This article and the magazine seems to be well designed and put together. Nice!

Well said. I have the sharp-eyed HN mods to thank for introducing me to Knowable Magazine: the link I posted was to the article as syndicated in The Atlantic [1]; I'd not spotted the credit at the bottom of the page (usually I'd change to that, as long as the original wasn't paywalled).

I noticed about 10 mins after posting that the originating site in HN's list had changed from The Atlantic to Knowable, so I've been exploring its content, and like it.

Thanks to whichever mod is responsible for swapping the link. Also, the credit in The Atlantic was merely a link to Knowable's home page (which seems odd, really), so kudos to HN for thoroughness.

The portia genus are incredibly smart. I believe it is because its vision system, comparing to other spiders. Watch some videos on youtube and it chills how calculated the hunt is.

They seem to be in a class entirely unto themselves. There is something about the way they move and observe the world that gives them an apparent intellect beyond any other 'bug' I've seen. I used to keep bees and they are amazing in both their individual and collective ability, but it's hard to interact with them. Portia and other in the Salticidae family are almost like little dogs or something. They watch you, see…

Huh, interesting. That "Hunting of a spider" clip almost follows part of the intro sections in Children of Time 1-to-1. Feels like someone took 'inspiration' in someone else's homework. I wonder if it was BBC or Adrian Tchaikovsky who came first.

Oh, well. It is a really cool clip nonetheless.

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. The theory being she'd rather not attract predators with her corpse. A final step in sacrifice.

I too now try to redirect life forms to where they can live better. I used to seriously arachnophobic but nowadays I can manage grabbing a box or a long piece of paper to move insects around or outside if needs be.

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...

I get tired of reading from webpages like this.

Context switching is hard for the brain. Even in readabilty mode I get substracted by the image descriptions.

It's a pitty because it's a nice article.

I get rid of them, too. By gently escorting them out a window. And, like you, I apologize to them and wish them well.

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.

A tip if you are scared of spiders: Trap them in a glass, then slide some hard surface underneath. You can now move the spider (like out a window) while holding it trapped with the lid.

This has actually eliminated much of my arachnophobia, since I find myself studying the spider, safely confined inside the glass before letting it out. (This is actually one way they treat phobias clinically, a kind of desensitization exercise)
