Octopuses are 100% Earth-born—but their mind-bending biology has sparked some of the wildest theories in science! Check out their bizarre traits: Alien-like DNA – Their genome is so unique it defies easy comparison with any other animal group. Shape-shifting masters – Color, texture, even form—they can mimic fish, coral, and more. Ocean geniuses – They solve puzzles, use tools, and escape aquariums like slippery Houdinis. Some fringe theories even claim octopuses might have extraterrestrial origins—maybe their ancestors arrived via panspermia, hitching a ride on icy comets. While there’s no scientific proof of alien origins, one thing is certain: Octopuses are the closest thing to an alien lifeform we’ve found on Earth. And they’re watching us… from the deep.
