As part of OU field study. Seen in rock pools on Lower shore & 10m in on Middle shore.
No interactions present.
There is the possibility of confusion with Mastocarpus stellatus. Both are red fan-shaped seaweeds found on rocky shores in your area. I think the easiest way to distinguish is that the frond of C. crispus is generally flat, while that of M. stellatus is rolled under at the margins. I have found this book very useful: Seasearch guide to Seaweeds of Britain and Ireland 2010 Bunker F. St. P. D., Brodie J.A., Maggs C.A. and Bunker A.R.
I don't think we can really tell from the picture, though I am pretty certain it is Chondrus crispus. It is important with seaweeds to try to get a couple of views of the fronds or add some descriptive details.
Take a look through our Seaweed's gallery, link below, to see the sort of detail that is preferred when giving agreements.
Not a moss but an Alga, so to avoid confusion could you please use the tag algae, this will better aid the Algae/Seaweed experts in finding your upload and giving an agreement or a correct ID, thanks in advance,

I do not think the poster has been on the site for some time, (see their Track tab) so the tag you ask for may not be made. Only posters can add tags to their posts; there are no doubt good reasons for this, but it can leave a post with misleading information.
