The smallest mammal in the world is the bumblebee bat (Craseonycteris thonglongyai). These tiny bats weigh only about 0.07 to 0.14 ounces (2 to 4 grams) and have a wingspan of about 6 inches (15 centimeters). They are found in Southeast Asia, primarily in Thailand and Myanmar, and are known for their distinctive pig-like snouts. Bumblebee bats live in limestone caves and feed primarily on insects, such as ants and termites. They are considered an endangered species, with only a few thousand individuals remaining in the wild, due to habitat loss and disturbance from human activities. Despite their small size, bumblebee bats play an important role in their ecosystems and are a unique and fascinating species of mammal.
