Octopus And Squid Evolution Is Officially Weirder Than We Could Have Ever Imagined
Just when we thought octopuses couldn't be any weirder, it turns out that they and their cephalopod brethren evolve differently from nearly every other organism on the planet. In a surprising twist, in April last year scientists discovered that octopuses…

Биологи дали осьминогам экстази и иследовали их реакцию: https://gizmodo.com/scientists-gave-mdma-to-octopuses-and-what-happened-was-1829191638
Осьминогам понравилось: они трогали друг друга, плавали с распростёртыми щупальцами, переворачивались и проявляли интерес к звукам и запахам.
After hanging out in a bath containing ecstasy, the animals moved to a chamber with three rooms to pick from: a central room, one containing a male octopus and another containing a toy. This is a setup frequently used in mice studies. Before MDMA, the octopuses avoided the male octopus. But after the MDMA bath, they spent more time with the other octopus. They also touched the other octopus in what seemed to be an exploratory, rather than aggressive, manner.
The scientists took this to mean that despite our vastly different brains, social behavior is built into the very molecules coded by our DNA.
При превышении определённой дозировки осьминоги «выпадали на измену»: у них сбивалось дыхание и они белели.

Scientists Gave MDMA to Octopuses—and What Happened Was Profound
When humans take the drug MDMA, versions of which are known as molly or ecstasy, they commonly feel very happy, extraverted, and particularly interested in physical touch. A group of scientists recently wondered whether this drug might have a similar effect…
