Two, the types of freshwater snails

When they dive into the water, they can breathe and even float on the water surface by the buoyancy of the gas in the cavity and use the surface tension to adsorb under the water surface with their gastropods, and when they float on the water surface, they will use the upper and lower strands of their longitudinally flattened shells as the propelling force for their bodies.

3. Tantalum gastropods
