These are two short videos of the head standing behaviour. They are short due to the fact that they don't stay still long enough. They move out of the camera area too quickly, or by the time you've focused they've jetted off. You can see the lateral compression in the 5-6 DPH video as well as the pigmentation. I hope these help those who have not seen this in person to better understand what's being talked about.
