Why are horseshoe crabs important?
The horseshoe crab is one of the oldest living species on our planet. Find out what makes this ancient species so special.
Why are horseshoe crabs harvested?
The horseshoe crab has historically been harvested for several uses including fertilizer and bait, and more recently for their blood.
Why is current horseshoe crab management not working?
The current harvest for horseshoe crabs is unfortunately mismanaged, leading to lower horseshoe crab populations across the Atlantic Coast.
Are horseshoe crabs important to fish?
Horseshoe crab eggs and larvae provide a rich and energy-dense source of food for many species of fish in the Delaware Bay
What is lysate and why is it important?
Limulus amoebocyte lysate is a chemical extracted from horseshoe crab blood that is used to test pharmaceutical drugs and equipment for contamination. Learn more about this process and the alternative that can prevent the bleeding of more crabs.
Revive & Restore: Biotech Can Save This Threatened Keystone Species & Keep Covid-19 Vaccines Safe
New European guidelines for endotoxin testing went into effect on January 1, 2021. These guidelines allow for the use of the synthetic alternative (rFC) in place of the horseshoe crab-derived endotoxin test (LAL) in drug manufacturing. Especially now, when billions of Covid-19 vaccines are in development, it is time to adopt rFC, the more sustainable, more consistent equivalent test.

Tracking the Red Knot: The nine thousand mile journey of a nine-inch shorebird
We’re excited to bring you a new story map that highlights the arduous 9,000-mile journey of the Red Knot, from its wintering habitat near the tip of South America to its breeding grounds in the Arctic tundra. The Red Knot depends on horseshoe crab eggs to fuel their annual migration.
The map was developed under the direction of Dr. Richard E. Lathrop Jr., Professor of Environmental Monitoring at Rutgers University, and coalition founder Dr. Larry Niles.
