The planet Earth houses a wide variety of animals and creatures. And, there are a lot of things about these amazing animals that humankind knows very little of. One such animal has three hearts and nine brains. Can you guess which creature we are talking about here? If not, you do not have to rack your brains too hard because we have the answer for you. It is an octopus. Yes, the multi-tentacled creature that has always intrigued us has three hearts and nine hearts. Read on to know why.

Another interesting fact about an octopus is that its blood is blue in colour. We have red blood because it contains an iron-based protein called hemoglobin. But the octopus has a copper-based protein in its body called hemocyanin, due to which the blood turns blue. Hemocyanin does not blend with oxygen as easily as hemoglobin does. Because of this, two hearts pump blood through the gills, which get oxygen and blood, and the third heart pumps it throughout the body.
