Which coral can send tentacles up to 2 foot?

Found this web coming from this mushroom looking thing (atlist is what I’ve been thinking it was till now) throwing this web looking thing from the sand bed all the way to the surface! That’s 2 foot deep! Never heard off any coral sending tentacles that far. Anyone got any idea what this ugly thing is?

Thanking you

Wow that's really surprising. I don't think it's actually a mushroom. It looks more like a leather to me but I didn't think leathers had tentacles like that.

My guess is a vermetid snail in the coral

I will second the vermetid theory

Sorry and thanks guys

It is a benthic ctenophore just found out, and it just flew out of the window too

How did you come into possession of it? Was it a hitchhiker?

Yeah, I wouldn’t be buying it for sure, for what I read it’s a bit like a flat worm, last thing I want is a reef full of them.
