Why does the blood do? Does it clot at any contamination or something?
Yay, milkshakes!

It’s used for the detection of bacterial endotoxins. We it’s version of white blood cells for it.

That’s the blue mana they need to activate their ability and untap themselves!

And surprise, this is most prevalent in the USA.

I mean yeah but all species of horseshoe crabs only live in three places on earth. I can only speak for limulus polyphemus, which only lives on the East Coast of the US (from the Gulf of Mexico to Maine), but I’m not sure how much other species are even bled. Actually to be honest I’m not even sure they have the same extra cellular protein that is collected from the blood…. Possibly should look into that. Maybe I could get some funding to travel to Indonesia for blood samples.

Five companies along the East Coast — with operations in South Carolina, New Jersey, Massachusetts, Virginia and Maryland — drained over 700,000 crabs in 2021. That’s more than any other year since officials started keeping track in 2004.

That’s far more liquid than I expected them to contain. I also expected them to be left alive, not drained dry. Wouldn’t it be more economical to feed them in a large tank for a few weeks, rather than killing them outright? I feel like fish food, by mass, costs 1/10th or less of live horseshoe crabs.
LostGhost@piefed.social 20 hours ago
That is not all from one crab and they generally try not to kill the crabs. There is some debate on how many actually die with the companies bleeding them claiming almost none and some other people saying up to 60%, so the truth is probably in the middle in there.
As far as keeping them alive in a tank it’s not to hard. I have been working with them for a few years now and we have some at work. They mostly eat shrimp here not fish food. We have raised them from eggs. One of the big issues with raising them in captivity for the long term is we still are not sure how large chunks of their lifecycle works. For example while we have some ideas we do not have definitive proof of how they develop their sex. We think there are genetic factors but if I remember correctly there was a paper published a year or so ago that said there might be a temperature Factor, somewhat like turtles.
Fun fact, they will not eat micro plastics. We had an undergrad doing an experiment to see if they would eat micro plastics and how it would pass through their system but we were never able to get them to even ingest any.

You said they eat shrimp. The micro-nanoplastics are in them.
sudoMakeUser@sh.itjust.works 21 hours ago
This process is generally not lethal. They are returned to nature once this process is completed, although some do die in the process. Also I’m no expert but those containers might be a collection of multiple crab’s worth of blood.
Not trying to defend or attack this process.

So they don’t get a blueberry fruit juice shake before they go back to their home?

You wouldn’t just need the fish food, you would have an aquarium large enough to keep them all alive and meet the legislative standards for wellbeing. That aquarium needs space, cleaners, inspectors, etc, which would drive up the cost considerably.
