What is that in the sand?

"Horseshoe crabs are arthropods that live primarily in and around shallow ocean waters on soft sandy or muddy bottoms. They will occasionally come on shore for mating. They are commonly used as bait and in fertilizer, and in recent years there has been a decline in number of individuals, as a consequence of coastal habitat destruction in Japan and overharvesting along the east coast of North America." excerpted from Wikipedia

As I walked around the beach yesterday, I saw many of dead horseshoe crabs washed ashore around Cape May beaches. This particular dead horseshoe crab had an open/cracked shell that filled with sand and the tail was apart from the body, laid next to it.

To capture for a dramatic look of this image, I kneeling down on my knees and put my elbows on the sands. Hope you enjoy it!
