IDK what these could be several different creatures, maybe sponges but not sure. the rock sits in a low flow and the rock sits where these creatures on the back don't get any or very little light.

any suggestions would be great.

Top left is a pineapple sponge, the rest of them also look like different kinds of sponges as well.

The clearish one looks like a tunicate. The rest are various sponges.

They are all sponges, top 2nd from left is Scypha barbadensis. At the very bottom of the 2nd photo is another Scypha sp. with a spirorbid worm to its immediate right.

He meant Sycon sponge. Pineapple, sycon, white lattice, and I'm not sure what the clearish one is but it's definitely a sponge.

It's tough to call from the photo, that could be a tunicate after all.

the reason I say tunicate is the two vent holes and no evidence of sponge skeleton. The test would be to touch it and see if it expels water and/or slightly shrinks. Plus the general shape is very similar to a common purplish clearish tunicate from the gulf.

The clearish object is definitely a tunicate. You can see the internal organs, which tunicates have and sponges don't.

It's hard to tell from the photos weather it has organs or has just grown over other life, you can see little white specks that it has grown over and it almost looks like another siphon on the top left. Touch it and see if it reacts.

They are definitely organs. The stomach and intestine are distinct and right where they should be in a tunicate.
