Horseshoe Crab Tagging At Circle Beach

Open Event

Search for horseshoe crabs on the day of the full moon. As citizen scientists for Project Limulus we will count, measure and tag the crabs as part of a long-term study of horseshoe crab (Limulus polyphemus) population ecology. Each spring, horseshoe crabs come ashore to breed, often during the full and new moon high tides. Learn about this living fossil’s important role in coastal ecology, and the valuable component of their blue blood that benefits human health. Be prepared to walk a mile along a rocky beach, and wade knee deep into the water. Sturdy waterproof footwear is recommended.
