Octopuses Have 3 Hearts – and One Stops When They Swim! #bytesizedfacts #didyouknow #octopusfacts

🧠🐙 Did you know that octopuses have three hearts—and one of them actually stops beating when they swim? It sounds like science fiction, but it’s true! In this 60-second short, we dive into one of the strangest biological facts from the deep sea.

Octopuses are some of the most fascinating creatures on Earth. Not only are they incredibly intelligent (some say as smart as dogs!), but they also have blue blood, suction-cup-lined arms that can move independently, and a nervous system that’s completely unlike ours. But perhaps the weirdest fact of all is how their three-heart system works—and how it changes based on whether they're crawling or swimming.

Here’s how it works:
🫀 Two hearts pump blood to the gills to get oxygen.
🫀 One heart pumps oxygenated blood to the rest of the body.
But when they swim? That main heart shuts down. That’s right—they literally give their heart a break mid-motion. That’s why octopuses prefer crawling along the ocean floor—swimming is actually exhausting for them!
