Horseshoe Crab Moon

A free online on-demand showing of this fascinating documentary is planned for June 8-10. Sign up below to receive viewing information by email.

HORSESHOE CRAB MOON follows the scientists, researchers, and citizen scientists as they study the decline of the horseshoe crab along the East coast, and in particular the Delaware Bay. Horseshoe crab numbers have been declining rapidly over the last few decades due to the downturn in the Delaware Bay’s water quality, and the over-harvesting of horseshoe crabs for bait. The film also looks at the resulting crash of the red knot, a globe-trotting sandpiper, which depends on horseshoe crabs eggs for sustenance during its incredible migrations. The number of migrating red knots has dropped nearly 80% in the last few years.

The film also tells the inspiring story of the scientists and field biologists’ successful efforts to connect an ancient ecosystem with the interconnected relationship of the moon, tides, horseshoe crabs and sandpipers. Diligent data collection and scientific documentation is used to understand the interdependence of these populations, and guide the most effective way that scientists and the public can help in reinvigorating the horseshoe crab and red knot populations and restoring the health of the bay. 

“Horseshoe Crab Moon is a tremendous resource that provides insight into one of the great wildlife wonders of the world.” David Mizrahi, PhD, New Jersey Audubon Society
