What Ecstasy Does To Octopuses (theatlantic.com)

Gul Dolen, a neuroscientist at the Johns Hopkins School of Medicine who studies how the cells and chemicals in animal brains influence animals' social lives, gave ecstasy to octopuses and recorded her observations. The study, published in the journal Current Biology, suggests that the psychoactive drug that can make people feel extra loving toward others also has the same effect on octopuses. An anonymous reader shares the report from The Atlantic: [Dolen] and her colleague Eric Edsinger put five Californian two-spot octopuses individually into the middle of three connected chambers and gave them free rein to explore. One of the adjacent chambers housed a second octopus, confined inside an overturned plastic basket. The other contained an unfamiliar object, such as a plastic flower or a Chewbacca figurine. Dolen and Edsinger measured how long the main animal spent in the company of its peer, and how long with the random toy. The free-moving individuals thoroughly explored the chambers, and from their movements, Dolen realized that individuals of any sex gravitate toward females, but avoid males. Next, she dosed the animals with ecstasy. Again, there's no precedent for this, but researchers often anesthetize octopuses by dunking them in ethanol -- a humane procedure with no lasting side effects. So Dolen and Edsinger submerged their octopuses in an MDMA solution, allowing them to absorb the drug through their gills. At first they used too high a dose, and the animals "freaked out and did all these color changes," Dolen says. But once the team found a more suitable dose, the animals behaved more calmly -- and more sociably. "With ecstasy in their system, the five octopuses spent far more time in the company of the same trapped male they once shunned," the report continues. "Even without a stopwatch, the change was obvious. Before the drug, they explored the chamber with the other octopus very tentatively."

"They mashed themselves against one wall, very slowly extended one arm, touched the [other animal], and went back to the other side," Dolen says. "But when they had MDMA, they had this very relaxed posture. They floated around, they wrapped their arms around the chamber, and they interacted with the other octopus in a much more fluid and generous way. They even exposed their [underside], where their mouth is, which is not something octopuses usually do."

    The real question... does ecstasy make octopuses feel extra loving toward researchers? Just think of the possibilities.

  5. It's actually kind of a big deal by rsilvergun · · Score: 3, Insightful

    philosophically anyway. It lends credence to the idea that social behaviors can be traced back to certain chemical responses. The reason that matters is stuff like religion and the origin of morality. There's a pretty big debate on, for example, whether you can have morality without God. This is a notch on the atheist's side since it implies socializing might have a generalized chemical factor to it.

      Where is that !? At your local evangelical church or mosque? Even there, it would only be among the dumber, more zealous members.

      I mean, not only is it obviously true, but it even turns out that societies share the same moral values, even when individual members have different or no religions.
      i.e. religion does not shape moral values, but the opposite occurs.

  7. Correlation is not causation by uvajed_ekil · · Score: 4, Insightful

    We need to be careful here not to infer that the rolling subject octopuses are spending more time with the contained male because they want to interact socially. We don't know how sober octopuses think, so it is terribly wrong to assume that high ones are not just out of their minds with no idea what they are really doing. We do know what different dosages of MDMA tend to do to humans, though there is still variability there, while we know nothing about the octopus MDMA response curve. It appears that MDMA does make them behave abnormally but it is impossible thus far to draw any conclusions about octopus motivations, and probably wrong to apply human concepts of mood and socialization. The octopuses exposing their undersides and doing flips and whatnot might indicate that they've lost their shit, more so than that they feel all warm and fuzzy and want to cuddle.

  8. Jerome Lettvin knew by Swave+An+deBwoner · · Score: 5, Interesting

    https://en.wikipedia.org/wiki/Jerome_Lettvin

    While working in the Marine Zoological Station in Naples, Letttvin had a 30-foot-long (9.1 m) room in which octopus holding tanks were kept, with fine mesh metal screens to keep them from escaping. One tank, at the far end, held his youngest son Jonathan's pet octopus, known as Juvenile Delinquent or JD.[11][not in citation given] One day he teased JD with a stick. The next morning, he and his son came to the door, and noticed a puddle. Fearing that the tanks had broken, Lettvin opened the door, and was greeted by a blast of water in his face (but not his son's face). From across the room, and through the screen, JD had perfect aim, after which he jetted to the bottom of the tank, inked it up, and hid for the rest of the day. Still confused about the water under the door, Lettvin looked at the back of the door and saw a spot of water at the height of his face. JD had been practicing for revenge. From this and other experiences, Lettvin concluded that octopodes are highly intelligent, and from that time on he never ate octopus again.[citation needed]

    > is that Exodus and Moses are Canon

    *facepalm*

    The Torah is NOT a history book. Take Genesis: It has the lie of omission about Adam's first wife, has contradictory creation stories (Man is created _after_ the animals in chapter 1, but _before_ the animals in chapter 2), has the nonsense of day & night existing BEFORE the sun was made, chapter 4:4 shows that there were humans BEFORE Adam, etc. In Exodus we find nine of the ten commandments come directly out of the Egyptian Book of the Dead. The only ones treating Moses as canon are those ignorant of history.

    It is obvious you've never read it, let alone understand the allegory of it.

    e.g. Why is Day 2 of the creation is the ONLY day that doesn't say "It was good."
