* Suncus etruscus on Mammal Species of the World.
The Etruscan Shrew (Suncus etruscus), also known as the Etruscan Pygmy Shrew or the White-toothed Pygmy Shrew is the smallest known mammal by mass, weighing only about 2 grams, although the smallest known mammal by skull size is the Bumblebee Bat. The smallest mature specimens of this shrew are thought to weigh about 1.3 grams and measure 36 mm (1.42 inches) long. This small mammal is 60 mm from the tip of the nose to the base of the tail; the tail is about 40 mm long. This shrew has a lifespan of 15 months. The Etruscan Shrew inhabits forests and brush areas between Southern Asia and Southern Europe. A forager, the Etruscan Shrew subsists largely upon insects. The Etruscan shrew has a heart somewhat larger than would be predicted for its body mass, i.e., 835bpm for an average body mass of 0.0024kg. The heart beats 14 times per second.
