If you walk out to the beach at the Wellfleet Bay Wildlife Sanctuary at low tide you can see thousands and thousands of Fiddler Crabs scurrying about the mudflats and into their little holes in the mud. They are everywhere!
You can see the vast mudflats in the second photograph. They seem to go on forever.
Have you ever seen a Fiddler Crab? You can tell the males by their exceptionally large claw which is shaped like a fiddle, thus the name “Fiddler Crab.”
