The genus Cryptotis is a group of relatively small shrews with short ears which are usually not visible and short tails. This article is about the animal; see also The Taming of the Shrew for the use of this term to describe a person. ...
They are found mainly in Central America; the Least Shrew, C. parva, is the only species of the genus found north of Mexico. The genus occurs as far south as northern Peru and as far east as western Venezuela in South America. It is the only insectivore genus found south of Guatemala. They are red-toothed shrews; species in this group have 30 teeth. Since 1992, Neal Woodman (in corporation with Robert Timm) at the United States National Museum has been in the process of revising the genus. To date, this has resulted in an increase of number of species from 12 in 1992 to 30 now. Central America is the region of North America located between the southern border of Mexico and the northwest border of Colombia, in South America. ... Genera See species list The Red-toothed shrews or Soricinae are one of two subfamilies of the shrew family Soricidae, the other being the White-toothed shrews or Crocidurinae. ...
