Cape Cod's Nature Place

The Cape Cod Museum of Natural History

Aquarium: One Cape / Many Waters

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 our aquarium our goal is to help you discover the exciting nature of marine science in nearby ponds, streams, creeks, marshes, beaches, tidepools and Cape Cod Bay... all here at Cape Cod's Nature Place.


Aquarium News!

  • A special thank you to Captain Paul Young of the Pauline out of Sesuit Harbor who rescued a male seahorse suffering from Gas bubble Disease. The seahorse is now living healthy and happy in our aquarium. 
  • Construction is underway for a new horseshoe crab tank! 

Head Start: Spotted Salamanders


An egg mass was collected from Mother’s Bog. The egg mass contained approximately 25 eggs. Sphagnum Moss was collected for habitat purposes. Eggs hatched and developed into terrestrial juveniles over the summer. They were measured and released Oct 2, 2018 back to Mother’s Bog. 

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.
Cape Cod family activities

You'll learn the importance of our salt marsh ecosystem that supports a diversity of plant and animal life and our kettle ponds groundwater that is the Cape's sole source aquifer.

Like Cape Cod, our aquarium is ever-changing and exciting. Here is a partial list of the Cape Cod creatures you will find although it is important to remember that the species exhibited can change very often:

The exhibit graphics were made possible by the generosity of the BILEZIKIAN FAMILY FOUNDATION.
