The white-toothed shrews or Crocidurinae are one of three subfamilies of the shrew family Soricidae.

Contents

The outer layer of these shrews' teeth is white, unlike that of the red-toothed shrews. 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. The latter is possibly the world's smallest extant mammal, although some give this title to the bumblebee bat. Crocidura contains the most 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 Sorex species.

Shrews are small mole-like mammals classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, West Indies shrews, or marsupial shrews, which belong to different families or orders.

<i>Crocidura</i> Genus of mammals

The genus Crocidura is one of nine genera of the shrew subfamily Crocidurinae. Members of the genus are commonly called white-toothed shrews or musk shrews, although both also apply to all of the species in the subfamily. With over 180 species, Crocidura contains the most species of any mammal genus. The name Crocidura means "woolly tail", because the tail of Crocidura species are covered in short hairs interspersed with longer ones.

A unicuspid is a tooth that has only one cusp.
