I was using my magnet and came across this on the glass earlier today. You can see on the right side where I nipped it before taking the picture. Any ideas?

oh wow! pretty cool. surpisingly my first time ever seeing this. and i definitely have a big variety of snails in there. I'm assuming the odds of these actually maturing are very slim though.
