What is this?

Hey everyone, just noticed this in my tank yesterday. it is on the glass, right next to my skimmer pump. If you look, you can see its shadow on the pump motor. I do not see it anywhere else in the tank. Please hlep, I don't know if it is something I need to remove, or just let it be.

Cerith Snail eggs - I wouldn't expect any to survive to adulthood in your tank, but the eggs won't harm your tank at all.
