Usage Notes
  • The term is a specialized scientific term used in taxonomy (the science of classification). It is primarily used in academic, biological, and microbiological contexts.
  • This classification is not universally used in modern taxonomy, as protist classification is frequently revised. It represents a historical or alternative grouping for certain zooflagellates.
Examples
  • Scientific Description:
    • The Subclass Zoomastigina includes many parasitic species, such as Trypanosoma.
    • Organisms classified under Zoomastigina lack chromatophores, distinguishing them from photosynthetic flagellates.
Advanced Usage
  • The group is often contrasted with the (or similar groups), which contain flagellates with chloroplasts for photosynthesis.

  • Zoomastigophorea (n): A class-level name sometimes used synonymously or to encompass the zoomastigotes.
  • Zooflagellate (n): A common name for a non-photosynthetic, typically heterotrophic flagellate protozoan; a member of the .
