My favorite book in the whole world is “The Little Prince” by Antoine de Saint-Exupery! It’s about a pilot that crash lands in the African desert and the mysterious little man he meets there. He calls him “The Little Prince,” and hears about his life on the small asteroid B612 with a beautiful rose, and how he has been traveling near and far to learn about the universe, and who he has met. It’s written beautifully, with awesome illustrations! It’s even just been made a new movie!
As for similarities between bats and monkeys, they actually share most of the same bones, though these have been adapted for their different lives in the air and in the trees. There is only one nocturnal monkey, however, Aotus trivigatus, the owl monkey.
