Average lifespan of a fiddler crab in months.

On the outer shore of Falmouth Harbor, I saw hundreds of fiddler crabs near the high-tide mark. I'm guessing these were Atlantic Marsh Fiddler Crabs, but please don't quote me on that. The sand was dotted with burrows, and as I walked along, stampedes of crabs scurried to the safety of their burrows. A friend describes it as looking and sounding like a parting of the tides -- it sounds like a rush of water.
