The Etruscan Shrew is a species of shrew, small mole-like animals, and holds the record for being the smallest mammal in the world by mass. They usually are only a couple inches long, and weigh less than 2 grams. While not completely nocturnal, the Etruscan Shrew is active during the night and usually stay near their nest during the day. Their diet is primarily made up of invertebrates like earthworms and insects, although they can sometimes hunt bigger prey like small lizards and rodents. When hunting, the Etruscan Shrew relies on its sense of touch much more than its vision to take out its prey. Birds of prey make up the majority of predators of the Etruscan Shrew, especially owls that are active during the night as well and can easily scoop up the small shrews when out in the open.
