Usage Notes

• This term is used exclusively in scientific contexts, specifically in zoology, taxonomy, and evolutionary biology.

• It is typically used with a singular verb (e.g., "The family Peripatidae distributed in tropical regions.").

Examples

• Scientific Description:
  • The family Peripatidae is distinguished from its sister family, the Peripatopsidae, by specific reproductive and anatomical features.
