Dear Stephaine,
Sea Slugs are specialised snails, and many of them, such as the nudibranchs, have 'lost' their shells. If you go to the What is a Slug? page you will find some information and links to other pages which discuss this topic.

Snails are molluscs, a Phylum of animals that also includes squid, octopus, and clams. Fish on the other hand are chordates (including vertebrates), a Phylum which includes all animals with a backbone - fish, frogs, birds, mammals etc.
Best wishes,
Bill Rudman
