This level features animals that are native to Maryland. The four exhibits create the illusion that the viewer is traveling down a Maryland stream from its source in the Allegheny Mountains, to a tidal marsh, to a coastal beach, and finally ending at the Atlantic shelf. Featured animals include painted turtle, wood turtle, American bullfrog, and rosyside dace in the Allegheny Stream, diamondback terrapin, feather blenny, and sheepshead minnow in the Tidal Marsh, striped burrfish and blue crab on the Coastal Beach, and clearnose skate, Grouper and summer flounder in the Atlantic Shelf exhibit.
