By mass, the smallest mammal is the Etruscan shrew which weighs less than one gram and is between 1.5 and 2 inches in length. By skull size and length, the smallest mammal is the bumblebee bat (aka Kitti's Hog-nosed Bat) which is a little over one inch (30-40mm) in length and also weighs between 1g and 1.5g.
