And other drugs. All injectables are tested for pyrogens and endotoxins using the assay made from their blood.

They might want to evolve to have less important blood…

u/portabody Nov 25 '21

Basically, their blood is harvested for its ability to identify infections. If you can't efficiently identify infections in your system, you die. It's a pretty crucial property to forego. The only evolutionary direction out of this is extinction, unless we come up with alternatives.

Which there actually is. According to this link A synthetic alternative(s) have been available apparently since the 1990s. Unsurprisingly, industry wide acceptance has been slow. The EU only began accepting it July 2020. The US, with heavy ties to the blood harvesting industry, is still quite resistant to this change.

u/luckystar2011 Nov 25 '21 edited Nov 25 '21

If we keep harvesting, killing 10 - 30% and lowering reproduction levels of harvested crabs, they just might

Don't get me wrong, I support the harvesting, it's incredibly beneficial to everyone's health. I'm just saying there's risks and we might not have access to it at some point in the future

u/Cersad Nov 25 '21

Paradoxically, I've heard reports that their value actually motivates conservation efforts to protect these crabs. While drawing blood does have a cost in their population, the conservation efforts may help offset that.

u/mysterybiscuit Nov 25 '21

Is this like a sort of cobra effect? You tell people you pay €100 for a cobra head, so people start farming cobras.

Of course, with the cobras in India, that went horribly wrong when the authorities found out and made them worthless, so everybody released their cobras into the wild.

I don't think we've had a horseshoe crab disaster movie yet, but if any director wants to make that, 10%.

u/black_rose_ Nov 26 '21

There's a great radio Lab about horseshoe crabs their evolution and their blood and how that relates to modern sterilization of medical equipment and conservation efforts

https://www.wnycstudios.org/podcasts/radiolab/articles/baby-blue-blood-drive

Before their blood was discovered to be useful, people would catch them en masse and grind them up to use as fertilizer without any care for their conservation

2

u/starmartyr Nov 25 '21

There's a theory that the best way to preserve an endangered species is if we start eating it. If an animal becomes popular to eat, someone will be incentivized to start farming it.

2

u/Kumquats_indeed Nov 25 '21

Might not apply to all animals, but that's how its gone with alligators in the US. They don't breed well in captivity, so to "farm" them you have to have protected breeding grounds for wild gators, and then the eggs are gathered and hatched in captivity. Farming gators for their skin and meat has actually been beneficial to them and their habitat.

1

u/crisprcas32 Nov 26 '21

Yeah, super beneficial to the ones that get eaten, most of all

u/muck2 Nov 26 '21

That's why aquaculture exists. Starmartyr wasn't wrong. It's just that land animals are way easier to protect than marine animals. Not only are they actually accessible; also, the high seas are international waters and unless all countries agree to protect marine life the efforts of the few are in vain.

u/crayphor Nov 25 '21

I think, so long as they are not selected by quality of blood, any mutations leading to decreased blood quality will not propagate and lead to evolution.

u/RuneanPrincess Nov 25 '21

They don't kill the crabs iirc. Illegal poachers are the biggest issue.

u/Black_Moons Nov 25 '21

IIRC a study on them found they had a 30% 1 year morality rate from having blood harvested. they don't kill them, but the stress from losing blood greatly lowers survival.

u/tekky101 Nov 25 '21

I may be misremembering this but I'm too sick with covid-19 right know to confirm it. I recall the blood is for diagnostic tests, not vaccines. And it's so important and not reproducible by technology that horseshoe crab blood draws are very tightly controlled/regulated to be sure they don't harm them by taking too much too frequently.

2

u/portabody Nov 25 '21

So it's a step up from draining horseshoe crab's bloods entirely, but unfortunately it's still quite detrimental. While they're dropped back into the ocean still alive, it heavily influences their ability to function, moving to and from shallow waters, and drastically effects them during spawning seasons.

link

The bleeding process appears to make the bled animals more lethargic,
slower, and less likely to follow the tides like their counterparts do.

“The changes we observed in activity levels, movement velocity, and expression of tidal rhythms may interfere with daily L. polyphemusactivities, which would be particularly pronounced during the spawning season,” they write. “Spawning necessitates several energetically costly trips to the intertidal zone; larger females tend to make more excursions to the intertidal zone, often making multiple trips within the same week. An activity deficit, such as that caused by biomedical bleeding, may influence either the number of those trips or their timing. In the case of the latter, females may delay spawning activitywhile they are recuperating, and this could reduce their spawningoutput.”

u/tekky101 Nov 25 '21

At no time did I imply it was good for the horseshoe crabs. There's a crap ton of awful things that people do to exploit animals. I'd argue this is less awful than most of those things.

1

u/portabody Nov 26 '21

And it's so important and not reproducible by technology that horseshoe crab blood draws are very tightly controlled/regulated to be sure they don't harm them by taking too much too frequently.

I'm just providing a source that argues this.

And yes it is better than death but when controlled bleeding also effects reproduction rates? It's still detrimental to the species' survival, which makes bleeding harmful in my book.

u/WhitheredOldTree Nov 25 '21

Sorry about your sickness and hope you get well soon, but thats why I said it's important in the production of vaccines. Someone commented a little of how they go about this, earlier. But yes, they are very regulated. They catch them on one coast and release them on the opposite coast to ensure they don't catch the same ones.

1

u/tekky101 Nov 25 '21

Thank you. Also thank you for pointing out that I misunderstood the scope of your phrase "used in the production of vaccines." :)

u/black_rose_ Nov 26 '21

The blood is used to detect if there is contamination in items that need to be sterile for medical use

1

u/[deleted] Nov 25 '21

And they are starting to extinct for that.

3

u/WhitheredOldTree Nov 25 '21

Actually its because people are also harvesting them for food, bait and other things, too, but yeah. Sadly, it doesn't help on top of those. They're now considered "vulnerable to extinction", so close to being on the endangered list.

Oh man, I have mixed feelings about this. On one hand, they're doing this to save lives and they release the crabs when they're done. But on the other hand, that's pretty shitty for the crabs and a portion of them don't survive the process. I'm sadder now knowing that this is a thing.

20

u/OdrOdrOdrOdrO Nov 25 '21

Human life is more important than crab life, and I'm not exaggerating when I say those blue agar plates they use to detect coliforms save millions of lives each year. Besides, they are an extremely primitive species. Their experience of pain is probably no more than an increased drive escape.

u/iamwizzerd Nov 25 '21

Only more important to humans. I'm sure the crab would say his life is more important

You may have mixed feelings about the next piece of info, there is already an artificial alternative to the crab blood, and it's been around for some time. I think it was only recently approved for use in Europe though.

It definitely does suck for the crabs but humans will unfortunately do whatever they have to too extend living it would be better if they could save them maybe rehab the crabs before release

u/theswordofdoubt Nov 25 '21

humans will unfortunately do whatever they have to too extend living

It's not like this is a unique trait for humans. Any living being does whatever it can to survive longer. That's practically the entire definition of living. If our positions were swapped, horseshoe crabs would be harvesting us just as much.

u/bartonski Nov 26 '21

I would like to point out something that the article says, but is not nearly explicit about: An extract of the blood sell for $60K/gallon. The product is called LAL (Limulus Amebocite Lysate); it's a clotting factor that gells when it comes in contact with the cell walls of gram negative bacteria -- also known as endotoxins.

The protein is found inside amebocites, which are amoeba like blood cells, this is separated from most of the blood in a centrifuge. Most of the blood volume is poured off. Distilled water is added to the amebocites, which causes the cell walls to burst -- i.e. 'lyse' (hence 'lysate').

Horseshoe Crabs have blue colored blood. Their blood is the closest to human blood in composition, with the only difference being hemocyanin to carry blood instead of hemoglobin. They are also used to test vaccines and their effects on humans without testing actual humans.

Except Lamarckian evolution doesn't happen. It isn't the case that the horse reaches really, really high up for apples on the tree and then his offspring have long necks. No one gets to choose a biological adaptation. It's not a matter of character or what anyone wants.
