+Kazi Islam, we seem to be one right now. The rate of extinction is currently way higher than it naturally appears to be.

These are the beginning sign of mass extinction if I recall correctly from my geology 101 class.

A story to share. I was at the beach with my family in the morning, and we looked out at sea and saw hundreds of dead horseshoe crabs, later that day I picked one up by its tail, then buried it and marked its grave with a stick.
For further information: - about a third of the blood is removed during harvesting - the most devastating to the population was by far the fishing industry until finally regulations were introduced some time around 2000, until then millions (!!!) of Horseshoe crabs were taken each year as bait for US fisheries (exact numbers aren't available because no one monitored it) - Horseshoe crabs aren't real crabs - there's a couple of species, some of them live in Southeast Asia, the biggest population lives in Delaware though
I remember when I was little my mom and I flipped over a horseshoe crab that was on it's back then we watched it return to the ocean, I was so proud of my horseshoe crab child.
When i found a couple of horseshoe crab when i was little, I brought them home and they died several days after that. Still feel bad of myself for that...
I am a student at a marine biology class and we sent letters to senators and other companies and told them about synthetic alternatives to LAL and how harvests of horseshoe crabs was not only affecting horseshoe crab populations and how it was also affecting a species of birds called the red knot which exclusively eat horseshoe crab eggs on their migrations anyway I was surprised you didn’t mention the red knot but still a awesome video
Why don't the scientists who harvest horshoe blood also protect the beaches where the horshoe spawn? That would give the crabs a steady and safe area to spawn and the scientists a steady supply of crabs.
I'd imagine it's an issue of money. Who is going to buy the beach when the sciences are already drastically underfunded? How are you going to pass laws to protect it if commercial interests want it?
Ivan Johnson well we are more precise and widespread than a commet tho you can't blame them but we also need them so stopping killing them is not a good idea either
Imagine that the horseshoe crabs actually go to an area where known and unknown prehistoric creatures hide. Like a single area hidden from humans where the old ways of the aquatic still exists.
I remember me and my sister would always go to the beach and use the dead horseshoe crab shells as helmets we once’s when put one on her head but it was still very much alive.
I use to play with them as a kid. West coast FL... creepy lil critters but totally harmless. I haven't seen them around in 20 yeas.... didn't know we milk their blood- 😬😢
We most likely will, considering our utter dependance on them in medicine. Let's just hope we either find a way to restock their population or finally having a formula for a synthesized alternative.
We depend so much of our survival on amazing creatures like these yet we fail to protect them. Our arrogance towards other species will be our downfall.
They are very much protected there are huge no take zone called the shuster horseshoe crab reserve the crab that is harvested in the small area that is open to harvest has a 4% mortality rate the 15% estimated is from a bias source

Human blood is great for removing Oxygen out of our Methane craving bodies, don’t worry, we only borrow about a few hundred million of your species. Unfortunately it’s a pain to send you all back so. . . .we just drain you completely. Sorry.
I've seen some kids at a beach bashing a horseshoe crab with a basketball size rock. By the time I got there and stop them I found the horsecrabs body mangled and crushed. Those damn punks just stared at me like I did something wrong to them when I push them aside.
Horseshoe crabs are the MVP of 2019. Thanks Elizabeth Cox for the information. I wanna block the haters like horseshoe crabs block the pathogens with amebocytes.
If my son is dying and Dr said only horseshoe crab blood can save him but it’s illegal to harvest it, i would not think twice. It’s easy to blame science for decline in horseshoe crabs, but when lives are at stake, we do not have an option until there is an alternative.

- Horseshoe crabs aren't real crabs
- there's a couple of species, some of them live in Southeast Asia, the biggest population lives in Delaware though
Ah, and the blood is blue because it has copper instead of iron.
yes you are right and if you look at the marine fisheries reports in the states where they are protected, their populations are increasing.
