| Very little is known about San Cristobal Shrews. They have been found only in two locations in Chiapas, Mexico. Presumably, like all Sorex shrews, they are nervous little creatures: a frightened shrew's heart can beat at 1,200 times a minute. Trapping live shrews is a challenge, because they can die of fright, and establishing them in a laboratory setting, where they can be studied, is very difficult.
