Can anyone tell me what this is or these are? I originally thought it was a worm but upon closer inspection there are breaks menaing it is not completely conected. It looks like they may be eggs and I noticed that the Cerith Snail nearby has not moved since I noticed it a few hours ago. My guess is that they are snail eggs. Sorry for the clarity of pics as they are the best I could get at this time.
