Hi all,

I took a picture of a seafan in the Philippines, Bohol to be precise. It does look like it would be covered in tiny bubbles:

Does anyone know, what these tiny bubbles (skeleton shrimps for reference) are?
Thanks!

If the phenomenon was localized to a single branch, they might be the eggs of some gastropod. If, on the other hand, it was a generalized phenomenon across various colonies, it could be a gamete release.
In the Mediterranean, red gorgonians (Paramuricea clavata) release male and female gametes during the summer. I have witnessed this phenomenon a couple of times, and in the hours preceding the actual release, the fans are covered by these gametes which then detach and float away.
