!!install!! | Fish Physiology Notes

Fish are the most diverse group of vertebrates on Earth, inhabiting environments ranging from the crushing depths of the Mariana Trench to the hypoxic waters of the Amazon basin, and from freezing polar seas to hot springs. This incredible ecological diversity is underpinned by a fascinating array of physiological adaptations.

This is a physiological phenomenon unique to fish where a decrease in pH (acidification) dramatically reduces the oxygen-carrying capacity of hemoglobin. It is essential for forcing oxygen into the swim bladder against high pressures. 5.
