Sesame seed looking things

First off is there a site I can go to to ID things (hitch hikers) I find in my tank? I want to try to figure it out on my own first then ask questions.
Now, without a good camera and cant figure out how to upload, I got my shipment of snails in and there are these white sesame seed looking things on some of them. I didn't realize they were living so didn't worry about them, but now theres about 20 or so on the glass and on my overflow in both my DT and fuge, what are they and are they bad? How do I get rid of them if there bad? pic them off one at a time?
I wont be able to check back in till this afternoon.

 

look up nerite snail eggs

 

Yep, John just also replied back to my post on his forum.
Thank you very much Grinder37
PS anybody know of a site devoted to pics and ID of inverts and hitch hikers? If I don't know what it is I cant search it and the best way for me to learn is try to figure it out or ID it myself first then ask questions. I'm learning tons of things and understanding it such as water chemistry and why it's so. This can only make my system better and give back to those who need it like so many have gave to me.

 

Check out the sticky's in the "I'd this" forum.Hope that helps.
