What is on my hammer coral?

Hello all I realized my hammer coral has some weird algae looking thing coming out of it? I was wondering what this could potential be?

Mesenterial filaments ?

Oh so they are stinging tentacles? Interesting I've never seen so many. I also feed my corals and fish a lot.

Sort of, they're not like sweeper tentacles but more like the polyps guts/stomach.

Sometimes seen while digesting food, defending itself or possibly stress.
