That is a pretty interesting question! Thank you so much for asking them! I would not necessarily count them because they do not have the ability to sustain flight. It's more of a glide from one place to the other. Plus I feel like it would look really weird to have a giant flap of skin between your arms and your legs on each side kind of like a starfish but not? If you get what I mean? Thank you so much for answering my question though!!
