text: African penguins swim by an underwater window in Penguin Coast the new home for the birds, which opens this Saturday at The Maryland Zoo at Baltimore. The new exhibit allows spectators to view the penguins as they maneuver beneath the water in the 165, gallon pool. The state-of-the-art facility, built to resemble the rocky coast of southwest Africa where the species lives, will allow visitors to circle the exhibit, getting a much closer view of the penguins and white-breasted cormorants.
