Project Limulus
Project Limulus is a regional program organized by Sacred Heart University in Fairfield, Connecticut. The objective of this program is to better understand the distribution, movement, longevity, and mortality of horseshoe crabs in Long Island Sound. Horseshoe crabs are a near-threatened species, and overharvesting has led to a dramatic decline in the Long Island Sound. Participants can attend a virtual training session via Zoom to discuss the biology of horseshoe crabs, as well as the protocol for counting and tagging at the beach. A separate day will be dedicated to the beach event, participants meet at Hammonasset to take part in tagging and monitoring horseshoe crabs. Virtual session is free to attend. Field session is Members: $9; Non-members: $12.

Join us as we search for breeding birds and late migrants in some of the best spots in southeastern Connecticut.
