Etruscan shrew

There are a number of tiny shrews, but this pipsqueak takes the cake as the smallest. In fact, the Etruscan shrew is the smallest mammal in the world by mass. On average it weighs less than 2 grams, and has a body length of about 4 centimeters.

For such a tiny animal, however, it has a huge appetite — it typically eats about twice its own body weight every day!
