we need to know what you're asking.
You should try to add a few notes to your sightings.
There are a number of 'subjects' in the picture - which is EXCELLENT.
I have identified the egg mass for you (I'm pretty certain that's what you're asking) but the starfish could be the subject of another posting; it is most likely the Common Star (Asterias rubens) so you could post it with your own ID.
Then you could move to the Spirorbis, the Pomatoceros and more - that's why the picture is so good.
