Definition
  1. Noun:
    • A major taxonomic class within the phylum Mollusca: "Class Gastropoda" is the scientific name for the large and diverse class of mollusks that includes snails, slugs, and their relatives. Members of this class are characterized by a single, usually coiled shell (though it may be reduced or absent, as in slugs), a muscular foot for locomotion, and a distinct head with sensory tentacles.
Usage Examples

Advanced Usage
  • In taxonomic hierarchy: Used in formal biological classification.
