Green sacs about 2cm with stalk attaching to sand, also seen attached to seaweed on sand flats at very low tide.
No interactions present.
looking around on the web that does seem to be what it is likely to be. Thank you
I have agreed the first and only in two years - risky!
Change the group to invertebrates soon.

I seem to have promoted some cross-expert debate.
Mike Kendall - you have rightly questioned the Eulalia viridis ID.
There appears to be a number of green egg masses and some are quite small, less than 1cm.
I have collected these larger ones - ones 'we' think might indeed be Eulalia viridis from weedy pools, sandy tidal pools and the lower drying sand. That they were the same (identical) I have no doubt. Conditions must exist for them to be washed out of pools and for the transparent strand to become locked in the sand. Indeed that's where I photographed them.
