They argued in a review paper... that a spider’s web is at least an adjustable part of its sensory apparatus, and at most an extension of the spider’s cognitive system.
...
This would make the web a model example of extended cognition, an idea first proposed by the philosophers Andy Clark and David Chalmers in 1998 to apply to human thought. In accounts of extended cognition, processes like checking a grocery list or rearranging Scrabble tiles in a tray are close enough to memory-retrieval or problem-solving tasks that happen entirely inside the brain that proponents argue they are actually part of a single, larger, “extended” mind.
One of the papers, a research article called 'Representation of different exact numbers of prey by a spider-eating predator' shows that spiders can differentiate between one, two and many.
...
In our experiments, we let Portia see a specific number of prey spiders in the range of 1–6, but the experimental apparatus was designed in such a way that Portia could access these spiders only by walking along a detour path that involved losing sight of the prey, and the detour route could be initiated only by first walking directly away from the prey. An important feature of these experiments is that they were based on using expectancy-violation methods. These methods are unconventional in studies on spiders and other arthropods, but they are often used in studies on the numerical aptitudes of primates, including human infants.
...
The results of this study can be characterised as P. Africana [predator spider] counting 1, 2, and many, which is similar to what has been observed with human infants.

In all honesty. Spiders fascinate and scare me at the same time. It's the unpredictable nature of them. When i find a spider in my house, I'll gently scoop them up in a paper towel. Then put them outside in the garden.

I almost dropped my phone when I saw that GIF.
As much as I tell myself I'm not afraid of spiders I'd probably kill that one, or if it escaped just burn the whole house down and call it a win.
I did. I get paid by the hour.

107 million...............I wonder who counted them all.
To keep blood and oxygen flowing throughout their bodies, most animals depend on a beating heart. But researchers reporting in Current Biology on July 10 have discovered that sea spiders use a strange alternative: they move blood and oxygen throughout most of their bodies by pumping their guts.
