penguins. Guests learned how penguins survive in the wild and how to protect them. Move It! Marine Mammals in Motion Coinciding with the opening of the New Balance Foundation Marine Mammal Center in 2009, Marine Mammals In Motion highlighted the athleticism of the aquarium's harbor seals, sea lions, and fur seals and encouraged young guests to be physically active in their lives. The Marine Mammal Center continues to draw connections between marine mammals and humans and point out the challenges marine mammals face in our oceans today. Turtles Uncovered In this 2008 exhibit, visitors learned that turtles and tortoises have lived on Earth for about 300 million years, long before the dinosaurs were around, but that now some turtles are faced with the threat of extinction due to pollution, habitat loss, and global climate change. Killer Instincts This special program in 2007 helped visitors learn about the animals that we fear the most. The special program included an interactive passport program along with live animal presentations and a large-format, high definition shark video. Prehistoric marine reptiles appeared in 3D at the Simons IMAX Theatre in Sea Monsters: A Prehistoric Adventure. Featured animals included the sand tiger shark, anaconda, great barracuda, electric eel, lionfish, moray eel, giant Pacific octopus, and southern stingray. Conservation Historically, the aquarium has been active in marine mammal rescue on the New England coast. At one point, the rear of the main building was occupied by a marine animal hospital. The aquarium’s current harbor seals were born to individuals rescued from the wild early in its history, and its California sea lions and northern fur seal were deemed non-releasable after being rescued on the West Coast and Alaska. In 1999, the aquarium opened a new facility for rehabilitating harbor porpoises in Duxbury. However, the passage of the Marine Mammal Protection Act of 1972 caused the previously imperiled populations of marine mammals like Atlantic harbor seals to rebound, leading the aquarium to transition away from marine mammal rescue in favor of research, advocacy, in particular for the critically endangered North Atlantic right whale, and the rescue, rehabilitation, and release of cold-stunned sea turtles stranded on Cape Cod. As a member of the Association of Zoos and Aquariums (AZA), the aquarium participates in the Species Survival Plans for African and southern rockhopper penguins, the wild populations of which are threatened by habitat loss. The aquarium also aquacultures certain exhibit
