Habitat
The Nicobar shrew inhabits tropical evergreen forests and dense undergrowth on the Nicobar Islands in the Indian Ocean. It prefers moist environments with leaf litter and is often found near streams or in areas with abundant vegetation cover. These shrews are endemic to this region, avoiding open or highly disturbed areas.
Diet
The Nicobar shrew primarily feeds on insects such as beetles, ants, and termites, as well as earthworms and other small invertebrates. It is a nocturnal forager, using its keen sense of smell to hunt actively in leaf litter and underbrush. Due to its high metabolism, it must eat frequently throughout the night.
Behavior
The Nicobar shrew is primarily nocturnal and solitary, spending its active hours foraging alone in the undergrowth. It exhibits territorial behavior, using scent marking to defend small home ranges, and is known for its rapid, darting movements when threatened. These shrews have a high metabolic rate, leading to constant activity and quick responses to environmental stimuli.
Conservation Status
The IUCN status of the Nicobar shrew is Vulnerable, with population trends declining due to habitat loss from deforestation and agriculture. Major threats include invasive species and human development on the Nicobar Islands.
