It’s one of our biggest events of the year, and this time International Horseshoe Crab Day will be even more special. 2026 marks the tenth year of our Horseshoe Crab Aquaculture Program, which has been educating people about these incredible ‘living fossils’ as well as working to protect the species. We will also have special guest speaker Lina DiNunzio, from Manomet Conservation Sciences, who will be talking about her work monitoring horseshoe crabs at the Monomoy National Wildlife Refuge Center.
