You can review the earlier post here, but I'm excited to share even better footage of this amazing brittle star in action.
Take a look!
This video is shown in actual time. Note the extremely long, flexible arms of the brittle star; the impressive digging behavior (the sand grains appear to be "boiling"); and close-ups of the tube feet flicking upwards. The tube feet are visible on the under sides of the arms (below the spines) — watch for them especially during the interval at 30-35 seconds.

I hope you dig this video as much as we did!
