Is a slug an amphibian

No, a slug is not an amphibian; it is a mollusk. Specifically, slugs belong to the class Gastropoda, which includes snails and other similar creatures. Amphibians, such as frogs and salamanders, are vertebrates that typically undergo metamorphosis and have a life cycle that includes both aquatic and terrestrial stages. Slugs, on the other hand, are primarily terrestrial and do not undergo such transformations.
