Horseshoe Crabs in the Americas


Dr. Carl N. Shuster, Jr. passed away peacefully at home on May 28, age 100 years.

Virginia: Dr. Shuster was considered the worldʼs greatest authority on Limulus polyphemus, the American Horseshoe Crab, which he fondly called “the Animal”. In 2001, the U.S. Government set aside hundreds of square miles in the Atlantic Ocean off the New Jersey and Delaware coast named the “Carl N. Shuster, Jr. Horseshoe Crab Reserve”. When Dr. Shuster was over 80 years old, Harvard University asked him to write a book dedicated solely to the horseshoe crab. He recruited colleagues to be co-authors and the book, The American Horseshoe Crab, was published in 2003. download the pdf.

ERDG’s Horseshoe Crab Stranding Mitigation Project

Delaware: On May 1st, 2020, for the third year, ERDG in partnership with the community of Pickering Beach and the Delaware Department of Natural Resources and Environmental Control (DNREC), installed a 350-foot long temporary barrier across a Northern section of Pickering Beach, so as to prevent spawning horseshoe crabs from becoming stranded in this backwash area. Over the past three years that this program has been in effect, many thousands of horseshoe crabs have been saved. Pickering Beach, Delaware is one of the most productive spawning beaches in the world. This year in keeping with Covid-19 social distancing policies, ERDG’s founder and president Glenn Gauvry and board member Ariane Mueller, over a period of four hours, installed the barrier alone. Next year we look forward to working with our team of volunteers as in years past. Just flip ’em!™ view installation time-lapse


International Horseshoe Crab Day

The members of the International Union for Conservation of Nature (IUCN) Horseshoe Crab Specialist Group, of which ERDG is a founding member, invite you to celebrate International Horseshoe Crab Day with us on June 20th, 2020, by educating your community about the importance of this ancient mariner and its habitat, both marine and terrestrial. Unfortunately, Covid-19 social distancing guidelines prohibit most public gatherings. However, the power of social media to connect voices in celebration from around the world, is only limited by our imagination. Over the next few months, and particularly on June 20th, please share your celebration with us and those within your sphere of influence, via your social media formats of choice. Collectively, we can overcome the indifference that too often surrounds this remarkable living being. Begining the end of April, through June 20th, ERDG will be posting songs, poems, tales and images in celebration of the world’s four horseshoe crab species, that we have worked to protect for over 25 years. Please join us. Invitation English & Chinese
