What color is the octopus blood? How many hearts does it have?

- Octopus blood is blue because it contains a copper-rich protein called hemocyanin that carries oxygen in the blood. In contrast, human blood is red in color because it contains iron-rich hemoglobin.
- An octopus has three hearts. The two hearts pump blood through the gills, where oxygen is absorbed from the water. A third heart pumps deoxygenated blood to the rest of the body. This unique circulatory system enables octopuses to efficiently extract oxygen from the water, which is necessary for survival in their marine environment.
