  1. If humans were to find those where those babies hide, horseshoe crabs would probably become endangered. I’m glad humans can’t find them

  2. Hey Ted-Ed guy, you doing okay? You sound a bit sick today. The vocal fry is a bit on the stronger side.

  3. i actually help grow horseshoe crabs at school lmao. they're so much smaller than they are when they're adults (they've only malted four times since we got them!) so they're about the size of like a marble.

  4. The most interresting about the reason for the blood is blue is due to the copper content that has oxydised. Our blood is red because of oxydised iron. Yup.. our body is filled with rusty fluid.

  5. Humans:
    Any species that is not ours: does anything
    Humans: well buddy it looks like your ready to get eradicated

  6. Yeah. I was totally about to say "Why are we collecting horseshoe crab blood?"
    Jokes aside that sounds like a rare RPG item.

  7. There is a synthetic solution already.
    But pharmaceutical haven’t adapted it yet.

  8. It'd be nice if they manage to synthesize horseshoe crab. I wonder if it's possible to create a colony starting from captured babies and harvest smaller portions of their blood more regularly (by which I mean not only in warm months), at least in captivity there are no predators to prey on weakened crabs. Never mind, I don't have enough faith in humanity to believe that those crabs wouldn't suffer an equally horrible fate. I hope they can figure out how synthesize that blood soon

  9. How come they don’t tag them when they catch them so they can see where the horseshoe crabs go

  10. 2:15 "So scientists use an extract called LAL"
    Laffing Aut Laud
    😂😂😂😂😂😂
    I know its not funny

  11. Let them lay their eggs then harvest their blood so they can keep the population up while still getting their blood

  12. Why cant the just strap a camera or somethin onto it lmo. Then they would know it's secrets

  13. WHY DIDN’T THE SCIENTISTS JUST ATTACH SMALL GPS TO THE HORSESHOE CRABS WHEN THEY GO BACK TO THE SHORE
