The bats are often seen hanging themselves upside down on trees. The bat could not be seen standing or sitting upright.

The reason behind this topsy-turvy position is the weak bones. The bones of feet of bats are so weak that they could not bear the weight of their body.

When the bats are on ground they put their entire weight on the ground and just lie down. In this way the feet are saved from carrying their weight.

That is why the bats get themselves hung on the branch of the tree, so that the body weight is not on bones but on the stretched or taught muscles and tissues. The bats hang in this position to save the bones of their feet.
