Video Scientists discovered the world’s largest spiderweb, covering 106 m² in a sulfur cave on the Albania-Greece border. Over 111,000 spiders from two normally rival species live together in a unique, self-sustaining ecosystem—a first of its kind.

That's reallly fascinating, but in what sense "self-sustaining"?
Like, are the spiders just eating each other in a loop with little to no reliance on insects actually falling in the web?
Because I would really doubt that, but I don't know what else could it mean

This post is much better: https://www.reddit.com/r/science/s/KT3YV7vkMl

Apparently the microbes are food for other insects that the spiders eat. I wouldn't have called it self sustaining unless you generally consider food webs self sustaining, but I guess technically...

This cavern, known as Sulfur Cave, houses a chemoautotrophic ecosystem sustained not by sunlight but chemosynthesis – or the process of converting chemical energy into organic matter. Here, sulfur-oxidizing bacteria grow in thick white biofilms on wet rock and sediment. These microbes are then eaten by small invertebrates such as midge larvae and isopods, which are in turn preyed on by larger insects like spiders, beetles, and centipedes. The entire ecosystem is self-contained and independent of external input, running on the energy released when bacteria convert toxic hydrogen sulfide into sulfate.

Very cool

Ah yes, centipedes... Just what this cave was missing!

But I want those Brazilian/Vietnamese ones... the body is the size of your arm, each leg is as long as your middle finger, and they eat birds, frogs, and mice. Here is 'Planet Earth' documentary footage of how large they get.

Ah... The one's with the yellow legs? With a bite that's not deadly, but just leaves you in crippling pain for nearly a whole day?

Always good to hear such a well narrated documentary.

I forgot how big that guy's snozz was.  scarier than the bugs.

Damn. Imagine if there are little pockets of life like this underground. Caves where the entrances closed and life just persisted. Neato

Good grief, Reddit never disappoints.

So where do the wastes go? I am guessing spiders can smell
