Is the biotechnology industry contributing to the horseshoe crab’s decline?

The horseshoe crab is a paradoxical creature: Its spiky tail and helmet-shaped body make it one of the most medieval-looking members of the animal kingdom, while its milky blue blood is essential to ensure the safety of cutting-edge biomedical devices and drugs.For decades, biotechnology companies have harvested horseshoe crabs and bled them to extract a substance used to create a sensitive test for bacterial contamination in intravenous drugs and devices.Studies have found that the vast majority of horseshoe crabs survive the procedure, but researchers at Plymouth State University and the University of New Hampshire began to wonder whether the bleeding might have other, less severe effects that could play a role in a recent population decline.
