Octopus Den Size Selection - VIEWER REQUEST

Үй жануарлары мен аңдар

Will our octopus choose the smallest den, the biggest den, or the one in between?
This experiment was requested by KZread user Jonas Kirk. Here is what Jonas wrote:
“The little octopus dens featured in your videos are simply amazing. They made me think of an experiment…
What would happen if you placed different sized dens in an octopus's tank? Would he show preference to one of the sizes?"
"Place 3 of the octopus dens we see in your videos into a tank. The dens should preferably be of different sizes. See which of the dens he'll choose and then run the same experiment with the same dens placed in different positions. This should hopefully give us an answer as to which sized den he or she prefers.
I bet that in the wild there are a number of factors that influence the octopus in selecting its den. But what would happen if the only difference was the size of the octopus den?”
We presented a medium-sized octopus with three different den sizes, a big one, an average one, and a smaller one.
Octopuses in the wild have been observed to choose dens small enough so that they can maintain contact with the walls with all of their arms. Also, dens are relatively small, and they have a maximum volume two to three times that of the octopus. The size of the octopus is believed to be in proportion to the size of the den.
We were therefore expecting the octopus to go for either the small or the average sized den.
We rotated the position of the dens twice to make sure that proximity to a den was not an influencing factor.
It was fascinating to watch our octopus investigating its options and making a clear decision.
We hope that you enjoy watching this experiment and that you will keep contributing to our research with all your wonderful ideas!

    experimental bias: the first time the octopus chose a den, he then kept a memory of it as 'safe' , plus it may have left a mucus/substance as a signal that he went there already. Therefore we cannot conclude that octopus prefers a bigger den. Repeat this experiment with different octopus, and wash the ball as the traces left by a previous octopus may attract, or repel, a different octopus.

    *@Octolab TV* Try to present even larger dens (if you have any?), until the octopus stops choosing the largest den, that's probably the most "right size" for the octopus? (or the opposite if the octopus consistently chooses the smallest den) Also, make sure the experiment den's haven't been in the water at all before, so they don't "smell familiar" or something like that, maybe even *use a totally unfamiliar: shape, color, material & texture,* then see what the octopus chooses. :)

    My edit involved correcting the spell check & structure. Seems a no-brainer to me. If looking for a living area, it's going to go for the largest square footage it can afford (or find). Maybe it just wants "Octo-Cave". A place "he" can watch his big screen, have his buds over for "Squids Gone Wild!" videos while enjoying kegs of squid ink and plates of Flounder Fritters & "Tuna Wings"** Or a place "she" would have her "Octopussies Only" room. A place where she can invite her friends over for a "craft night". They would try to make stuff from the litter that falls to the ocean floor, but Craft Night often translates into no crafting at all. It would involve pitchers of Marlin-ritas or Crustacean Cosmos and platters of shrimp kabobs, crab puffs and sea cucumber cake for dessert. Everyone would be in groups that would talk about males, how they could make their fins shinier and how painful & long spawning is (you'd get more of that if it was a Fry Shower). When things start to lag or 1 starts to cry, it's time for a pitcher of "Tuna-tinis" (good thing the hostess has 8 arms) and dancing to songs like, "Under the Sea" & "Barracuda" by "The Barnacles". I'm 60 yrs old and have always had a imagination. **Years ago there it was a slogan for a brand of tuna, "Chicken of the Sea". So, chicken wings, tuna wings.

    Picking the biggest one? Maybe he is compensating for his hectocotylus. Jokes aside, assuming this is the same octopus each time, is it possible that he can tell that it is the same den he may have chosen the first time so that he has become attached and will chose the same one each time? A test would be to take dens of the same size and shape, then switch them around and see if the octopus picks the same one each time.

Is that the sort of thought they might be capable of?
