Habitat
The Asian gray shrew inhabits forests, grasslands, and shrublands across Southeast Asia, including regions in India, China, and Indonesia. It prefers areas with dense vegetation and moisture, such as near streams or in undergrowth, which provide cover and prey. This species is adaptable to both lowland and montane environments up to 2,000 meters elevation.
Diet
The Asian gray shrew primarily eats insects like beetles, ants, and earthworms, as well as other small invertebrates such as spiders and centipedes. It hunts actively at night using its keen sense of smell and touch, consuming food frequently due to its high metabolic rate. Feeding occurs mainly on the ground or in leaf litter where prey is abundant.
Behavior
Asian gray shrews are solitary and territorial, defending small home ranges with scent markings. They are primarily nocturnal, emerging at night to forage and hunt while spending the day hidden in burrows or under debris. These shrews exhibit quick, erratic movements and vocalizations to communicate or ward off threats.
Conservation Status
The IUCN classifies the Asian gray shrew as Least Concern, with a stable population trend across its range. Major threats include habitat destruction from deforestation and agricultural expansion.
