How can someone have such a distain for spiders. I mean, look at this sweet little creature 😭🖤

Chinese hourglass spider - 里氏盤腹蛛 - Cyclocosmia ricketti

The Chinese hourglass spider is a fascinating species of arachnid, a very rare one at that ! Between the years 2000 and 2016 ONLY six of these spiders have been spotted in China, that we know of.

@hispaatra, @zick-the-fairy more on the awesome seal :D

Description

Cyclocosmia ricketti has a very distinctive disk on its abdomen which resembles an ancient coin, a seal, or even a grinding disc. The male Cyclocosmia ricketti are about 20.5 millimetres in length while the females of the species tend to be slightly bigger at around 25.83 to 30.0 millimetres in length. The largest known specimens can exceed 30 millimetres. The disk located on its abdomen typically has a radius of around 16 millimetres.

Extract from 'Zhu, Zhang & Zhang, 2006 : Rare spiders of the genus Cyclocosmia (Arachnida: Araneae: Ctenizidae) from tropical and subtropical China.' Raffles Bulletin of Zoology, vol. 54, No. 1, p. 119-124

According to Zhao Li, Director and Senior Biological Engineer of the Insect Museum of West China in Chengdu, Sichuan, Cyclocosmia ricketti is a nocturnal animal.

Predation behaviour

Cyclocosmia ricketti, like many other trapdoor spiders, dig burrows which are closed off by hatches in the ground. They do this instead of making webs, as they are not good at spinning silk, to catch their prey. They line their burrows with silk threads and mud. They use their disk to plug the opening of the burrow. When a small insect would step on its disk, Cyclocosmia ricketti will then purportedly shrink its abdomen to allow its prey to fall further into its burrow to be devoured. The disk also makes it difficult for its prey to escape from its grasp.

Cyclocosmia ricketti doesn't always use this method to hunt, as when its confronted with a non-threatening insect, Cyclocosmia ricketti will get out of its burrow and then directly grab it to eat it. This spider can also use the coin-shaped disk on its abdomen to protect itself from enemies by blocking the entrance to its burrow with it, and using it as a shield, a phenomenon called 'phragmosis'.

Distribution

Cyclocosmia ricketti are found in the Chinese provinces of Fujian, Zhejiang, and Sichuan. They are primarily found living in caves. The farthest north they are known to have been found is Sichuan, this is notable as it was previously believed that Cyclocosmia ricketti were not able to survive in places where the temperature could drop below 13 degrees Celsius. Winters in the province of Sichuan are known to get even colder.

just saw puss and boots heres my initial thoughts!

unanswered thoughts about where consciousness comes from, and the degrees with which consciousness exists, rooted in the perception of body and time

I was talking about editing a bunch of wikipedia pages to talk about native americans and farmer family friend was like

"yeah, it's like when we went to Turkey and we visited these historical museums, and the museums acted like the history of the country began when the Ottomans took over. The Hagia Sophia was built in what, 500 AD? And there are Roman ruins everywhere but the 'history' only begins in the 1400s. In this book I'm reading about the history of agriculture in Kentucky the author doesn't even discuss Native Americans before Europeans came. It's a huge oversight."

I've consciously tried to unlearn that shit so many times why does it STILL unlock little doors in my brain when I learn examples of how deeply arbitrary the boundaries of what we see as "history" are.

He also talked about how we have this idea of cave men being our ancestors because the things left by them in caves were more permanent, whereas the structures and things people built above ground would have decayed.

...I really do think about that a lot. How we have evidence of the civilizations that built things out of stone, while civilizations that used materials that biodegraded wouldn't have left as much evidence.

Come to think of it, some of the best known ancient civilizations did live in deserts. But they had contemporaries (like Punt, which we now know was in Ethiopia iirc...)

Farmer family friend also has been to Arizona (Might have been New Mexico? Idk.) and saw these Indigenous rock carvings he told me about that I never stopped thinking about. According to him, there's a rock face that has pictographs carved into it showing the steps of how to plant and harvest corn. "Very simple," he said, "like a tutorial."

And the crazy thing is. There's this nearby rock formation that casts a shadow on the rock face. And throughout the year, as the position of the sun changes, the shadow points to the step in the corn growing tutorial you're supposed to be doing at that time of year.

...I swear this guy has me come over just so he can have someone to talk to while he's doing mind numbing manual labor.
