In Dragonvale, when you get a shrine to level up, your dragons can go beyond level ten. When you level them past ten, a sphere shows up over the dragon's head. I'd like to know what they do or what they are.
The spheres are merely there to show (to yourself and your visitors) that your dragons are higher than level ten.
The shrines will show that your dragons are able to level past ten (or fifteen if it's gold), but the orbs show for each particular dragon that is above level 10.
