I've run into electrical rooms during fire inspections that were almost as bad. Those were mostly Black Widows, though.

They must be surviving by eating their babies... How sick is that?

55,000 potential mates in pitch blackness. Kinda a reminds me of my days in bars long ago.

[Redcitizen]

Nope. Not me. 😬

Frodo, suspended in the web, is at a loss until he hears the voice of Gollum, who is watching, gloating, nearby.

Gollum: (In a sing-song voice) Naughty little fly, why does it cry? Caught in a web, soon you’ll be dead!

Who was the poor schlemiel whose job it was to COUNT them (over 110,000!)

Looks like some of the cobweb spiders around here if I don’t clean them out pretty regularly.

111,000 spiders thriving in what appears to be the world's biggest spiderweb,

I have to imagine that the only way a colony of 110,000 spiders survives in such close proximity is to cannibalize each other.

Note to self #1: Do not explore the Sulfur Cave.

Note to self #2: If you insist on exploring the Sulfur Cave, bring a flamethrower.

Nuke it from orbit. It’s the only way to be sure.

Comedian Nate Bargatze has a routine about that. He says that most scientific pronouncements go unchallenged. So scientists can make up any number they want.

There were so many, but no one could find Charlotte...

I Believe it.

I mean...Who’s gonna do a RECOUNT?

Not Me, I’ll tell you that. 🕷🕸🕷🕸🕷 Eyew!
