A Brain in Eight Pieces

Most of an octopus's neurons aren't in its head. Roughly two-thirds live in its arms, which means each arm can taste, touch, and decide more or less on its own. Imagine your hand solving a problem before you've finished thinking about it.

"The octopus is the closest we'll come to meeting an intelligent alien." โ€” every marine biologist at a dinner party

Things octopuses are alarmingly good at

  • Opening childproof jars (from the inside)
  • Recognizing individual human faces
  • Holding what can only be described as a grudge

A short, true-ish timeline

  1. Octopus is placed in a tank with a screw-top jar.
  2. Octopus opens jar in under two minutes.
  3. Octopus stares at researcher.
  4. Octopus is found three tanks over the next morning.

You can read more about cephalopod intelligence over at the Monterey Bay Aquarium.

For the developers in the room

If an octopus ran your build, it would probably look like:

while (!escaped) { tryEveryGap(); }

That's the whole strategy. It just keeps trying every gap until one works.


This is a test post. No octopuses, jars, or production blogs were harmed.
