In General:

Shrews are generally mouse like in appearance.  They tend to have a long, pointed nose and soft, gray-brown fur.  The shrew family contains a species that is the world's smallest mammal.  It measures about 2.5-5 cm and weighs less than 2 grams.  Most species of shrews are terrestrial but there are some species that are semi aquatic or arboreal.  The family of shrews has been successful in invading almost every environment except for the polar regions.  Their habitats range from forests to grasslands to deserts.  Although shrews are active both day and night, they are mainly nocturnal organisms.  Shrews forage often in search of food to fuel their incredibly high metabolic rates.  The diet of shrews, in general, consists of insects, worms, small fish, and frogs.  Though they have been known to kill prey many times their own size such as mice and other shrews.  The shrews will also eat carrion and plant material when other resources are scarce.  Shrews combine poison-tipped teeth and sometimes echolocation with a fierce foraging lifestyle that allow live with a small body size (Funk & Wagnalls, 1999).
