Unfortunately I have never seen it on any sponge.

Thanks very much. It looks as though the animal in the top photo is slightly 'younger' than the other one as it is smoother and has almost completely black rhinophores. You second photo [whch I have included close-ups of alongside] seems to show that the black gradually disappears from the rhinophores as the animal grows, which is what happens in the yellow species. Your photos also seem to show that the animal also develops low rounded bumps over the body as it grows as well.
Just add the sponge to your TO DO list - no urgency
