Habitat
This shrew inhabits tropical forests, grasslands, and scrublands in the Yucatan Peninsula of Mexico, preferring moist environments with leaf litter and undergrowth. It is often found at elevations up to 500 meters, avoiding open or arid areas.
Diet
The Yucatan small-eared shrew primarily eats insects such as beetles, ants, and spiders, as well as earthworms and other small invertebrates. It forages actively at night using its keen sense of smell, consuming food frequently due to its high metabolic rate.
Behavior
This shrew is solitary and territorial, marking its area with scent and aggressively defending it from intruders. It is primarily nocturnal, spending the day in burrows or under logs, and exhibits rapid, darting movements when foraging. Despite its small size, it has a bold and inquisitive nature.
Conservation Status
The IUCN lists the Yucatan small-eared shrew as Least Concern, with a stable population trend, though habitat loss from deforestation poses a potential threat.
