Horseshoe crabs are one of the oldest known living species of animals on earth, and it is believed that they lived in the ocean more than 600 million year ago. These interesting creatures will be the focus of the program at the March 21 Sanibel-Captiva Shell Club.

Guest speaker Mark Thompson, MS, a research associate at the Sanibel-Captiva Conservation Foundation, explored the secret life of horseshoe crabs when he headed the horseshoe crab program at the South Carolina Marine Resources Research Institute.

The Sanibel-Captiva Shell Club meeting is Sunday, March 20 at 2 p.m. in Auditorium Room “A” on the main level of The Bailey-Matthews National Shell Museum. Door prizes will be awarded and refreshments will be served. The meeting is open to the public.
