Habitat
This shrew inhabits the wet zone rainforests of Sri Lanka, particularly in areas with dense undergrowth, leaf litter, and moist soil. It prefers elevations from sea level up to about 1,000 meters, avoiding drier regions. Geographic distribution is limited to southwestern Sri Lanka, where it thrives in tropical evergreen forests.
Diet
The Sri Lankan rain forest shrew primarily feeds on insects such as beetles, ants, and termites, as well as earthworms and other small invertebrates. It forages actively at night, using its keen sense of smell to locate prey in leaf litter and soil. Feeding behavior is opportunistic, with the shrew consuming food frequently due to its high metabolic rate.
Behavior
This shrew is solitary and highly territorial, marking its area with scent and aggressively defending it from intruders. It is nocturnal, spending the day in burrows or under logs and emerging at night to forage. Notable behaviors include rapid movements and a high-pitched vocalization used for communication, with individuals covering extensive ground in search of food.
Conservation Status
The IUCN Red List classifies the Sri Lankan rain forest shrew as Least Concern, with a stable population trend. Major threats include habitat loss from deforestation and agriculture in Sri Lanka.
