FWC invites public to stalk mating Horseshoe crabs

Embrace your inner creepy animal stalker in the name of science!

JACKSONVILLE, Fla. – The Florida Fish and Wildlife Conservation Commission (FWC) is inviting the public to stalk and report mating horseshoe crabs, even providing tips for the best chance for catching a glimpse of the crabs mid bow-chicka-bow-wow. 

Spring is peak mating season for horseshoe crabs, and biologists with the FWC encourage embracing your inner creepy animal stalker and reporting your sightings with the FWC Reporter application.  

Horseshoe crabs mate year-round, and it is most common to see groups along the shore in March and April. To identify mating pairs, look for a smaller male on top of a larger female -- no judgment here -- horshoe crabs.

If you are into this sort of thing, you will likely have the best luck spotting horseshoe crabs around high tide at the beach, within three days of a new or full moon. The next new moon is March 6 and the full moon is March 21.    

These sighting reports provide important information about population distribution to the FWC. Although horseshoe crabs have existed for about 450 million years, little is known about Florida populations. Public sighting information helps FWC researchers target spawning beaches for the Florida Horseshoe Crab Watch Program, a citizen science initiative to collect scientifically accurate data throughout the state. 

When good love goes bad, you can help. If you see a horseshoe crab on its back, you can help it flip back over by gently picking it up (holding both sides of the shell), turning it over and releasing it back into the water. Simple actions like this help conserve this species and the many other species that depend on it.  

The FWC is definitely into this sort of thing and asks the public to report sightings through one of several options: Visit the Florida Horseshoe Crab Spawning Beach Survey on the FWC website. The FWC Reporter app is free to download on Apple or Android smartphones or tablets from the App Store and Google Play. You can also report findings via email at horseshoe@MyFWC.com or by phone at 866-252-9326.
