Oregon Coast. The aquarium is accredited by the Association of Zoos and Aquariums. Main building Exhibits in the main building include four permanent displays: Sandy Shores, Rocky Shores, Coastal Waters, and a changing exhibit area. The first features fish and invertebrates that live either close to shore or in bays such as Yaquina Bay. Progressing, the aquarium displays feature animals further offshore ending in a kelp forest and sea jelly exhibit. Flanking the permanent displays are the changing exhibits. There are also exhibits focusing on small marine life in the area including jellyfish, and a tidepool exhibit in which visitors may touch sea stars and sea anemones. Temporary exhibits have included "Turtles," "Swampland," Claws that featured crustaceans, and Oddwater, which featured unusual sea creatures such as the green-blooded cuttlefish and the jet-powered chambered nautilus. Passages of the Deep The largest exhibit is "Passages of the Deep", in Keiko's former tank, it features walk-through acrylic tubes surrounded by deep water marine animals such as sharks, rays, and rockfish. Passages of the Deep was created in Keiko's former home, and has three sections. Orford Reef contains mostly rockfish and other smaller Pacific-Northwest fish. Halibut Flats contains halibut, ling cod, a small ray, and other large fish, and includes a mock sunken ship. Open Sea is the last section in the tunnel, and holds many species of sharks including seven gill sharks, as well as rays, mackerel, anchovies and salmon. Seabird Aviary The aviary at Oregon Coast Aquarium exhibits sea and shore birds. Those on display include the seabirds tufted puffin, common murre, rhinoceros auklet, pigeon guillemot, and the shore bird black oystercatcher. The seabird aviary includes two large pools and rocky cliffs. Nature Play Area The aquarium's nature play area offers an interactive exhibit for kids which features models of logs (in reference to the area's history in timber), a replica eagle's nest, and a slide designed to look like a river chute. Outdoor Amphitheater The outdoor amphitheater was built as part of the same renovation project that brought the nature play area and the headwaters feature. It is an outdoor presentation space that hosts educational presentations from experts and animal demonstrations from caretakers. Outdoor exhibits The Aquarium has the largest outdoor Seabird Aviary in North America, which is home to tufted and horned puffins, black oystercatchers, common murres, rhinoceros auklets and pigeon guillemots.
