Are these eggs ?

[vdubreefer]

Hey everyone while attending reef a palooza I picked up some amazing pieces of corals , whilst in quarantine I've a couple weird things and want to make sure I'm not going to put anything into my DT, so I was able to get some close up photos of what looks like a mucus like substance on a couple of the corals skeletons below the polyps

This is the blasto I got ;

And these are off one of the acan lords I got;

I'm trying to be diligent and make sure not to introduce hitchhikers as much as possible but I don't entirely know what to look for ?
Thanks for the help and input

I think the white might be a sponge
