Horseshoe Crab Tracker

About the Horseshoe Crab Tracker

Horseshoe Crab Tracker is a community science project that engages Long Islanders in an effort to monitor and record the distribution of horseshoe crabs in our region. Participants are simply asked to report any horseshoe crab sightings through our data collection system. Reports can be submitted through the data form below or on a mobile device through the free Survey 1-2-3 app. 

Please contact Arielle Santos at asantos@seatuck.org or 631-581-6908 with any questions regarding the survey.
