The Kind of Luck Your Health Depends On!
Horseshoe crabs come from an ancient line. Their ancestors appeared in the fossil record about 500 million years ago. And, while the horseshoe is a very auspicious symbol that is used to protect against any forms of evil, the horseshoe crab protects many of us from many diseases.
Over the millennia, this group has developed a trait unique to the horseshoe crabs alive today: their copper-based blue blood contains bacteria fighting compounds that cause the blood to clot when exposed to bacteria fragments.
