If you've ever had a flu shot, know someone with a pace maker or joint replacement, or have given your pet a rabies vaccination, you owe a debt of gratitude to the horseshoe crab. Vaccines, injectable drugs, intravenous solutions, and implantable medical devices, both for humans and animals, are quality checked for safety using a test that comes from the blood of horseshoe crabs.

Humans can become sick if exposed to bacterial endotoxin. It is especially dangerous if endotoxin enters our blood stream directly, such as from an injectable drug. Given this, drugs and medical devices that come in contact with our blood stream are tested to help assure they do not contain harmful levels of endotoxin.

Like other animals, the horseshoe crab has an immune and blood coagulation system that protects it against infection. Inside the horseshoe crab’s blood cell (called the amebocyte) are the protiens of its blood clotting system. These proteins are released in response to the presence of unwanted organisms like Gram negative bacteria and cause its blood to clot around the injury and bacteria, protecting the animal from further harm.

To the question, partially Yes. Whistle
I had read it earlier that there are some creatures whose blood is not red, reason being absence of hemoglobin. Can't remember specifically about horseshoe crab.

Thanks for sharing the piece of information.

I studied their morphology when I studied Paleontology, they are as old as the Ordovician period meaning the shared the seas over time with now extinct creatures such as Graptolites, Ammonites and Trilobites, yet the Horseshoe crabs still survive. In the time they have lived the dinosaurs came and went on land.

Many people call them "living fossils' due to this.
