As stewards of the planet, let's unite to preserve this ancient marine creature and secure a brighter future for all species dependent on its survival.


The horseshoe crab is a magnificent creature that has withstood the test of time for over 400 million years1. But this primordial sea dweller now stands at a critical juncture, facing imminent extinction. As passionate individuals concerned about our planet's biodiversity, we must act urgently to save the horseshoe crab from vanishing forever.

Unraveling the Crisis

The horseshoe crab, a living relic from an ancient era, plays a crucial role in our lives and ecosystems. Its blue blood contains an invaluable substance called limulus amebocyte lysate (LAL), used to detect dangerous impurities in vital medicines2. However, the harvest of horseshoe crabs for this purpose has led to a significant decline in their population2.

Compounding this crisis is the impact on the red knot bird, a migratory shorebird that relies heavily on horseshoe crab eggs for sustenance during its epic migratory journey3. With horseshoe crab populations dwindling, the red knot's very survival hangs in the balance.

Understanding the Threats

Throughout history, horseshoe crabs have faced numerous challenges. Coastal development and industrialization led to the degradation of vital mudflat habitats, where the crabs lay their eggs. As these habitats dwindled, horseshoe crab populations declined4. From habitat destruction caused by human activities to historical harvesting for bait in the fishing industry, these resilient creatures have endured many hardships.

Today, their decline is primarily linked to the harvesting process for LAL, which results in the death of approximately 15% of the crabs. That's approximately 112,000 horseshoe crabs lost in 2021 alone5.

Our Call to Action: Saving a Precious Legacy

Now is the time to act! We can be the generation that stands up to protect the horseshoe crab and the web of life that depends on it. We must unite to create a sustainable future where this ancient wonder continues to grace our oceans for generations to come.

The Pledge:

As an individual deeply concerned about the fate of our planet and the precious species that inhabit it, I take this pledge to protect the magnificent horseshoe crab from the brink of extinction. This primordial sea creature, which has graced our oceans for over 400 million years, now faces unprecedented threats, and it is my urgent responsibility to be a part of the solution. I vow to take action, raise awareness, and collaborate with others to ensure a thriving future for the horseshoe crab and the delicate ecosystems it supports.

1. Advocate for Stricter Regulations I will tirelessly advocate for the implementation of more stringent regulations and guidelines for the harvesting and handling of horseshoe crabs. These regulations must be mandatory, leaving no room for ambiguity, to ensure the maximum protection of these ancient creatures and the red knot birds that depend on them.

2. Support Research for Synthetic Alternatives I will actively support and promote research efforts to develop synthetic alternatives to horseshoe crab blood for medical testing. By reducing the demand for wild harvests, we can alleviate the pressure on horseshoe crab populations and pave the way for more sustainable practices.

3. Protect Critical Mudflat Habitats I will join forces with conservation organizations to protect and restore critical mudflat habitats, vital breeding grounds for horseshoe crabs. By preserving these habitats, we safeguard not only the survival of the crabs but also the red knot birds that rely on their eggs.

4. Foster Public Awareness I will engage in public awareness campaigns to spread the word about the importance of horseshoe crabs in coastal ecosystems and the endangered status of the red knot. Through education, we can inspire others to take action and become champions for these vulnerable species.

5. Advocate for Mandatory Conservation Education I will work towards making conservation education mandatory in schools and communities, creating a generation of environmentally conscious individuals who understand the significance of protecting the horseshoe crab and its ecosystem.

6. Encourage Sustainable Fishing Practices I will support fishermen and fishing industries that practice sustainable methods, minimizing bycatch and avoiding harm to horseshoe crab populations. Collaborating with fishing communities will help foster a sense of shared responsibility for conservation.

7. Participate in Citizen Science Projects I will actively participate in citizen science projects that monitor horseshoe crab populations and their habitats. Contributing to data collection efforts will aid researchers and inform conservation strategies.

8. Promote Responsible Tourism I will advocate for responsible tourism in coastal areas where horseshoe crabs breed and red knot birds stop during migration. Responsible tourism can minimize disturbances to these vital ecosystems and promote the well-being of both species.

9. Collaborate with Local Authorities I will engage with local authorities and government agencies to promote conservation initiatives and ensure that the protection of horseshoe crabs becomes a priority on local, regional, and national levels.

10. Support Conservation Organizations I will donate my time, resources, and funds to support conservation organizations like GreaterGood, who are dedicated to protecting endangered wildlife and their delicate ecosystems. By contributing to their efforts, we can amplify the impact of conservation actions and create lasting change.

With every action I take, I will keep in mind the urgency of the situation. The fate of the horseshoe crab hangs in the balance, and we are at a critical juncture in history. I will not stand idly by as this ancient wonder slips away. By taking this pledge, I commit myself to be an advocate, protector, and ally for the horseshoe crab and all the species that rely on its existence.

Together, let us act with determination, passion, and urgency to preserve the horseshoe crab's legacy for generations to come. The time to act is now, and I pledge to be an unwavering force for the protection of this awe-inspiring species. Join me in this crusade to save the horseshoe crab and ensure a thriving future for all life that calls our planet home.
