1. Bumblebee Bat (Craseonycteris thonglongyai)
Last—and least!—the bumblebee bat is the smallest mammal in the entire world.* They live in limestone caves near rivers in Thailand and Burma, in colonies of about 100 bats. They are a petite 1.1–1.3 inches (29–33 mm) in length, and weigh 0.071 ounces (2 grams)—that’s roughly the same as a single raspberry! Their long-tipped wings allow them to hover in mid-air, and they have a handsome pig-like snout.
*While the Etruscan shrew has a lower mass, the bumblebee bat has a smaller skull and a shorter overall length.
