Habitat
This species is endemic to Hainan Island in southern China, primarily inhabiting tropical forests, shrublands, and grasslands at elevations up to 1,000 meters. It prefers moist, dense undergrowth for cover and foraging, avoiding open or highly disturbed areas.
Diet
The Hainan Island shrew feeds mainly on insects such as beetles, ants, and earthworms, as well as other small invertebrates. It is an active forager, hunting primarily at night using its keen sense of smell and touch. Feeding occurs frequently throughout the night to support its high metabolic rate.
Behavior
The Hainan Island shrew is solitary and territorial, marking its area with scent and avoiding others of its kind except during mating. It is nocturnal, spending the day in burrows or under leaf litter, and exhibits rapid, darting movements while foraging. This species is highly active and vocal, producing high-pitched sounds for echolocation.
Conservation Status
The IUCN status is Critically Endangered due to habitat loss from deforestation and agriculture. Population trends indicate a continuing decline with major threats including fragmentation of forest habitats and potential invasive species.
