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.
All shrews are tiny, most no larger than a mouse. The largest species is the Asian house shrew (Suncus murinus) of tropical Asia, which is about 15 cm (6 in) long and weighs around 100 g (3 + 1 ⁄ 2 oz) [2] The Etruscan shrew (Suncus etruscus), at about 3.5 cm (1 + 3 ⁄ 8 in) and 1.8 grams (28 grains), is the smallest known living terrestrial mammal.
They range in size from the Etruscan shrew, one of the smallest mammal species at 3 cm (1 in) plus a 2 cm (1 in) tail, [1] to the hero shrew and Thor's hero shrew, at 15 cm (6 in) plus a 10 cm (4 in) tail. Crocidurines primarily eat invertebrates, small mammals, frogs, toads, and lizards.
They come in a variety of body plans in contrasting shapes and sizes, and range in size from the Etruscan shrew, at 3 cm (1 in) plus a 3 cm (1 in) tail to the moonrat, at 46 cm (18 in) plus a 30 cm (12 in) tail.
It is the smallest species of bat and may be the world's smallest mammal, depending on how size is defined. The main competitors for the title are small shrews; in particular, the Etruscan shrew may be lighter at 1.2 to 2.7 g (0.042 to 0.095 oz) but its body is longer, measuring 36 to 53 mm (1.4 to 2.1 in) from its head to the base of the tail.

This subfamily includes the largest shrew, the Asian house shrew, Suncus murinus, at about 15 cm in length, and the smallest, the Etruscan shrew, Suncus etruscus, at about 3.5 cm in length and 2 grams in weight.
There is a positive relationship between mass at birth and length of gestation in eutherian mammals. [17] Larger mammals are more likely to produce a well-developed neonate than small mammals. Large mammals develop at an absolute slower rate compared to small mammals.
