Proper noun: * Family Paguridae: The taxonomic family name for a large group of decapod crustaceans commonly known as hermit crabs. This family is characterized by their soft, asymmetrical abdomens, which they protect by inhabiting empty gastropod shells.

Usage

• The word Family Paguridae is used exclusively in scientific and zoological contexts to classify and discuss these organisms formally. It is not used in everyday conversation.
