Biologist Sheila Eyler tag a female horseshoe crab on Bowers Beach, Delaware

Biologist Sheila Eyler from the FWS Maryland Fisheries Resource Office, Annapolis, MD is tagging a female horseshoe crab on Bowers Beach, Delaware. The male and female horseshoe crabs come up during high tides, couple together, and spawn on the beach. Sheila is drilling a small hole into the larger female (in front) with a portable drill and then the plastic identification tag is riveted in the hole. This helps the biologist track the movements and life histories of this little known species. (electronic image) Photo taken: June 9, 2002/Robert Pos 703-358-2323
