Apparently octopus respond to molly in a similar way that humans do

Indeed!

I question the ethics of giving drugs to animals just to see what happens.

Imagine all the tracers he sees when he waves all eight tentacles in front of his eyes.

They can’t stand that woman either?

Just a note - I know it sounds weird but octupi are so weird and different than most any other organism on the planet that I wouldnt be surprised if they are some sort of alien lifeform.

At least the octopus is getting actual molly. :stuck_out_tongue:

I’m as much a For Science! guy as just about anyone, but maybe we should leave the octopus alone. They are are creepily smart, creepily adaptable and just plain creepy. If they ever find a way to use fire…

…Aannd the lyrics to “Octopus’s Garden” begin to make sense!

The scientists should watch out or the octopuses might learn how to shove 16 candles down the drain.

Of to play me some Sponge! (Hmm, I wonder what happens if you feed a sponge molly?)

Octopuses on Molly, spiders on LSD, mice taking cocaine, what will those crazy scientists think of next, Pandas on heroin?

It isn’t actually that surprising; the gene that binds MDMA and causes the brain to release serotonin, SLC6A4, is present in cephalopods, and while the cognitive structures of the octopus brain are completely different to that of vertebrates, the basic functions of neurotransmitters are the same across all animals. Given the evident behavioral complexity of octopuses, which in many species include complex signaling, conceptual problem solving, and nearly miraculous adaptivity to novel environments, it is hardly surprising for them to display affective behaviors which underly all cognition as we know it.

It is wrong, by the way to say “An octopus doesn’t have a cortex”; their neural structure is very different from vertebrates, being far more distributed, but there is still an organization to the octopus brain that includes the analogue to the cerebrum. It is difficult to speak about cephalopod neuroanatomy in general because within the class Cephalopoda there are a wide variety of brain structures evidencing a much greater evolutionary diversity of cephalopods compared to all vertebrates which is unsurprising because invertebrates predate vertebrates by a good 30 Myr to 40 Myr, and without the constraint of having a nervous system built around a notochord has a much wider field of play for morphological changes.

Here is a Science article that is more precise and less sensationalist than Gizmodo.

Octopuses (not octopi) and all cephalopods share a common genetic heritage with all other animals and indeed all life on Earth. That they are very different from vertebrates is simply a result of the divergence of evolutionary paths over the more than 500 Mya since vertebrates split off from all of the other invertebrates, the latter of which vastly outnumber those of us with spinal cords. See Squid Empire: The Rise and Fall of the Cephalopods for an evolutionary history (such as we have one) for cephalods, and Other Minds: The Octopus, the Sea, and the Deep Origins of Consciousness for speculation on how intelligence developed independently in cephalopods than it did (much later) for land vertebrates and particularly mammals.

Hmmm, this finding sort of supports the view held by some scientists that cleanerfish do not actually perform a service that is necessary to their clients beyond “feels good man”. I thought that was a silly idea when I heard it and still am not convinced that fish don’t need their teeth cleaned (I mean, aren’t humans supposed to floss?) but it seems less wacky now.

Hmmm… check the sponsors of this research to see if there’s a “Starkey Foundation” involved.

There is this short documentary on the effects of different drugs on spidets.

I’m outraged…

…that nobody took a video. Or if they did, that they didn’t release it.

The etymologically consistent plural is octopodes (oct-o-pode-ees) (note that I did not say it is necessarily correct just consistent with the Greek origin. Personally I like the sound of it)

It IS kind of fun :slight_smile:

The main thing though is “Octopi is definitely wrong in all cases and is never an option, and octopuses is perfectly acceptable in all cases including formal publications.” Along with “It’s not your teacher’s fault that they taught it wrong back then”.

The owner of a restaurant in Maine is blowing pot smoke onto lobsters before boiling them. Best quote from the article: “Whether or not hotboxing a lobster’s enclosure has any effect on its final moments on this earth is almost beside the point.”

I was reading about octopus brains the other day (inspired by this thread) and I came across the paragraph below which sounds credible due to specific detail, but I can’t find anywhere else that agrees with it:

http://theterramarproject.org/dc-archive/an-octopus-has-3-hearts-9-brains-and-blue-blood/
“It is tempting to use “octopi” as the plural of “octopus”, but DON’T DO IT. “Octopi” would be a proper Latin plural, but the word “octopus” has a Greek, rather than a Latin, root. The correct use is to use the word “octopus” to refer to one or several individuals of a single species; use the plural “octopuses” only when talking about multiple species.”

Is this just plain wrong, or is it maybe correct for marine biologists or something? Anyone know?

Everybody, regardless of species, gets the first hit free. After that…
