Can an Octopus Count - Viewer Request

Үй жануарлары мен аңдар

We are always eager to test and prove the intelligence of our favorite masterminds, the octopus. We were therefore really excited to read the following request by one of our viewers:
“I remember reading an article about cuttlefish number sense in the Guardian a couple of years ago. I wonder if octopuses will prove to be as clever as the cuttlefish in the same experiment. Here is a link to the Guardian article:
www.theguardian.com/environme...
The Setup: Place two dividers on the two sides of the aquarium. Behind each divider, place a different number of crabs (e.g. 2 on the left versus 1 on the right, 4 on the right versus 3 on the left etc.) Make sure that the larger group of crabs is placed on a different side each time.
My hypothesis: I believe the octopus will choose to go after the larger group of crabs.”
Can an octopus count? Would the octopus score a better note than its fellow cephalopod, the cuttlefish, on this math test?

    Human: I'll randomize the side with the most crab so that the octopus doesn't see a pattern. Octopus: I'll randomize which trials I get correct so that the human continues the experiment and has to buy more crab.

    I was going to suggest where there are multiple crabs on offer in each end, perhaps the octopus chose to go with law of averages, "I'll definitely get one out of 5, rather than maybe miss both of 2". Same with 6/4. When it came to a 4/1, perhaps the single crab was going to be easier to concentrate on, and gain success. Keeping in mind, where the octopus seemed to select an end out of curiosity, near the end of the video experimenting ... It had already been taught that he wasn't going to be permitted any of the crabs at all - so it didn't really matter if he applied logic, instinct or "counting" of possibilities.

    It feels that way to me. I don't know how you would show that an organism can count. I think if you can should that they can distinguish between individuals, crabs in this case, that might show that they can count, Because if they can keep tract of multiple crabs and remember each one individually, I think it means that have to be able to count at least as high as the number of individual crabs they can remember. Does this make any sense?

    I was wondering the exact same thing. I think it would be interesting to see if the octopus can put objects in order of number. I’ve seen them do things I thought were impossible, so that doesn’t seem like much of a stretch. But how? Maybe first confirm that they know the concept of quantity and quality? Like give pegs of different colors and vary them by number. For example: 1 yellow peg, 2 green pegs, 3 red pegs, 4 blue pegs, and 5 purple pegs. Then give him/her a board with 25 holes in it. Have him/her put the pegs in the holes by color. Repeat with different objects, and vary the number of each color. 1 blue ball, 2 purple balls, etc, and give a plate with 25 depressions in it. Have him/her put them in rows by color and number. Then graduate to all the same color, but a different number of objects. Of course, you would have to up your ante in the reward category. 😁 I haven’t though too much about this, nor have I seen all your experiments. Maybe this overlaps with something you’ve already done, and if so, I apologize. I do love these creatures, though!❤️ EDIT: it just occurred to me that what I am describing is organization, not necessarily counting. 🤷🏻‍♀️

    Octopus are the natural predator of crabs. They will always scatter away from the sight of them, never attack. If there were a number of crabs surrounding an octopus at some point, it would be because the octopus was close to death. Once dead, the crabs would have done what they're instincts and habits tell them - clean up the ocean floor of any dead/decaying animals/flesh. Very similar to vultures hanging around for an injured bovine to finally die. So no, there will not have been a collaboration of crab minds, to plan to attack an octopus. It just doesn't happen like that.

    ​@kingsavageson4879 Actually, he doesn't "see" the glass, and doesn't recognise "they have nowhere to go". If you see in the first test, octy went for the line that he could see, in what we humans recognise as a join/corner. He went full pelt, and squashed himself in the corner, because he didn't recognise that the "line" was actually the edge of a see-through barrier going the width of the tank. (Proof of that is the fact that in the later tests, it started to stretch a tenticle out first, to see if it had been duped again.) When there are numbers like 3 vs 5, 5 vs 6.. he will go for the more targets - his brains tell him statistically, he's likely to catch at least one, with a higher concentration of targets, even when he knows he's going to be distracted by the others in the same chamber. When it's a test of 1 vs many... he recognises that even knowing there will likely be that invisible barrier again, he can concentrate on that single crab if he manages to "beat the barrier", without the distraction of many crabs on top of the task. They are incredible creatures, yes they logic out motion and statistical odds for the purpose of feeding. They're main downfall is the female when breeding. She will have one clutch, and starve herself caring for them. In all honesty, if nature hadn't dealt the octopus that harsh deal when multiplying - I believe we humans would be stuffed!

    Octopus : "More crabs there, I go eat them - but can't eat them because of the glass. _ New situation. More crabs on the other side, I go eat them - but can't again. _ A new one, and again can't eat the crabs where they are more. WTF, human ? _ New one. OK human, I understand, the game here is to be clever enough to go where there is less crabs but we can eat them. I go try this new strategy. Agh, can't eat them. Always this glass. _ New one. Let's try the second strategy another time, to be sure. I go for the less crabs. No, still can't eat them. So going for the less crabs isn't working either. _ New one. OK let's get back to normal strategy, at least if I succeed I will get many crabs. There are glass everywhere, so never mind, let's go to the more crabs place."

    Had the same thought. He went to the bigger number multiple times but failed to gain entry. So, he changes his strategy. Couldn't get through every time he picked the bigger number. So, he tried the smaller number. And by the end, he seems to be losing interest. Really interesting. Nothing conclusive, but it sure seems like it warrants study. I don't think I'd bet against that octopus in terms of his ability to figure things out.

    Wasn't this test just comparing the difference of less and more? Same test setup with a door that can be locked or unlocked between the glass partitions. The locks should use mechanics that cannot be seen to lock them (like magnets or some such). Keep the door high on the glass so octopus can always see the full number of crabs. Pick a number of crabs that will be rewarded. The number should be considered as something the octopus can easily kill and eat in one sitting. The number picked will remain the constant and will always be behind an unlocked door. The number of crabs behind the locked door can be anything not the constant number. If the octopus can count, then the subject should first attempt to open the door/gate to the crabs of the constant number picked. Then for the last test, we can confirm it is counting (after a good number of trainings) by leaving both gates open with the constant number and a number MORE than the constant and see if it will still head off to the picked constant number of crabs.

    I think maybe like the sea rays go after single crabs that have been separated from the group (or slower ones that have molted), the octopus may feel he has a better chance of just going after that one crab that's by itself. Interesting experiment though. Can octopuses recognize color, I thought most are actually colorblind (which is interesting because they are able to blend in with their environment)? If they can, perhaps try the tube experiment again (with the fish they can't see at the bottom), but put it in a specific colored tube. Then you can move the tube each time to see if he associates the fish being in a specific color one and keeps going for it.

    I think he didn't get rewarded for first few trys so he rethought the experiment and tried the single crab. Upon not getting rewarded that time, he again, ever hopeful, tried the single but curled up rather dejected upon running into the barrier. On the last try, he went for the larger number, even though they were fairly close in number. I think if he were given a reward for choosing either or everytime, it might be a better determination of whether he can see which is the greater or lessor dependant on reward choice.

    One of the problems with IQ tests is that subjects with a higher IQ than the test is calibrated for may consider more factors than anticipated. The octopus first went for the higher number of crabs the first several times, each time finding its path blocked, and then for the lower number. It's possible that it was checking if there was a correlation between number of crabs and the blockage, or had no specific theory, but simply decided to abandon the initial strategy for a more investigative approach. It also struck me that it might be guided by scent, sound or movement, which will often, but not necessarily, be determined by the number of crabs.

Repeat this scenario, but this time add another box with a different number of dots on it, but don't put any food under the new one. Maybe repeat this a couple of times, just to be sure they notice the pattern of the box with initial number of dots always having food. Then add another box with another number of dots, again without any food under it. Keep adding boxes with new numbers of dots, and see how consistently prioritize the box with the initial number of dots.

    I think what the octopus learned after many iterations, is that he cannot catch the crabs. Maybe he reasoned that if I go after one, the glass barrier will not be there and I can succeed.

    Maybe the octopus was choosing a side with more (or less) motion (or sound) from the crabs. Some crabs seemed much more active than others. Possibly, after being unable to get at the more numerous crabs, he tried the side with fewer crabs to see if he could get at them.

    In order to be sure that they are counting & not just looking, you should keep the difference between the groups with only 1 extra. Visually it’s much easier to spot a difference in group sizes when there’s 2 extra. To know they’re actually counting, you need to do like 6 & 7 or above. That way the groups of crabs will more easily appear even & if the octopus is consistently going to the larger group, then you know they can count. The only reason this doesn’t work with a food source as the counted groups is that the octopus may not be very hungry & therefore choose the smaller group

    He chose logically... chaos management by attempting to eliminate the outlier first thus leaving the remainder all at one end of the tank where they could be more easily managed. Very smart especially considering the rather large disparity. He factored into his decision extra variables that changed his choice. Possibly showing a self awareness of his own abilities and avoiding a situation akin to a human attempting to herd cats. Lol. A bird in the hand is worth ten in the bush.

    My idea is just to have two sides, one with say, 4 big red dots, and the other with 1 to 8 big red dots. The dots would be randomly organized (to counter pattern recognition) and only the side/door with 4 dots would lead to a reward. This would probably take several tries for an octopus to learn but I'm sure they can manage.

    As far as Counting goes I would try giving him a choice of 5 different treats each with a different number of dots under it. In the tank i would put a tray and several marbles all identical. Now at this point you while need to feed him with the number of marbles in the tray first that corresponds to what your feeding him for about three days on the fourth leave the marbles out of the tray and see if he starts to pick the food that he wants

    It seems like it never changed its mind or evaluated both options. It just always went for whichever side it saw first. You should do a control to see if this is the case by making both sides equal several times and seeing which it chooses when counting isn't a factor and see if it ever changes its mind or tends to look both ways before making a decision or if it does go after whichever option it sees first.

    You bet it was inconclusive! A) This test does not even address whether the Octopus can count. At best it only addresses whether it can distinguish' more' from 'fewer'. A counting test would involve testing whether it recognizes that a marble has been added to or taken from a group of identical marbles or transferred from one group to another. 2) Who knows what 'criterion' or 'criteria' entered into the octopus's 'decision'. The first time the critter went to the single crab instead of the many, I thought it might be because the lone crab was tight up against the corner of the wall and divider where experience has shown there is usually a skinny gap a tentacle can get through. (Snag the crab quickly, crush it, pull parts through to eat.) I suggest training the octopus by rewarding it for moving a marble from a pile to a box. Then reward it for transferring a marble to a specific box. Then reward it for transferring 5 and only 5 to a blue box, and 3 but only 3 to the yellow box, etc. Then change the number of marbles in the different boxes and reward the octopus for restoring the proper number to any of the boxes. If color is too hard for them to distinguish, the boxes could be various textures, sizes, or materials. This would have to be a series of videos given the duration you seem to prefer.

    I think he evaluates the situation each time under different prism. Many-more, they are many in both cases so lets increase the possibility of catching as many as possible, damage is a risk he will take in both cases. One-many, lets choose the safest meal, cause in many he might have some damage. One-two, they are few in both cases, so lets pic two to increase the possibility of catching one.

    Where was the incentive/reward for the octopus to choose the greater number of crabs? It would appear the experiment has desensitized the octopus from making any choice. Recommend replacing the crabs with similar looking objects (e.g. cubes), then place 1 crab in each partition. Each divider has a door. The door to the divider with the greater number of objects can be opened by the octopus, while the other door is locked. The doors must appear similar or the octopus could recognize a locked door from an unlocked door. The octopus must select the side with the greater number of like objects, open the door and receive the reward (e.g. crab snack). It will take several attempts to conditon the octopus to recognize the connection of the number of objects to getting access to the reward.

    It seems that, with multiple groups, Oct will opt for the larger group for the chance of a larger meal; perhaps because chances of injury are roughly the same and odds of eating are way better. In the case of one vs. many, the safer easier to target crab is sufficient.
