Donut Tank

This unique exhibit gives our summer flounders and sea robins the impression that they are swimming in an endless sea. It is beautifully lit by the blue light of the angelfish breeding tank.


A special pufferfish demonstration is held here during field trips, weekend public hours at 4:00pm, and as a grand finale for our birthday parties.


Here you will find our rare lobster “color morphs”. Blue, gold, yellow and calico lobsters will help you learn about these amazing creatures that may live for over 100 years.
