Imagine a case of reverse evolution – an animal evolved water-breathing from an air-breathing ancestor. Design the gas transport cascade for such an imaginary vertebrate taxon, which breathes water, can support O2 consumption rate of at least 50 mlO2/kg/min. You do NOT need to concern yourself with HOW this beastly transformation occurred, but you DO need to make sure that EACH STEP of the O2 transport cascade works quantitatively. Show your calculations for each step of the cascade. Your numbers...
