[Coral-List] Scleractinian asexual reproduction

I work at a lab on the Swedish west coast where we keep the cold-water coral
Lophelia pertusa live in aquariums. We have recently observed a potential
novel mechanism of asexual reproduction. On the top of a branches (maybe 1
cm from the tip) has does it look like the calcium skeleton is (reabsorbed
or simply dissolved) and on both side of this "break" is a tentacle crown
formed. It has not released yet but when it does I guess this little tine
polyp can drift away in the water for quite a distance.

I am curious whether if anyone has observed anything similar?

all the best
