1. An octopus has three hearts. Two pump blood to the gills, and one to the body.
2. Its blood is blue because it contains a copper-based molecule called hemocyanin.
3. It has nine brains—one central brain and one small brain in each arm.
4. Octopuses have no bones, which allows them to squeeze through very small spaces.
5. They can change the color and texture of their skin to blend in with their surroundings.
6. An octopus can taste and touch using the suction cups on its arms.
