Planorbella trivolvis, an air-breathing ramshorn snail. Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers.
These fresh water snails are present in aquariums and ponds, as well as in wild areas. They are also commonly referred to as tadpole snails or pouch snails. They eat algae, diatoms and detritus, including dead leaves. The populations are regulated by the abundance of food and space. They are widespread, abundant, and tolerant to pollution.

Others will however intentionally keep bladder ...
