New Lifeblood for Atlantic Horseshoe Crabs

It's a full moon high tide on Sunray Beach in Villas, New Jersey, not far from Cape May, and Atlantic horseshoe crabs (Limulus polyphemus) are emerging from the sea. On this day in late May, female crabs, often with several males attached, make their way inch-by-inch from the bay to sands higher up the strand. There they will lay their eggs. On the previous high tide, many did just that, leaving signs of their passage in tracks in the sand.
