Are garden snails and pond snails the same?

While both types of snails are mollusks, gastropods, to be more specific, the land snails have developed lungs to be able to breathe on land. Aquatic snails have gills, special organs that remove oxygen from the water. For this reason, land snails will drown if left in a bucket of water that they cannot escape from. Aquatic snails do not have the thick slime that land snails have and will quickly dry out,( if they do not suffocate first) when left out of the water.
