How do sea slugs and sea snails not perish from ocean salt?

You know like snails and slugs if you put salt on them they die How Do sea snails and slugs work?

In the ocean those slugs and snails have water content that is at equilibrium with their salty surroundings and they would actually die without it, say by being moved to fresh water. When a land slug is exposed to salt its internal water content diffuses in an attempt to reach an equilibrium with respect to salt concentration. If there is enough salt then the slug basically dries up and dies. It's similar to how your lips might get chapped/dry after eating salty tortilla chips.
