Single Green Star Polyp sitting on gravel

[betareef]

Of course I have read that GSPs love to spread, and I expected my small patch to spread over it's rock, but today I see a single polyp, fully extended, and sitting in the gravel near the rock that the colony is growing on, slightly beneath the edge os it.

So, is this yet another way they spread? Do they drop polyps into the water flow?

they do grow over sand but i wouldn’t say they grow underneath it and sprout somewhere else.

perhaps a snail or crab unintentionally ripped it off? and then floated there

I wasn't thinking that. I was thinking it had dropped down from the main GSP patch.

I never seen my drop anything. But my does branch, first it covers the stone/ rock and then it branches out.

This picture shows it:

Yes I think mine has started to to that on the side where it is overhanging.

Maybe better picture when polyps are full retracted.

My guess would be it grew onto a piece of gravel, then the piece somehow got pulled loose.
