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).
