Habitat
This species inhabits moist, forested areas in the northeastern United States, particularly in deciduous and mixed woodlands near streams or wetlands. It prefers damp, shaded environments with plenty of leaf litter and undergrowth for cover. Geographic range is limited to regions like New England and the Appalachian Mountains.
Diet
The large-toothed shrew primarily eats insects such as beetles, ants, and earthworms, along with other small invertebrates like spiders and snails. It forages actively day and night, using its keen sense of smell to locate prey in leaf litter or soil. Feeding occurs frequently due to its high metabolic rate, often every few hours.
Behavior
Large-toothed shrews are solitary and territorial, marking their areas with scent and aggressively defending them from intruders. They are primarily nocturnal, spending the day in burrows or under logs and emerging at night to forage. These shrews exhibit high activity levels, constantly moving to maintain their body temperature, and they communicate through high-pitched vocalizations.
Conservation Status
The IUCN status of the large-toothed shrew is Least Concern, with stable populations in most of its range. Major threats include habitat loss from deforestation and urbanization, though it is not currently facing significant decline.
