Transcript

Octopuses don't have one heart, or two, but three distinct hearts, each serving a vital and fascinating purpose in their complex biology.

Two hearts pump blood through their gills, where oxygen is absorbed, while the third, larger heart circulates that oxygenated blood to the rest of their body.

This setup is crucial because copper-based hemocyanin, their blood's oxygen carrier, struggles in cold, low-oxygen water, making efficient circulation essential.

The gills' hearts stop beating when an octopus swims, meaning the systemic heart works harder to ensure constant oxygen delivery, a unique adaptation for survival.
