Next time you see a jumping spider, interact with it. Try to coax it to you with slow repetitive movements. Get close to it. Tap and wiggle your fingers gently. You'll likely find that they come to you. They seem to be curious on a different level than any other spider that I've interacted with (which are all garden-variety spiders in north america). They do tend to freak out if you try to take their picture with a m…

They're one of the only insects that show hunting behavior, as in pattern recognition and path planning [1], with brains so large that their esophagus has to go through it, to fit, with one of the largest brain to body rations of any animal. And, they dance [2]! Easily my favorite little critter. 1. https://roundglasssustain.com/species/portia-spiders 2. https://www.youtube.com/watch?v=5qkzwG2lLPc

Jumping spiders are quite common here in Singapore, and occasionally one will wander across my monitor while I'm working. If I move the mouse cursor in a circle around it, it will turn and follow the cursor. Amazing little things. Generally, I have an irrational fear of spiders, but for some reason these little guys get a pass from me. They're fascinating.

They are here in Scotland too, you’ll spot them mainly on windowsills. It’s one of the few creepy crawlies that actually seem to look directly at you.

Do checkout Blindsight because is great, but the Portia reference is actually from the sequel Echopraxia (a good book, but inferior to Blindsight; I mostly remember it for the Portia reference).

Now if we only engineered a retrovirus to uplift them into complex social structures and intelligence... https://a.co/d/85Wwwhi

Children of Time by Adrian Tchaikovsky is probably the best sci-fi I've read in the last 10 years. Its won the Arthur C Clarke award and recently the series (the other two books in the series are also great) won a Hugo

Also see Children of Time by Adrian Tchaikovsky for more smart-spider science fiction

I also immediately think of this book. Also the main character of the jumping spider species in the book is called Portia, likely refer to the same species in the article.

I had a pet jumper in my first apartment. He would follow me and my wife from room to room, wave at us, and sit by the sink when he was thirsty. We gave him water and called him Steve.

There's a reasonable pet trade for them. I never had the heart to put one in a box though. The most interesting interaction I had was watching one hunt a fly. The fly landed, and it crawled down on the side of the board the fly was on, out of sight. It emerged behind the fly, then snuck up on it, similar to how a cat does (move, pause, move, pause). Then, when it attacked, it didn't jump at the fly, but jumped up in…

They can take down prey much larger than themselves including small crickets and worms. They’re cool little creatures.

One of the craziest things to me when looking at a jumping spider is the unbelievable size and mass difference between us. An 80kg person is ~6,000,000x heavier than the average jumping spider. Whereas a blue whale is only like 2,000-3,000x heavier than that 80kg person (if I'm doing my math right). They are obviously tiny, but I wouldn't have imagined what titans we must be from their perspective.

A thought I've sometimes had is that if we had evolved to be as tiny as something like these spiders, but still at our current level of intelligence and society, chimps or elephants or whales would still be almost insurmountable threats to us even with today's level of technology. It'd take entire nations years of effort to build a gun or rocket that could even hurt something that much bigger than us.

Not clear, we might have ended up building industrial machines of roughly the same size. Elephants are soft compared to metal no matter how tiny the driver.

I forget who said this or exactly what they said, but someone has pointed out that the more research humans conduct the more we find that animals and even plants are more complex, more intelligent and more sophisticated than we thought. It is worth keeping this in mind the next time someone tells you a small creature (perhaps a crustacean) cannot feel or think or do something that would mean we ought to be less cruel…

That's great, but if I ever see a jumping spider in my house then I will not hesitate to murder it in cold blood.

Why?

This is really interesting research. It’s fascinating to hear about how these experiments are designed in the first place. If anyone is interested in this topic, I highly, highly recommend the book “Ways of Being” by James Bridle. [0] It covers such a diverse range of ideas about intelligence, including neural network–style intelligences, that I think pretty much everyone would find something of interest. One of the…

As soon as it mentioned intelligent spiders I was thinking "Children of Time" by Adrian Tchaikovsky https://www.goodreads.com/book/show/25499718-children-of-tim...

Oh, the anthropocentrism is strong here grasping at straws. It may also be just a genetically-imprinted fixed action pattern lacking strategic flexibility.

Scientists have been experimenting with portia spiders for a while and the surprising thing is specifically that a lot of their planning behavior does not seem to be hardwired. They can genuinely adopt to new preys and new environments and show learning behavior.
