Finally, the gill serves as the kidney of the aquatic world. The primary nitrogenous waste of protein metabolism is ammonia, which is highly toxic. While terrestrial animals convert ammonia into less toxic urea or uric acid to save water, fish do not have that luxury.

This passive excretion is immediate and efficient, preventing the buildup of lethal toxins in the blood. : A direct citation of the company policy
