Can anyone help in identifying what this is.

Thank you in advance

It looks like the egg trails my cerith snails make on the glass. Never seen them on rocks though so I could be wrong.

Thank you! They didn’t last long. I noticed them this morning but when I went to look at them just a little bit ago my emerald crab was eating them off the rock.
