The A to Z list
Animals that start with B
B is a letter of extremes. It holds the bumblebee bat, which at around two grams is the smallest mammal on Earth, alongside the bear and the boa constrictor. The butterfly and the betta fish are here too, and the bushbaby, a small African primate with eyes so large it cannot move them in their sockets and swivels its whole head instead.
7 animals in the library start with B, from the bear to the butterfly. Most of them live in Asia and North America.
