WTF Fun Fact 12606 – Octopuses Getting Punchy

Octopuses are incredibly smart. In fact, we’re only just now starting to learn how their complex brains work.

Take this factoid, for example. Octopuses need so much intellectual stimulation that those in captivity require games and puzzles to keep them from eating off their own arms out of boredom!

But did you know octopuses also have a bit of a mean streak?

Researchers have observed the creatures punching fish in the past – everything from a warning “boop” to a “curl up and let ’em have it” punch. Punching is pretty rare, but in many cases, the researchers could ascertain some reason for the punch. Usually, the octopus was trying to keep the fish from spoiling its meal.

However, sometimes octopuses punch fish for revenge. And revenge isn’t something we usually think of as relevant to underwater creatures.

More recently, Eduardo Sampaio recorded the underwater action. He also concluded that some octopuses seem to haul off and punch their hunting partners for no reason at all. That is, they don’t stand to benefit in any way from punching the fish.

Sampaio even posted a video to Twitter to illustrate the punching action:

So, apparently, “throwing a sucker punch” is yet another factoid we can add to humanity’s ever-growing list of things we know about but can’t explain when it comes to octopuses.
