[Answer] Which animal has three hearts?

We have looked all around the web to find the most relevant answer to your query: 


Which animal has three hearts?


  • Octopus:The Octopus is one of the most fascinating animals on the planet. These marine cephalopods developed differently from their invertebrate cousins. An octopus has blue blood because of the presence of hemocyanin, a protein rich in copper. This blood protein helps it use oxygen efficiently in the cold ocean environments. Because their bodies are made up of mostly muscles, octopuses have three hearts. Two of the hearts, the smaller ones, pump blood to the gills. The largest heart is responsible for circulating blood in the rest of the body. Source: NeedforScience.com
