Fact of the Day: This animal has three hearts and blue blood
Octopuses possess a unique biological marvel: three hearts. Two branchial hearts pump blood through their gills, while a larger systemic heart distributes oxygenated blood. This complex system is crucial due to their copper-based blue blood, which is less efficient at carrying oxygen than human hemoglobin. Interestingly, the main heart stops when the octopus swims.
