It is not an anticoagulant, quite the opposite actually. The blood (limulus amoebocyte lysate) will coagulate at the slightest hint of gram-negative bacteria and their endotoxins.

It's most likely a defense mechanism against bacterial infections.

It's widely used in medicine to check for bacterial contamination of injectable pharmaceuticals.

Woah. Are horseshoe crabs like other crustaceans in that they eat pretty much anything including/mostly detritus?

If thats the case, than how would it be beneficial to have blood that coagulates so easily?

Wouldn't every meal lead to a crab version of a stroke?

[-] Mercival@lemm.ee 7 points 1 year ago

Horseshoe crabs are not crusteceans, they are early chelicerates.

They have an open circulatory system, where the blood (heamolymph) freely spills out of the arteries into surrounding tissues, so a small clot probably wouldn't cause issues. Think of it like a cyst, sometimes if an infection can't be removed by the immune system, your body will just enclose it in a capsule, so it can't spread.

Ahhh that makes sense. That's a pretty cool defense system

[-] MeanEYE@lemmy.world 4 points 1 year ago

They are not crabs nor crustaceans.

[-] Kedly@lemm.ee -5 points 1 year ago

Not a relevant time to be pedantic

[-] MeanEYE@lemmy.world 7 points 1 year ago

Well, he asked if they are like other crustaceans, so the answer is they are not crustaceans so no, they are not like others.

[-] Kedly@lemm.ee 7 points 1 year ago

Aww fuck you're right. I'm the one in the wrong here. I apologize, it wasnt a relevant time for me to be an ass

It’s great that you owned up. Many wouldn’t.

[-] Kedly@lemm.ee 3 points 1 year ago* (last edited 1 year ago)

Yeah, I may be a bit combative in my comments, but in general I dont want to contribute to toxicity, so when I'm wrong I'll fess up and apologize for it

I feel you and I don’t know your age but me personally I found that with age, I was more forthcoming with saying i was wrong and just trying to be nice to folk.

Have a great day dude!

[-] Kedly@lemm.ee 3 points 1 year ago

Age might play a part in it, I do think I've been more willing to fess up to wrongdoing than average throughout my life as well though as I function best in honest environments. You have a great day as well!

[-] Four_lights77@lemm.ee 2 points 1 year ago

Probably so it can detect it as quickly as possible for elimination.

[-] Rubanski@lemm.ee 7 points 1 year ago

Discoveries like this always makes me wonder, who had the idea to try it and why

[-] SpiderShoeCult@sopuli.xyz 2 points 1 year ago
