Take our Horseshoe Crab Survey!

Help the Coalition to Save Hempstead Harbor track horseshoe crabs along the Hempstead Harbor shoreline during their 2022 mating season!

Typically in May and June, adult horseshoe crabs head to the shoreline to mate. This often occurs during a full or new moon. The next full moon is on June 14, and the next new moon is on June 28.

Tell us what you see to help us better understand their presence and behavior in Hempstead Harbor.
