Did You Know Octopus Has 3 Hearts… And BLUE Blood? 🐙

[0:00]Hey. Did you know this creature has three hearts and blood that isn't even red? Watch closely. The giant Pacific octopus. While your blood runs on iron, it runs on copper. That's what makes it blue. Three hearts keep it alive. But when it swims, one heart actually stops. And when danger gets close, not blood, but a cloud of ink, and it disappears.
