What is the smallest mammal in the world?

The world’s smallest mammal

The world’s smallest mammal is the Etruscan shrew (Suncus etruscus), also called the Etruscan pygmy shrew. This tiny mammal is only about 3.5-5.2 cm long and weighs around 1.8-2.7 grams. It is found across Southern Europe, North Africa and parts of Asia, usually in warm habitats with dense ground cover, and it is rarely seen due to its small size and secretive habits.

The Etruscan shrew is an extremely active, fast-moving animal that hunts almost constantly, feeding mainly on insects and other small invertebrates. Because of its very high metabolism it has to eat frequently just to survive, and despite its tiny size it is a skilled and relentless predator.
