- You may have heard the "fact" that snails and slugs "melt" when exposed to salt. A snail's mantle (its outer covering) is a selectively permeable membrane (though not as permeable as a cell membrane). Water can freely pass through the snail's mantle but solutes like salt cannot. The snail's body contains roughly 30% solute and 70% solvent (water). The salt on the surface of the snail's body creates an environment that is 100% salt. iarrow_forwardThe pathway that can move highest rates of sodium ions is: A. Sodium channels B.
