The octopus has a closed circulatory system, and blood remains in the blood vessels. The octopus has three hearts. A whole-body heart that circulates blood around the body and two gill hearts that pump blood to each of the two gills. The whole body heart is inactive when the animal is swimming, so it prefers to crawl tired quickly.

If you lose one and the main heart, the octopus can pump blood and oxygen to one heart, but not the rest of the body. Brachiopods have black blood.
