Usually the eggs of aquatic snails resemble thick mucus rounded size, soft and elastic. With the maturation of the eggs she hardens and changes color from yellow (the color of melted milk) to green and brown. But members of the family Neritidae of the eggs already hard, as they have a shell in the form of a capsule, which fits just about hundreds of embryos. Initially, this container is white and rather soft, but gradually gaining its walls, the fortress, and the color changed to yellowish-brown. Freshwater representatives of this population size capsules a bit more than those who dwell in the seas and oceans.
