Report a Tag
USFWS Tag Report
Have you seen a horseshoe crab with a circular tag on its carapace?
- Snap a picture of the tag or record the tag # (number is on the bottom of the tag, shown in the photo on the right).
- Note the date, location, and general condition of the crab (alive or dead)
- Report the data at the following link:
or by calling 1-888-546-8587 (1-888-LIMULUS)
DO NOT remove the tag. When recording the tag #, try to limit disturbance to the crab (try not to pick it up and if you must pick it up, NEVER pick it up by the tail).
Data goes into a national database maintained by the US Fish and Wildlife Service and contributes to knowledge about horseshoe crab movements and population numbers.
