  1. Did you know that some people are harvesting their blood recently? Pretty sad cause it can lead to over exploitation, but quite revolutionary in the medical industry.

  2. I’ve got a question for you. Was the sound in the part where the horseshoe crab flips over natural or was that some foley work?

  3. I'm surprised you didn't mention their copper-based blue blood. "Unlike vertebrates, horseshoe crabs do not have hemoglobin in their blood, but instead use hemocyanin to carry oxygen. Because of the copper present in hemocyanin, their blood is blue." [Nature] Also, their blood sells for $15,000 a quart to researchers and even more to the pharmaceutical industry.

  4. They are the one of the most helpful creatures we can find, it's just some people don't aware of it yet. Their copper-contained blue translucent blood is playing a great role in testing new medicines whether the medicine is contaminated with bacteria or any other infected materials.

  5. I have been waTchign this channel for 2 years but I was really young and didn’t know how to subscribe and stuff but now I subscribed 😀

    What happened to the intro? Hi I’m Jonathan Bllue… and welcome to my world! or something

  6. can you imagine going to a bar to pick up some hot ladies and a giant picks you up and interrupts? I would be cranky, too.

  7. i love how they dont even try to pinch people when they get picked up… what a completely harmless creatures
