Did you know that horseshoe crabs have bright blue blood? I was blown away when I learned that fact, this oddity of nature making my heart leap with curiosity and wonder.
They also deserve our reverence. They are survivors, predating dinosaurs. In their modern iteration, though, they are becoming increasingly endangered. That bright blue blood of theirs? It coagulates when it is exposed to bacterial endotoxins, which has both kept them alive for millions of years and happens to be the reason we have vaccines (A Horseshoe Crab’s Blood is Vital in Testing Drugs, Washington Post August 1, 2o21).
If you live on the East Coast of the U.S. (and maybe elsewhere, but I don’t know about elsewhere), you’ve likely seen the discarded shells of these prehistoric-looking creatures on the beach. These creepy/cool little armored tanks are so much a part of the seascape that I have never really given them much of a second glance, their remnants being fought over in a screeching battle by seagulls or half buried in the sand amongst the shells and seaweed, periwinkles and rocks (yes, New England beaches feature rocks) as familiar as the sound of crashing waves. They deserve a second glance, our admiration, our gratitude, and our protection.
