fiddler crabs

As I walk on the boardwalk away from the fire watchtower, I detect a movement in the sand of the beach off to the left. I look down at the sand and see a crab with a claw that is the size of his body. I realize there are holes in the sand that the crabs made. I didn’t notice the holes before now. Outside the entrances of the holes are piles of balls of sand. As I watch, more crabs come out of the holes. They are filtering particles from the sand to eat. Any movement, even wind or a breeze, and they dart back into their holes. Some do not dart back into their holes but keep sifting sand as if there is nothing to worry about. People jog by to get exercise by going up and down all the stairs in the fire watchtower. I hear them pant as they pass me. I expect someone to stop and see what I’m bent over looking at, but no one does. This disappoints me, but I’m also glad. I don’t want to share the fiddler crabs.
