern mole's snout is prehensile
The eastern mole has a pointed snout lacking the star-nosed mole's 22 tentacular rays. The star-nosed mole's snout is distinctively star-shaped, making identification straightforward.
Which morphological feature distinguishes the hairy-tailed mole (Parascalops breweri) from the eastern mole?
Webbed toes
Presence of dense hair on its tail
Brightly colored fur patches
Scaled tail
The hairy-tailed mole has a tail covered with dense hair, unlike the eastern mole whose tail is sparsely haired. This hairy tail is a key identification trait in the field.
What is the typical gestation period for most mole species?
About 60 days
About 90 days
About 15 days
About 30 days
Most mole species have a gestation period of approximately 30 days. This relatively short pregnancy aligns with their fast reproductive cycle in temperate climates.
Which habitat condition do moles generally avoid?
Forest undergrowth
Moist, loamy soils
Dry, compacted soils
Meadow edges
Moles prefer moist, loose soils that are easy to dig and support abundant invertebrates. Dry, compacted soils are difficult for them to tunnel through and rarely support their prey.
When comparing the fur of the star-nosed mole and the coast mole, which statement is accurate?
Coast mole has hairless body for thermal regulation
Coast mole fur is oily to repel water
Star-nosed mole has long guard hairs to sense vibrations
Star-nosed mole has water-repellent fur for wet tunnel conditions
The star-nosed mole occupies very wet and marshy soils and has water-repellent fur to maintain insulation and dryness. The coast mole's fur is less specialized for extreme moisture.
Which species exhibits the largest average home range among North American moles?
Hairy-tailed mole
Star-nosed mole
Coast mole
Eastern mole
The star-nosed mole often travels further each night to forage in wet habitats, giving it a larger home range than other North American moles. Others like the eastern mole have more localized tunnel systems.
How many functional digits are present on each forefoot of most mole species?
Four
Three
Five
Six
Most mole species have five functional digits on each forefoot, all equipped with strong claws for digging. This pentadactyl arrangement is typical across Talpidae.
Which bone structure is especially robust in moles for digging?
Scapula
Vertebrae
Femur
Humerus
The humerus in moles is greatly enlarged and reinforced to provide powerful leverage for digging. This adaptation is a hallmark of fossorial mammals.
In classifying mole specimens using dental formula, which tooth is elongated for grasping in moles?
Premolars
Molars
Canines
Incisors
Moles have elongated incisors that they use to grasp and process soil invertebrates. Their canines and molars are less specialized for this purpose.
Which sign differentiates coast mole activity from broad-footed mole?
Leaf litter nests
Open burrow entrances
Conical surface mounds
Surface ridges
The coast mole creates conical mounds on the surface when excavating soil, whereas the broad-footed mole produces winding surface ridges without pronounced mounds. These signs help distinguish their presence.
Molecular phylogenetic analysis places the star-nosed mole closest to which genus?
Talpa
Parascalops
Scapanus
Scalopus
Genetic studies show that the star-nosed mole (Condylura) is most closely related to the European genus Talpa. Other North American genera are more distantly related.
Which ecological adaptation allows moles to control tunnel microclimate?
Expanding tunnel volume
Sealing all entrances with fur
Soil plug formation to regulate humidity and temperature
Planting roots
Moles often plug old tunnel entrances with soil to reduce airflow, maintaining stable humidity and temperature inside. This behavior optimizes conditions for both comfort and prey preservation.
When comparing skeletal morphometry, a lower humeral torsion ratio indicates what in moles?
Arboreal adaptation
Gliding capacity
Greater digging specialization
Aquatic ability
A lower torsion ratio of the humerus is associated with the increased mechanical advantage needed for powerful digging. Other behaviors like arboreal or aquatic activity require different limb mechanics.
Which behavioral trait is most distinctive during mating season in star-nosed moles?
Surface courtship displays by males
Nocturnal vocalizations
Aggressive underground fights
Hibernation during mating
Male star-nosed moles often perform brief surface courtship displays to attract females. This behavior contrasts with many other mole species that mate underground.
In a comparative study, which trait correlates most strongly with soil hardness across mole species?
Skull length
Jaw size
Forelimb to body mass ratio
Ear size
Researchers found that species with a higher forelimb to body mass ratio can exert greater digging force in harder soils. Skull length and ear size showed no strong correlation.
