This is a giant model of the blue crab, taken in Baltimore's Science Center. This model used to be animated but the last time I was there and took this shot it was not moving.
Maryland is known for it's association, preparation, and festive digestion of the blue crab as well as other seafood which was once abundant in the Chesapeake Bay. The bay waters which run through our state are now very poluted with the major causes being runoff from farm land as well as wastes from industrial plants. There are efforts in motion to help reverse this condition but it may well be too little, too late. Red/Cyan 3D glasses required for viewing.
