You normally see Common Fruit Bats (Cynopterus brachyotis) hanging down, their feet clinging to some surface or other and the head pointing downwards. This is the normal resting position of bats (above). They have weak feet and are unable of run fast to evade predators. Hanging with their heads down allows them to immediately launch into flight by releasing their hold on whatever they are clinging on to.
There are two occasions when the bats head points upwards. One is when it is crawling up the surface (top). The other is when it is defecating (below). Here, it hangs on the claws of the thumbs with its head upwards and the hind limbs separated.
When in this position, please do not stand below…
Aha! Bats are wise enough to turn rightside up to poop & dirty YC’s floor; otherwise they will be messing themselves up bad! Clever! Ha ha!! 😉
