Unlike the red-toothed shrews, the outer layer of their teeth is white. These species are typically found in Africa and southern Europe and Asia. This subfamily includes the largest shrew, the Asian House Shrew (Suncus murinus), at about 15 cm in length, and the smallest, the Etruscan Shrew (Suncus etruscus), at about 3.5 cm in length and 2 grams in weight, possibly the world's smallest living mammal (although some give this title to the Bumblebee Bat). Genus Crocidura, contains the largest number of species of any mammal genus.
When young must be moved before they are independent, mother and young form a chain or "caravan" where each animal hangs on to the rear of the one in front. This behaviour has also been observed in some species in genus Sorex.
