Why are they draining it in this way? Poor things.
It’s catch and release so they let them go afterwards where they found them. Horseshoe crab blood is an essential biomedical tool that’s saved countless lives.
What are some example uses for the blood? I’m fascinated.
Thanks for the reply too.
The blood contains a coagulent which clots in the presence of bacterial toxins. It is extracted and used to ensure that medical equipent and stuff such as vaccines are sterile and safe.
Here's a description of the bleeding process:
https://www.horseshoecrab.org/med/bestpractices.html
It's specifically non-fatal:
Bleeding horseshoe crabs to death is not an acceptable practice in the U.S.
The volume of blood taken is actually quite small, as most of the material in the collection jars is anticoagulant.
It may look uncomfortable to us humans, but keep in mind that horseshoe crabs are not human. What's normal for the spider is chaos for the fly. Granted, it would be kinda weird to be hoisted from your home by a giant ape and forced into a blood drive. It's done as gently as possible though.
Unfortunately the practice often results in death anyway. 30% die in the process.
It also has unforseen consequences in the food chain, so by all means we should look for alternatives.
Thankfully alternatives already exist .
Last I read synthetic LAL was nowhere near scaleable. Bleeding Crabs is very expensive.

Highest chance of survival/low stress
Edit: many do die still. I don’t want to say it’s safe, just safer
That's how blueberry is made Freeze some of this add some structure, let it set, then put it on trees

Obviously didn't read the meme. It's a blueberry milkshake. Everyone knows blood isn't that color.
So this is basically like a blood farm from vampires? Shit, still surprises me what an evil species we really are.
I kinda agree with you but when you think about it it's not that bad. They are released afterwards and we can use that blood to save countless people, like you and me.

A pint? That's nearly an arm-full!
People who know know that the crabs survive and are released back into the wild after their "donation"
Trivia of the day, horseshoe crab blood is blue because it is copper based instead of iron based like our blood
Real talk I'm fine with hurting crabs for our own means. Straight up.
Whoa! That's some Human Supremacist talk there.
Hell yeah. Whole point is to get the species off the rock, then out of the meat suit
Pretty sure I played a horror game with that concept once... SOMA?
I personally would like to become a conscious cloud of gas.
Or mammal supremacist. Or vertebrate supremacist. There are options
They're chelicerates though, not crustaceans. But then again, apparently everything evolves into crabs anyway
*CRAB PEOPLE. CRAB PEOPLE. *
everything evolves into crabs anyway
Does that mean I can become a crab too?

They're actually being fed the blue milk from Star Wars 8
That was green milk. Blue milk is from Episode IV.
It’s a simple, nearly instantaneous test that goes by the name of the LAL, or Limulus amebocyte lysate, test (after the species name of the crab, Limulus polyphemus). The LAL test replaced the rather horrifying prospect of possibly contaminated substances being tested on “large colonies of rabbits.” Pharma companies didn’t like the rabbit process, either, because it was slow and expensive.

This is the kind of shit you see right at the start of alien invasion type sci fi flicks.
Or in China on a Wednesday.
(I am being a little sarcastic, but traditional Chinese medicine can have some really shitty practices.)
The crabs are released afterwards, it doesn't kill them. Not saying it's a perfectly ethical situation, but at least it's not kill em en masse.
Just like tmnt
