What do we use this incredible blood for? A sort of witchcraft, you might say, for it literally keeps people alive. Horseshoe-crab blood is exquisitely sensitive to toxins from bacteria. It is used to test for contamination during the manufacture of anything that might go inside the human body: every shot, every IV drip, and every implanted medical device. Truely amazing!
And if that wasn't enough, the Horseshoe crabs are known for their epic orgies.
