what on the acropolis

Good afternoon. There is an opinion that this is on the acropora? (circled) It doesn't look like a polyp... unfortunately, there is no better quality photo. (seller's photo)

I'm not sure, but it looks like a broken twig and "snot"..... If we assume that it's some kind of creature.... like a nudibranch (it looks similar), then they don't live in the acres....

It looks like a filter.... You can also "try on" this little worm for the first photo, but the white color is confusing....
