The Yucatan small-eared shrew has short gray fur and tiny eyes. It occurs in lowland areas around the Yucatan Peninsula and searches for small prey at night.
Its fur is short and gray, its eyes are tiny, and its small ears are hidden in the fur. The tail is short and lightly furred.
The Yucatan Small-eared Shrew inhabits lowland forest and dry scrub on the Yucatán Peninsula. It has tiny eyes and ears and a short tail.
On 4 May 2023, one was captured in a two-year-old oil-palm plantation near the Tabasco–Campeche border, México. Researchers investigating crop-damaging rodents had set 100 traps for two nights; the shrew appeared on the second night.
After checking its size and coloration, they photographed and released it; the photographs entered a university collection. Pastures surrounded the plantation, and the nearest forest patch was about 800 metres away. The authors suggested that the shrew might inhabit the plantation itself. This single encounter raised a question about its use of transformed land.
An extinction-risk assessment has not been added yet.
At the 2023 study site, much forest had become pasture or farmland, leaving small forest patches. The authors recommended shrew-focused sampling, including pitfall traps, in modified habitats to clarify occurrence and conservation needs.
