The text describes the bumblebee bat as the smallest bat and mammal, weighing 2 grams, 29 to 33mm in length, with a 170mm wingspan.
The bumblebee bat, also known as Kitti's hog-nosed bat, is frequently cited as the world's smallest bat and mammal by body size, supporting the claim with authoritative references. Web sources confirm the bumblebee bat weighs approximately 2 grams and measures between 29 to 33mm in body length. However, the wingspan claim of 170mm is contradicted by multiple sources which state a wingspan of 11 to 13 cm (110 to 130mm).
