The Etruscan shrew (Suncus etruscus), also known as the Etruscan pygmy shrew, white-toothed pygmy shrew and Savi’s pygmy shrew, is the smallest known extant mammal by mass, weighing only about 1.8 g (0.063 oz) on average.[3][4][5][6][7][8] (The bumblebee bat is regarded as the smallest mammal by skull size and body length.[3][9])

The Etruscan shrew has a body length of about 4 cm (1.6 in) excluding the tail. It is characterized by very rapid movements and a fast metabolism, eating about 1.5–2 times its own body weight per day. It feeds on various small vertebrates and invertebrates, mostly insects, and can hunt individuals of the same size as itself. These shrews prefer warm and damp climates and are widely distributed in the belt between 10° and 30°N latitude stretching from Europe and North Africa up to Malaysia. They are also found in the Maltese islands, situated in the middle of the Mediterranean Sea.[2][5] Although widespread and not threatened overall, they are generally uncommon and are endangered in some countries.
