Standard Metabolic Rate (SMR) of round stingrays was measured using the mass-specific oxygen consumption rate (MO2, mgO2 kg1 h1) from static respirometry trials. These animals, of which there are approximately 530 known species, are the oddballs of the reef ecosystem. Learn more about the Pacific cownose ray and the science behind stingray barbs below!
