How many hearts does an octopus have?
Answer
Three
Octopuses have three hearts: two branchial hearts pump blood through the gills, while a third systemic heart circulates oxygenated blood to the rest of the body. The systemic heart actually stops beating when the octopus swims, which is why they prefer crawling.
