“This animal has three hearts… and the reason is very strange! Octopuses have three hearts, and two of them stop every time they swim. That means they get extremely tired whenever they move. That’s why they prefer crawling over swimming. Even their blood is blue because of copper, not iron like humans. Nature is truly strange – there’s nothing like this creature!”
