We have White Sea pens here. They inspired a thing in my book that looks like a liquid or solid depending on how fast they vibrate but is really a sentient community. The Sea Pen looks like a plant but is really a community of members with very specialized jobs.
these are really natural corals? I thought something bought at a gift shop when I saw them. How astonishing they are. If you are really begging, I will try and have a go at the tag challenge - it is ages since I looked at the challenges.
Well done!
