Oxygen & Growth

Breathing under water is challenging. How does the oxygen uptake of cold-blooded, aquatic animals change as they grow?

Both the capacity for oxygen uptake and the oxygen requirements of animals changes with body size. To provide a better understanding of changes in respiratory challenges during growth, this animation explains: 1) how body size affects oxygen supply and demand via changes in surface area to volume ratios and 2) how viscosity effects respiration.
