When you think of Cape Cod what comes to mind?

The feel of shifting sands between your toes?

The smell of seaweed and salt spray?

The sight of sea shells strewn on the shore?

The sound of smooth-sliding, ocean surf?

The Cape, a natural masterpiece, has a remarkable diversity of both freshwater and saltwater habitats for visitors to experience.

In the Cape Cod Museum of Natural History’s aquarium, you can discover the exciting nature of marine science in nearby ponds, streams, creeks, marshes, beaches, tidepools and Cape Cod Bay.

Remember, Cape Cod is basically a pile of clay, sand, gravel and boulders formed during the last Ice Age. During the thousands of years the glaciers retreated dropping massive chunks of ice that eventually formed ponds. Today, water from these ponds flows into our Stony Brook back yard and downstream to the Bay.
