One of my favorite animal facts is that octopuses have three hearts! Two of their hearts pump blood to the gills, where it gets oxygen, and the third heart pumps it to the rest of the body. Interestingly, when an octopus swims, the heart that delivers blood to the body actually stops beating, which is why they prefer to crawl rather than swim—it’s less tiring for them! What about you? Do you have a favorite animal fact?
