Although generally nocturnal, the Common shrew can be active during bot h day and night. It usually has alternating periods of rest and activity during the 24 hour day. Each period of activity lasts for 1 2 hours on average, after which the shrew will rest, generally in its nest.
Juvenile shrews have lighter fur until their first moult. The common shrew has small eyes, a pointed, mobile snout and red tipped teeth. It has a life span of approximately 14 months.
Shrews are active day and night, taking short periods of rest between relatively long bursts of activity.
The common shrew's carnivorous and
insectivorous diet consists of insects, slugs,
spiders, worms, amphibians and small rodents. Shrews need to consume 200 to 300% of their body weight in food each day in order to survive. A shrew must eat every 2 to 3 hours to achiev e this goal.
A shrew will starve if it goes without food for more than a few hours. They do not ibernate in the winter because their bodies are too small to store sufficient fat reserves and as they have a short fasting duration.
