Over the last 4 months or so, I've been learning quite a bit about spiders, like the fact that jumping spiders can count.

Researchers would set the spider up on an elevated platform where they could see like 3 flies or something, but to get them, they'd have to plan a route through a bit that will blind them briefly. If they come out of the blind and see that the flies are not 3 anymore, they'll hesitate and watch for a bit, as if they're surprised or suddenly uncertain.

They're also capable of learning. Orb weavers rebuild their webs every night, and they build it differently depending on what prey they expect to find. But not only that, if a prey goes absent, but is reintroduced later, they're quicker to resume a web that worked for that kind before.

It's important not to humanize too much; you may make assumptions that will get you in trouble. But, I do think there's a little consciousness in that small body.
