| Shrews in the genus Cryptotis have tiny ears that are almost hidden in their fur, shorter, broader feet than Sorex shrews, and shorter tails. All shrews have shorter tails than mice, however. A mouse's tail is often longer than its head and body. Sorex shrews' tails are about three-fourths of the owner's head and body length, and Cryptotis shrews' tails are at most half head and body length. All shrews have five toes on each foot. Mice have four toes on the front feet and five on the back. Apparently there is another significant difference, at least to cats: they catch and kill shrews, but seldom eat them, apparently not liking the taste. Nelson's Small-eared Shrew is known only from the locality where it was originally collected, on a mountain in Veracruz, Mexico.
Head and Body: 67-80 mm; Tail 22-33 mm
