How octopuses battle each other | DIY Neuroscience, a TED series

Them's fighting words if you're an octopus, in that more than one octopus in a space often means a rumble. Neuroscientist Greg Gage and his colleagues analyze aggression by observing the fighting behavior of two-spotted octopuses or, if you prefer, octopodes.

    • elfspicer if we didn’t do this in order to learn from these animals, you wouldn’t appreciate them enough to care about their stress. This is done in appreciation for them.

    • +Woe Woe technically you could say the same about dog fighting yet that is largely seen as cruel. Just because we don’t bond with these animals doesn’t mean purposely putting them in stressful situations isn’t in human.

      I wish they would have gone more into detail on what we learn from watching them fight instead of look how cool this fight is

    • azigz I suppose that’s fair. I would say dog fighting isn’t quite on the same level of intellectual fighting as what these creatures here displayed. I would say that dog style fighting can be seen in other places but the fighting even just included in this video is unique enough to require further investigation to see if we can learn something deeper from it. We know a lot more about dogs than these very complicated octopuses so I feel it was necessary.

      I’m personally a supporter of this type of research because I feel the knowledge gained from making this happen in a proper setting outweighs the stress that the octopus will undergo. That’s something entirely up to perspective though so I understand if you feel otherwise.

    • Ahhh…yes…scientific discovery & education vs ‘they hurt my feelings & made me uncomfortable’
      ….ya’all realise that people eat these creatures? Fried, raw, & sometimes while still living?
      These guys are not killing them, or setting them free to be eaten by other larger creatures in the ocean…they just observed them.

    • There is no evolutionary advantage for the species in general if its members kill each other while establishing territory. This is an artificial scenario, they are put in a tank too small for both of their territories. In general, if two specimen are about equal in power they will fight, but only until weaker one senses he won’t win and runs away. Stronger one will chase the weaker off of his territory and then stop. Agression serves as a sort of repelling force in members of the same species or their groups. Because they repell each other in such a manner, each gets their own non-overlapping territory where each gets enough to eat. Aside from predation, they won’t attack species which occupy different ecological niches (as in ways of getting food) within their territory. This applies to most animals, though octopuses might have their own quirks. Also, this is a great example of convergent evolution!

  1. This is just a pointless bloodsport, these poor octopuses are suffering due to their cruel, torturous need for death!

    I’M SO TRIGGERED AND YOU SHOULD BE TOO!!!

  2. I am sorry but research is more important than your feelings about how this is unethical. If anything more research could prevent octopuses from suffering.

  3. WTF TED??? You put some octopuses to fight in order to watch how one kills the other. That’s it. Brilliant. No conclusion, nothing to learn, it isn’t even remotely close to neuroscience. This series makes zero sense.
