The American pygmy shrew is the smallest mammal native to North America and is one of the smallest mammals in the world, just slightly larger than the Etruscan shrew of Eurasia. Its body is about 5 cm (2 in) long including a 2-cm-long tail, and it weighs about 2.0 to 4.5 g (0.07 to 0.16 oz). [ 9 ]
The shrew usually has 30 teeth, but the 4th upper intermediate tooth is very small (rudimentary), and is absent in some individuals. [6] Near the mouth grow a dense array of short whiskers, which the shrew actively uses to search for prey, especially in the night. [7] Dimorphism in body features between males and females is absent. [10]
