Transcript

Octopuses don't have one heart like us; they have three. Two pump blood through their gills, and a third circulates it to the rest of their body.

This setup allows them to maintain high oxygen levels, especially important for moving through cold, deep ocean waters where oxygen is scarce.

Their blood isn't red, it's blue, due to a copper-rich protein called hemocyanin. This protein is far more efficient at transporting oxygen in extreme cold.

Human hemoglobin, on the other hand, struggles in the deep sea. An octopus would literally suffocate with our red blood, showcasing its unique adaptation.
