Where’s That Ocean?

Horseshoe Crab makes its way back to the water after low tide.

Horseshoe Crab makes its way back to the water after low tide.

These photos follow the meanderings of a Horseshoe Crab as it finds its way back to the water. Taken at East Point, New Jersey, within sight of the Atlantic Ocean.

The Horseshoe Crab is protected. Once each year, crabs are rounded up and approximately 30% of each crab’s blue blood (blue because of copper content) is drawn (donated?) in specialized laboratories. The crabs are then returned to where they were collected. Each crab is likely to be collected to donate again the next year.

The blood is used to detect bacterial contamination on surgical equipment and in medicines. A solution of no more than five percent Horseshoe crab blood can detect dangerous bacterial toxins at concentrations of as little as five parts per million. The U.S. Food and Drug Administration (FDA) requires that intravenous drugs and all medical equipment coming in contact with the body must first pass through the crab’s blood, including needles, surgical implants and even pacemakers. This has significantly reduced the danger of life-threatening infections caused by contaminated instruments, implants and medications.
