    • The turtle is an air-breathing reptile that can hold its breath for a long time underwater.
    • The study focused on the lungs of air-breathing fish.
Advanced Usage
  • Used primarily in biological, zoological, and paleontological contexts to classify organisms based on their respiratory methods.
  • Often contrasts with terms like "water-breathing" or "gill-breathing."
    • The transition from water-breathing to air-breathing was a key step in vertebrate evolution.
Variants and Related Words
  • Air-breather (noun): An organism that breathes air.
    • Mammals are obligate air-breathers.
Synonyms
  • Pulmonary: Relating to the lungs (often used in a similar technical context).
