If you see a tagged horseshoe crab here’s what you do.
As we reported in a previous social media post, reporting any sighting of a tagged animal is very important, and that includes tagged horseshoe crabs.
The Horseshoe Crab Cooperative Tagging Program in the U.S. is coordinated by the U.S. Fish and Wildlife Service. Tags are dispersed to state agencies, universities, and non-governmental organizations and are carefully attached onto healthy, mature horseshoe crabs on the left posterior point of the prosoma near the dorsal edge.
If you find a tagged horseshoe crab, do not remove the tag. Keeping in mind to limit disturbance to the crab, record the tag number by either taking a photo or by writing the tag number down, preferably without picking the crab up. Note the date, location, and condition of the crab (alive or deceased).
Report resighted horseshoe crab tag numbers at www.FWS.gov/crab tag/ or by calling 1-888-LIMULUS (1-888-546-8587). In return, you will receive information on when and where the crab was tagged.
Information collected as a function of resighting a tagged horseshoe crab provides data on horseshoe crab distribution, movement, longevity, and mortality.
