| Mexican Shrews have been caught in traps baited with rolled oats, tuna, meat, and walnuts, which might indicate that they are catholic in their dietary habits, but might instead indicate that they are curious little animals who are not afraid to investigate a trap. They have been caught in southwestern Mexico from sea level to about 1,700 m. elevation. Usually they were found in damp habitat near streams, often in weeds, under rocks, or under logs. Little is known about reproduction, but one female, caught in June, was nursing a litter.
Mexican Shrews are large - for shrews - and have conspicuous ears. Both sexes have sparsely-haired glands on their flanks, but females' glands are smaller. An individual captured in June had new, fresh, dark grayish-brown fur and another was in mid-molt, with new fur on his tummy, flanks, and the back of his head, and his old, longer, paler, winter fur evident elsewhere.
Head and Body: 83-90 mm; Tail: 39-50 mm
