ID Please - Strange White Line Pattern

[fitzgeraldjw]

So I woke up yesterday morning to find a very cool, but odd circular pattern on my glass. It doesn't appear to be anything alive, but I have no idea what would have left this. It's a little larger than a quarter. Has anyone ever seen this and if so, what is it? (sorry for the bad photo, my iPhone fails when zooming)

There wasn't a picture in the link.

If it looking anything like this, they are snail eggs -- the pattern will be different depending on the snails (( Not all snails lay eggs, some mass spawn ))

Not sure why the picture link didn't work. Here's it embedded: doesn't look like your picture but you think it's still snail eggs?

Yep, still say they are snail eggs.

I have had that pattern before, but which snail laid it is escaping me right now.

that is the eggs of a cerith snail

That's pretty awesome and amazing the patterns they make. So I don't suspect there's anything in particular I need to do except not running over them with my Mag Float:)

--oh and thank you both for your responses, glad I learned something new today:)!

+1 on snail eggs, which won't hatch. I'd clean them off unless you like pretty patterns on the glass :).
