Took this picture in Fiji. I am not sure what you call the feather looking stuff wrapped up in the fire coral. I also have on video something that looks very similar but shaped like a star fish and swimming in midwater. I think Im talking about 2 different things here but the other I only have on video. If I were to name whats in the video I would call it a feather starfish. Hope you can help to ID both
Feather Star
Yes, I'd say that's a feather star, aka crinoid, with the fire coral.
