I have never seen crabs like these in my entire 56 years! They are the color of sand......a very good disguise for these little things. There are millions of them.....skittering across the sand......and the closer you get to them they find a hole and away they go. I was fascinated by how comical they actually were to watch. They are about an inch to two inches. Some small.....some a little bigger.
The picture of the shoe was just because......a lone shoe on a big beach.
