We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.

My (recently deceased) pet jumper really made me grasp that most animal life on Earth has a sense of self and desires beyond basic survival.
I mean, I knew these things as concepts before, some old study decades ago concluded that earthworms have characteristics of consciousness, if not full blown consciousness and self awareness, but there is a difference between reading about it, and experiencing it firsthand.
My spider absolutely loved sunsets. She had a particular spot in her enclosure that she would sit on, and watch the sunset every day. No reason for it beyond she liked to see it. Driven by purely biological needs, jumpers will either be hunting, hiding, or looking for a mate, but they exhibit "recreational" activities.
You can kind of communicate with a jumping spider too. They wiggle their chelicerae to communicate visually. I could put my fingers up near my mouth, and mimic the movements my spider would do. After a few repetitions, she would start to mimic me. I don't thing any grand concepts were conveyed, but I'm pretty sure she was recognizing mimicry from something that was not a spider.
They're really smart, and each one has their own personality, problem is, they don't live very long. Her last day was a hard day to say the least.
