I named this coral "Bad Hair" All those things sticking up are Rope Sponges. The little bushy things in the sand on the left are corals---animals, not plants. More on them in another post.
Looking a little closer, those yellowish corals are Maize, or Butterprint corals, a type of brain coral. The wine colored worm looking things in the bottom right are rope sponges, I don't have my book here, so I can't give a better name. Over on the left is a spotted looking thing, a Great Star coral, with a Christmas Tree worm. (click on the image for a larger view, then the back button to come back here)
The two star corals have different kind of algae that give them their, in this case, pink or orange/rust colors. The rust colored coral is feeding a little, the polyps semi-open.
OK, thanks for stopping by!
