Trivia: What is the world’s smallest mammal by weight?
Etruscan shrew
Pygmy possum
Micro mongoose
Nigerian dwarf goat
The correct answer is Etruscan shrew
So why is this answer correct? : With an average weight of around 0.063 ounces, the mole-like Etruscan shrew is the smallest known mammal by mass. Located in areas across Eurasia, the shrew builds colonies in crevices and other natural shelters, eating ants, crickets, and mealworms. At their maximum, Etruscan shrews reach about two inches in length, and the animals’ hearts beat an average of 25 times per second, contributing to their very high metabolisms.
