Kobalt is Kobold

There are two kinds of crustaceans that are called "shrimp" that use concussive force via cavitation bubbles as a weapon.

These are Pistol Shrimp, a group of actual shrimp, and Mantis Shrimp, which are not actually shrimp but they are the ones you probably think of when you hear "murder shrimp" and "shrimp colors" (specifically the Peacock Mantis, bc there's a lot of species for both.)

I'm not annoying enough to grumble about the mantis being called a murder shrimp, because "murder stomatopod" is objectively a less fun combination of words.

HOWEVER!! People keep drawing mantis murder shrimp with pistol shrimp claws. They are not the same claws!! They are not used the same way!!! I will explain!!!!

Pistol shrimp: A number of shrimp species which have one big megachad claw and one dinky normal one.

The dactyl, or movable part of the large claw, is snapped shut with so much force that it shoots a cavitation bubble out with a very loud snap that can stun prey or scare off predators. It's very fucking cool.

As cool as that is, there is a reason that the mantis shrimp is what most people think of when they read "murder shrimp."

This is the Peacock Mantis Shrimp. Which is not a shrimp, but a stomatopod.

(In a lot of pictures it appears like they're staring intently at the camera. They probably are, because they are alarmingly intelligent.)

Note that it doesn't seem to have the big classic claws, and that's becaus it doesnt. Please stop drawing a shrimp claw on them. Their "claw" appendages are kept tucked up, praying mantis style.

These are a raptorial appendage that do have a sharp bit, but that sharp point has adapted to add support to the club end. They use the club to punch the shit out of things. They do punch so hard that they create a cavitation bubble, but the punch is the main deal.

If you look up a mantis shrimp puncher you may find this image, but they rarely if ever fold out fully past the punching part.

The second common mistake on mantis drawings is from mixing up two types of mantis shrimp. There are punchers, which includes the peacock mantis, and stabbers. You can guess what they do.

Fun fact! The peacock mantis is the largest puncher species, maxing out at 6-7 inches. Some of the stabber species, such as a zebra mantis can get 11 inches. This is because the peacock mantis is as big as it can get before it would shatter itself with the force of its punch!

This has been the marine biologist PSA.

Then we applied it to the "three" "parts" of the "world" (Europe, Asia and Africa).

Then upon discovering there were more than three bits a Science was airdropped in, so that it was now a large distinct contiguous landmass, a definition which worked perfectly for approximately one Australia, having found to their horror that it turned out Europe, Asia and Africa were connected.

i have a file or folder on my pc that i want to share with other people. let's call it gayshit.mp3

unfortunately gayshit.mp3 is 750mb and im not paying for discord nitro so i need another way to send it

i put it into qbittorrent and it makes a torrent file. this is essentially a very small file that points to gayshit.mp3 so other computers can find it. kinda like a treasure map

i send this tiny file to my friend, who loads it into qbittorrent. their computer takes a moment to find mine over the vast expanse of cyberspace and then (as long as my pc is running and the file is still where it should be), it gets copied from my hard drive to theirs

this is the cool part: if somebody else loads that tiny file, they can download it from both of us. if i'm offline but my friend is on, the third person can still get it. this also means that if two people have separate halves of the file, they can download the other half from each other. as long as some combination of people have the pieces between them, they can all have the whole thing.

crucially this does not require a server!!! you can just upload the file to a few people and as long as they keep it, it's still accessible. as long as somebody, somewhere is still connected, it's available forever. the only way it goes away is if everybody disconnects from it.
