In the Summer of 2016, Eleanor Pawley (a Summer Research Bursary Student) and I collected some underwater footage of Sabellaria alveolata reefs (aka the Honeycomb Worm). Whilst only spanning about an hour and a half, the video (dark and grainy I know) captures a huge amount of activity, from starfish to crabs and fish, the reef comes alive when submerged. Interestingly, the worms do not immediately come out of their tubes, instead, they seem to wait until all air has evacuated (bubbles) and then appear under their porches.
