just learned something super cool today! did you know that an octopus has THREE hearts? 😲 two of them pump blood to the gills, while the third one pumps it to the rest of the body. isn't that wild? 🐙 also, their blood is blue because it's copper-based instead of iron-based like ours. nature is totally mind-blowing sometimes! 🌊✨
