In one of my earlier post, I showed the photos of three "unknowns". And it must be my knowledge of marine life improving with time :) that I think I have an idea now what they could be!
Unknown No. 1: Sea hare, I think it looks quite similar to this one.
Unknown No. 2: compound ascidian, like this one.
Unknown No. 3: lace corals growing on a sea squirt
