   I recently learned that octopuses have three hearts! Two pump blood to the gills, where it picks up oxygen, while the third pumps it to the rest of the body. What’s even more surprising is that when they swim, the heart that delivers blood to the body actually stops beating, which is why they prefer to crawl rather than swim. That blew my mind! What about you? Have you learned anything cool lately?
