The smallest mammal in the world is the shrew. The tiniest member of the shrew family, the Mediterranean shrew, is about as long as your little finger and weighs less than a penny! Shrews live in most parts of the world.
If you see a shrew in a field or garden, you might mistake it for a mouse until you spot its long, sharp nose. These active animals are almost always hungry. They must eat more than their own weight in insects, worms, and snails each day just to stay alive. Their sharp teeth make it easy for them to kill and eat their prey.–Dick Rogers
