Shrew

Shrew

Shrew (family Soricidae), any of more than 350 species of insectivores having a mobile snout that is covered with long, sensitive whiskers and overhangs the lower lip. Their large incisor teeth are used like forceps to grab prey; the upper pair is hooked, and the lower pair extends forward. Shrews have a foul odour caused by scents gland on the flanks as well as other parts of the body.Tail length varies among species, some being much shorter than the body and others appreciably longer. The brain’s cerebral hemispheres are small, but the olfactory lobes are prominent, which reflects less intelligence and manipulative ability but an enhanced sense of smell. The 26 to 32 white or red-tipped teeth are not replaced during the animal’s life (milk teeth are shed before birth).
