Why are the gill hearts white and our hearts red or purple?

The color difference between gill hearts in some marine organisms and the human heart is primarily due to the types of proteins involved in oxygen transport. Gill hearts may contain hemocyanin, which is copper-based and gives a blue or white appearance when oxygenated, while human hearts contain hemoglobin, an iron-based protein that appears red when oxygenated. This variation reflects adaptations to different environments and oxygen availability in blood.
