There are approximately 68 different microbat species in Australia, ranging from the tiny Little Forest Bat (4gms) to the Yellow-bellied Sheathtail Bat (45 gms).
Anatomy for Flight
A flying-fox’s arm and hand bones are similar to our hands, with four fingers and an elongated thumb. On the end of each thumb is a hook. Flying-foxes use these important tools to invert when excreting waste. They can be used as defensive weapons and as grappling hooks to climb. The hook is also useful to bring food sources closer within reach. A strong flexible membrane forms the wings.
Flying-fox bones are light and their upper bodies very muscular to enable flight. These adaptations mean they have comparatively weak legs and are unable to stand upright. Hanging by their feet requires little effort due to leg tendons that ‘lock’ the claws in place on the branch.
