| The greater white-toothed shrew, Crocidura russula, ranges through much of western Europe. It frequently enters human houses and other buildings, and for this it is sometimes called the house shrew. Shrews have a superficial resemblance to mice, but they are not rodents. Along with their relatives the moles and hedgehogs, shrews are classified in the order of insectivores, a collection of species that resemble in many particulars the ancient creatures that evolved into the diversity of contemporary mammals, from rats to cats to bats to people to porpoises to ponies. |
