All of us have seen dragonflies around ponds and lakes, but there's a lot more to these fascinating creatures than perhaps we realized. They really are amazing and their anatomy and behavior is unique as the video below illustrates.
It's a bit long (18 minutes), but if nature is an interest of yours, once you start watching you'll probably want to watch the whole thing. It's certain that you'll never look at dragonflies quite the same way again, and you won't take them for granted.
One question you might keep in mind as you watch is how such amazing engineering ever could've evolved through chance genetic mutations.
