Can you circle the things you want identified? I'm not sure I'm looking at what you're describing.

My first WAG (confidence level = 5%):
1 - Oyster
2 - Bleached Polyp or Anemone
3 - Colonial Tunicates

I don't know how to circle it so I will do my best to describe it.
1. The first and second picture is the same.
The middle lower white circular thing with the spikes. It looks hard to me not like an anemone type.
2. The 3rd picture is the maroon thing with the whole in it. Middle upper part of the picture.
3. To the left bottom of the maroon thing is a round bubble thing. Clear round bubble.
Hope this helps.
Thanks,
Andrea
