Horseshoe crabs have endured every single great mass extinction on this planet. It is such a resilient species, and we can bring it back—Deborah Cramer
"These crabs have saved countless human lives,” said Will Harlan, a senior scientist at the Center for Biological Diversity. “Can we return the favor?”
"Both H.898, before the Massachusetts legislature, and a proposal before the Massachusetts Division of Marine Fisheries (DMF), matter for horseshoe crabs on our beaches, and the abundant food their eggs might again offer to the Hudsonian godwit and the endangered red knot and other shorebirds."

When the Horseshoe Crabs Are Gone, We’ll Be in Trouble.
Deborah Cramer. New York Times. Feb. 16, 2023.
"In the United States, fishermen take some 1.4 million each year, killing almost half for use as bait. Pharmaceutical companies capture and extract blood from the other 700,000 to make the endotoxin test before releasing them to the sea. Up to 30 percent may die as a result. Many others never make it to shore to lay their eggs.
The International Union for the Conservation of Nature considers horseshoe crabs in the United States "vulnerable to extinction" along much of the East Coast and endangered in New England. Over 20 years of regulation of the horseshoe crab fishery by coastal states has failed to restore these ancient animals to their former abundance."

The Duke All Swell? team is joined by Dr. David Mizrahi, Vice President of Research and Monitoring at New Jersey Audubon. David is also one of the founders of the Horseshoe Crab Recovery Coalition, an organization dedicated to ensuring the future of the American Horseshoe Crab.
In this episode we hear from David about the surprising connection between two species: the Atlantic horseshoe crab and an endangered shorebird, the Red Knot. We learn about Red Knot migration, their reliance on horseshoe crab eggs, and how human industries have interfered with these populations. David shares insight about how the Coalition is working to protect the American horseshoe crab and how listeners can get involved.
