Fish have a two-chambered heart, consisting of one atrium and one ventricle, which limits their ability to efficiently separate oxygenated and deoxygenated blood. This design means that all blood passes through the heart only once in a complete circuit, resulting in lower blood pressure and reduced oxygen delivery to tissues compared to the more complex three- or four-chambered hearts found in mammals and birds. While this is efficient for their aquatic environment, it constrains their overall metabolic capacity.

Does an Eel have two hearts?
Some fish do have a secondary heart located close to the tail end of their body. This is because fish have a single circulatory system which is inefficient in maintaining a high blood pressure from the heart to the gills to the body and back to the heart (unlike us who have a double circulatory system - blood is pumped to lungs, then back to heart and then to body before returning to the heart to repeat the process).
