The Delaware Bay contains the largest concentration of horseshoe crabs in the world. These enigmatic, unassuming creatures play a critical role in the coastal ecosystem: during their spring spawn, their eggs help maintain the health of the Delaware Bay fisheries and sustain tens of thousands of shorebirds as they make their way north to breeding grounds on the Arctic tundra.

In this video, find out how The Wetlands Institute is working with partners and volunteers to save horseshoe crabs through our research and conservation efforts, and through the reTURN the Favor horseshoe crab rescue program.
