What ETs Probably Look Like: Octopods

What will ETs look like once we finally meet them? Due to the number of water or ice covered worlds that probably exist, experts feel that aliens may appear more like intelligent octopuses than us.

To find out, [Michio] Kaku interviewed experts in exobiology, a field that studies what life might be like in distant worlds with different ecosystems. Based on his research, Kaku decided that intelligent alien life would have three necessary features:

  • The aliens, like humans, would have stereo vision, which allows eyes to compare images and track distance — a necessary feature in predators, who hunt and track their prey. “In all likelihood, intelligent aliens in space will have descended from predators that hunted for their food,” Kaku writes. “This does not necessarily mean that they will be aggressive, but it does mean that their ancestors long ago might have been predators. We may be well served to be cautious.”
  • The aliens would have some form of opposable thumbs or grasping appendages, necessary for hunting prey and creating tools (which they would have to do to be sophisticated enough to make contact).
  • They would also need to have language. “In order to hand down and accumulate essential information from generation to generation, some form of language is crucial,” Kaku writes.

In addition, Kaku theorizes that many alien civilizations will exist on ice-covered moons (like Jupiter’s moon Europa or Saturn’s moon Enceladus), where life would exist completely underwater. So how would an aquatic species become truly intelligent beings?

Kaku takes this thought experiment back to Earth. The one Earth-bound underwater animal that nearly fits all the above criteria — stereo vision, graspable appendages — is the octopus, he writes. The cephalopod, which has survived on Earth for at least 165 million years, only lacks language.

On a different planet, however, cephalopods could easily develop language — in fact, if conditions changed drastically on Earth, Kaku says it could even happen here, too.

“On a distant planet under different conditions, one can imagine that an octopus-like creature could develop a language of chirps and whistles so it could hunt in packs,” Kaku writes. “One could even imagine that at some point in the distant future, evolutionary pressures on Earth could force the octopus to develop intelligence. So an intelligent race of octopods is certainly a possibility.”
