Spiders can also get high on marijuana. It's true! They have the same thc-receptors in their brain as we do. It follows that they can get baked, enjoy an expanded consciousness and benefit from hallucinogenic insights just as we humans do. So get a spider high today.

Not only marijuana!

> “Jumping spiders are remarkably clever animals,” says visual ecologist Nathan Morehouse, who studies the spiders at the University of Cincinnati. “I always find it delightful when something like a humble jumping spider punctures our sense of biological superiority.”

I just find this notion bizarre, like we're all overblown ignoramuses strutting around thinking: 'I'm soooo much better than x pathetic creature!', and deserve to be taken down a peg or two. A really odd way to see things, most people I know are fascinated by nature.

As long as these spiders don't develop ICBMs I am sure a lot of people wont take thems seriously at all. It has always saddened me how many people just treat animals like lesser beings ready to be killed, tortured and controlled.

Reading about animal cruelty makes me sick - we should be more like guardians than overlords. I suppose this will never sit well with a majority of people, especially if they have other things to worry about...

Agreed, and then there are titles like the article's with a similar over-assuming sentiment. I always read them like eg "Spiders are much smarter than the writer of this piece thought"

I had a similar experience with a spider who had made an egg sack in a precarious spot along our back door that was definitely in hazard's way. I got a stick and a leaf and tried to detach and move her setup to a nearby spot that would be safer. She did not like that. At one point in the move, she got left behind and I ended up with just the egg sack to move. You could feel the panic and protective instinct in her mo…

>I watched her there for a while in her new location, and there is absolutely more than just instinct at play. One could also conclude the opposite. What we perceive as concious thought or emotion is just instinct.

At that point isn't it a bit a matter of semantics? I do agree with your point though. I think the way we think of instincts is far too simplistic and lacks an appreciation for how complex, adaptive, and context-aware instincts are

A couple years ago I had an experience with a spider that entirely changed my perspective on them and most insects, and now I make a conscious effort to help them as much as possible, instead of kill or even repel them. This particular spider kept running back and forth between my monitor and a window, and when it'd get to my monitor, it would wave its front legs at me. If I moved to the left, it would run across to…

There's something that gets to me anytime I see animals with their offsprings. A documentary about octopuses last moments in life, really shook me. It might be interpretation/anthropomorphism but anyway, apparently after laying eggs, the octo mom will breath out water (warmed by her body) around them. The process lasts a while and when she's exhausted she spends the remaining energy to swim as far as possible and die…

A lot of spiders have spread with humans and, depending on your environment, would probably not be able to survive outside. I usually ignore spiders I see in my house. I figure for every spider that's probably at least 3 less other bugs. One time we even let a daddy long legs care for its babies and watched as the hundred little eggs finally matured and hatched. Most of those babies probably died, but those that survived have probably helped keep the population of many other bugs down

I used to let spiders live freely in my house, until one time I wanted to go to bed at night and noticed dozens of black spots on the bed cover. I looked up and saw hundreds of tiny spider babies on the ceiling. From then on, whenever I see a spider in the house I get rid of it. Sorry...

most of those babies will probably die on their own anyways. If they do survive to adulthood it's only because they managed to kill some other bugs. So it'd be a net of less total bugs in your house if you just let them be

Mothers love is the primal force of the universe. Not just mammals (including humans, of course but read up on other vertebrates such as crocodiles and birds). Another poster mentions gastropods (octopus). You see it in plants. Trees preferentially share of resources with their offspring. Thanks for sharing an amazing story. I'm not surprised to see motherly love in spiders.

mother trees not only pass resources but also, what can only be described as, "chemical memories"

I used to have extreme arachnophobia, like strip-naked-run-screaming-if-I-found-a-spider-on-me level arachnophobia. A long time ago I was prescribed propranolol for PTSD by a psychiatrist specializing in trauma. I hadn't even mentioned my arachnophobia to her or any clinician I had seen at that point. It helped me a lot of social situations, but the effect was pretty subtle. Anyway, one day, I was hiking with friends…

People with arachnophobia should remember that 95% of the extant spiders are totally unable to pierce the human skin. Fangs too weak or short to reach blood capillaries and made any real damage, even if they would be poisonous doesn't matter. Those that coevolved with spider-eating monkeys are the problematic ones.

Yeah, as I mentioned in my post, I knew this rationally but it didn't help my phobia. If phobias could be rationalized away I suspect many if not most people who have them would overcome them fairly easily

This is a bit more elaborate behaviour than what I have observed from our (small) spiders here, but as a general rule, I don't do anything to spiders in my apartment as well. They keep their territory clean of other insects and do not get into my way, so I like keeping them. Unless the spider is really large, aggressive or poisonous, I do not get why so many people are afraid of them either. Perhaps that the Australi…

Just don’t eat them, you should be good
