Help SCDNR study horseshoe crabs

by | April 4, 2019 3:09 pm

Now is the season when one of the most fascinating animals on our coast comes ashore to spawn, or lay eggs – and SCDNR biologists want your help finding them!

Help us learn more about our horseshoe crab population in South Carolina! We know that horseshoe crabs use the South Carolina coast to lay eggs, or spawn, and our biologists need your help identifying which areas the crabs are using in 2019. Your data will help us better understand these amazing animals and make informed decisions about our shared natural shorelines.

What does horseshoe crab spawning look like? Spawning horseshoe crabs typically occur in groups of two or more crabs along the shoreline. Spawning horseshoe crabs are not single crabs or upside-down, stranded crabs.

We’re tracking the locations of spawning horseshoe crabs on South Carolina beaches to learn more about the habitats where they lay eggs. Your sightings will help us better understand and protect these unusual creatures, which play a critical role in human health and the coastal food chain. 

If you’ve seen spawning horseshoe crabs recently, please take a few minutes to complete our online reporting form below.

The form should take approximately five minutes to complete. The information submitted will only be used to contact you in the event our biologists have follow-up questions. If you have any concerns or questions, please contact Kristin Hamilton at

One of the questions requests the GPS coordinates (latitude and longitude) of your sighting. Please use an application such as Google Maps to find those coordinates before completing the form.
