July 25th, 2012. Salt Marsh This is the only section of the aquarium that is outdoors, although it is still enclosed via a thin metal wire. A large touch tank has southern stingrays and Atlantic stingrays, while a long, narrow, open-topped exhibit that has a massive river in the background has several species of fish and turtle but zero signage so I frustratingly could not find out exactly what species they are. There are even a few gulls inside this area and the view to a unique-looking bridge is quite splendid. An indoor touch tank has the usual assortment of crabs, urchins and anemones.
