Video insights
@bit_wonder's TikTok video "An Octopus Has 3 Hearts 🎧 Why does an octopus have 3 hearts? Two gill hearts push its blood through the gills, where it turns blue, and the main heart stops while it swims. The blue comes from copper hemocyanin, which carries oxygen instead of iron. It has about 500 million neurons, two-thirds of them in its 8 arms, so each arm explores on its own until the octopus crawls home.
