Habitat
Saussure's shrew inhabits high-elevation forests, meadows, and moist mountainous regions in central Mexico, often near streams and in areas with dense undergrowth. It prefers cool, humid environments with plenty of cover from rocks and vegetation, typically at altitudes above 2,000 meters.
Diet
Saussure's shrew primarily eats insects such as beetles and ants, along with earthworms and other small invertebrates. It forages actively in leaf litter and soil, feeding frequently due to its high metabolism, and is known to hunt both day and night.
Behavior
Saussure's shrew is solitary and territorial, marking its area with scent and vocalizations to avoid encounters with others. It is primarily nocturnal, spending the day in burrows or under logs, and exhibits rapid, darting movements while foraging. This species has a high metabolic rate, requiring it to eat almost constantly to maintain energy.
Conservation Status
Saussure's shrew is classified as Least Concern by the IUCN, with a stable population trend; major threats include habitat loss from deforestation and climate change.
