Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.
Organisms that live in water need to obtain oxygen from the water. Oxygen dissolves in water but at a lower concentration than in the atmosphere. The atmosphere has roughly 21 percent oxygen. In water, the oxygen concentration is much smaller than that.

An anaerobic organism or anaerobe is any organism that does not require molecular oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment.

14 cze 2021 · Green blood? Science fiction or science fact? Overview. In this article you will discover that: many organisms need a protein to transport oxygen through the blood. these proteins are metalloproteins - they contain a transition metal ion. the transition metal ion must be able to be oxidised and reduced as it binds and releases oxygen.
