| The first Mexican Long-tailed Shrew to be described scientifically was found almost two miles high on a mountain in Jalisco, Mexico. This species is fairly wide-ranging and not thought to be at risk. Shrews are born with a full set of 26-30 teeth, unlike most mammals, which, like humans, are born toothless, or with "baby teeth" that are replaced by adult teeth.
Total Length: 106 mm; Tail: 36 mm
