What do bats use their legs for?
You are correct.
Hmmm... that's not right.
They claws on their feet are very strong and that is what they use to allow them to hang upside down while they sleep.
As long as it has a textured surface – something they can grip on to – and not a shiny or smooth surface, the bat can climb it.
The entire body of the bat is covered with fur. This helps to keep it warm enough for survival.
They have a small dot like nose but they have an excellent ability to smell with it.
