Habitat
This shrew primarily inhabits moist forests, grasslands, and riverbanks in Siberia and northern Asia. It prefers areas with dense undergrowth, leaf litter, and proximity to water sources for foraging. They are adaptable to various elevations up to 2,000 meters.
Diet
The Siberian large-toothed shrew feeds mainly on insects, earthworms, spiders, and other small invertebrates. It hunts actively by probing the soil and leaf litter, often consuming its body weight in food daily due to a high metabolic rate. Feeding occurs primarily at night, though they may forage during the day if needed.
Behavior
These shrews are solitary and territorial, defending small home ranges with scent markings. They are primarily nocturnal, spending the day in burrows or under vegetation, and exhibit high activity levels while foraging. They are aggressive when threatened and communicate through high-pitched vocalizations.
Conservation Status
The IUCN status of the Siberian large-toothed shrew is Least Concern, with a stable population trend. Major threats include habitat loss from deforestation and climate change impacts on their northern range.
