Three different boring sponges side by side. Probably Pione vastifica (orange), Cliona celata s.l. (yellow) and an unidentified blue species. I don't know of a blue clionaid species in the Adriatic.

These are screenshots from a towed camera at 60-65 m depth. The tow shows hundreds of meters of these scattered white structures. I considered glass sponges, but I think in many I can see two openings. They are stalked as well (or at least seem to be in some frames, tried to include a screenshot). Not too sure about the size, 5-10 cm I guess. Any clues?

Please ID the bright pink species if it is a species. This is at the bottom of a quite deep but small crevice in a rock that I think is possibly filled with rain water rather salt water or maybe a mixture of the two.
