I presume that these are eggs! but what laid them? found lots at Whitsand Bay, Cornwall, on rocks regularly covered by tide - would also quite like to know what the orange stuff is too (could it be sponge??)
Well, the "parents" seem to be present on the image. Compare http://islaynaturalhistory.blogspot.com/2011/05/dogwhelks-nucella-lapillus-and-their.html.
It is hard to tell from the image what the orange stuff is - it may be sponges like http://gallery.nen.gov.uk/image88720-.html, it might also be sea sqirts like http://fieldguides.eol.org/fieldguide-view.php?guidekey=357&eol_id=2774108&sci_flag=1.
well half the question has been answered!!
thanks for the whelk eggs reference :)
the orange 'stuff' doesn't really look like either of the other two references - in reality it's much 'drier'
When I clicked the image it filled my screen so I missed that I could zoom in further on it .
It now looks more like sponges than sea squirts. Sponges are hard to identify and not my subject at all, but here is a page that might be of some help: http://www.habitas.org.uk/marinelife/sponge_guide/.
The orange stuff IS a sponge,
Hymeniacidon perlevis (formerly known as perleve).See
It's 1 of the 3 most abundant onshore sponges, with Halichondria panicea (breadcrumb sponge) & cliona celata (boring sponge), & also the furthest upshore. In the Gower (S.Wales) it forms a 'zone' along the rocky shores. It alsolacks the 'volcanic-like' openings of the breadcrumb sponge
