| There is little specific information about this shrew, which occurs at elevations above 2,000 m in the mountains of southern Mexico and Guatemala. The distribution of some shrews is documented by their remains appearing in owl pellets. Owls prey on shrews, gulp down their catch, and then regurgitate the parts they cannot digest. Shrew skulls are easily distinguishable from rodent skulls by their teeth: shrews' teeth are all in a row, with no gaps between them. Before DNA analyses were possible, subtle differences in the skull and teeth were used to distinguish one species of shrew from another.
