A small (1-2cm) green jelly like blob attached to the sand/rock. Many of them in the harbour at low tide.
No interactions present.
I've seen things I have identified as Sea Gooseberries (http://natureinfocus.wordpress.com/seashore-creatures/sea-gooseberry-wha...) on beaches before - but they've never actually been green! The attachment to sand may be due to buried tentacles.
See id above - I'm pretty sure there are no green sea gooseberries except for iridescence colours.
Rob, if you agree with Dave, it will be interesting to see what happens to the 'Likely ID' function when you click the 'I agree' button on his observation. At the moment your reputation is tipping the balance the other way!

Glad to see this works! They're clearly not Sea Gooseberries if you enlarge the photo, which I probably should have done first...
Yes, a good little test of the system.
In the hope that Jonathan, Rob and Dave may come back to this I invite you to http://www.ispot.org.uk/node/326557#comment-109838
Where I have cast some doubt on the ID of U.viridis.
I shall offer this as an ID for one or two of the viridis posts to feel the ground - maybe get more informed opinion.
What do you three think?
It may be that jr6765 (the Poster here) has left the arena.
I have removed my agreement as I'm no expert in this area and can't think now why I thought to agree. This was done in the early days of iSpot, so I think it was for a test.
I'm not saying the det it right or wrong, just that my opinion is not of value here.
I'm also no expert - will be interesting to see if anyone else contributes to this - will be on the lookout for polychaete egg masses on my next trip to the beach!
Do not abdicate as I would say that Naturalists' opinion (you are) is what we are after here. There is little chance that we can be certain which creature laid these 'iSpot' egg-blobs but we can continue to pursue the goal and, hopefully, put it to rest with some definitive sightings.
I have accumulated enough evidence, short of seeing the process, to propose that MOST of these spring sightings are, probably, of the polychaete (worm), Phyllodoce maculata (I am tired of the iSpot dictionary correcting it to maculate!).
Have been looking into this, (largely by googling "Eulalia viridis eggs").
Just to complicate things more it seems that unlike the European E.viridis (eg Germany, Scandinavia) ours (since the 1990's) are deemed a different sp's EULALIA CLAVIGERA (also prob found in eg Spain). This is from the Students guide to seashore (Fish & Fish) [found in my search as google-books], & it also says "breeding has been recorded in july & August"
The new RSPB handbook by Maya Plass P.100 has the new name for the greenleaf worm & "previously mistaken for Eulalia viridis" but also says it produces "bright green gelatinous blobs... in early spring". (It's quite possible they've more than 1 breeding period) Anyway as Maya Plass appears on, eg, Springwatch it'd be a good question to ask her how sure she is that viridis lays these blobs.
Also "Bristleworm (Eulalia viridis) Larva hatched from egg mass - x62 - Plymouth, England" at http://www.diomedia.com/public/;jsessionid=2A3A5DE1A9C29500840383E751B85...
A researchgate.net abstract of 1975 [reproductive biology of E.viridis(Muller)] criticised an earlier 1938 one on devpmt of larvae from cocoons "purported to be from E.viridis" & reckoned his conclusions "not appropriate to all populations of E. viridis" at http://www.researchgate.net/publication/231940969_Reproductive_biology_o...
I'm resistant to saying all,or even most, of these blobs are Phyllodoce in part as viridis is so abundant ,whereas photos of P. maculata are hard to find; but also maculata's habitat which Hayward & Ryland describes as "muddy sand, under stones, & mussel beds (eggs dark orange or green). Most of the blobs I've found on the Gower were in rockpools.
But I agree with dejay (who's put together a lot of good evidence) that we can't be certain.
Yes, a good summary Chris (as always)
I think we can do little more than read and ask at the moment. One thing is becoming clear - that several marine worms lay eggs in green cocoons - their seasons overlap!
Like many people I was lured into assumptions by 'definitive' statements on the web, some of them mentioned in my first E.viridis posting
http://www.ispot.org.uk/node/324203 and later in http://www.ispot.org.uk/node/326557
The most compelling evidence (for Phyllodoce maculate) is Picture 8 here -
In due course, I may make another post on the Green egg mystery because I have more pictures of green blobs and less evidence for Eulalia viridis.
