At the San Diego Zoo, Africa Rocks

On Saturday, the San Diego Zoo will open its largest construction project ever. Spanning 8 acres, Africa Rocks will house African penguins, baboons, lemurs, monkeys, and, for the first time in the zoo's history, sharks. The exhibit replaces the area where Dog & Cat Canyon once existed, a part of the zoo that dated back to the 1930s. Often overlooked, the San Diego Zoo is also known for highlighting its botanical features and Africa Rocks will be no exception. According to a recent article from The San Diego Union-Tribune, "the zoo has a widely respected collection of some 700,000 plants, and Africa Rocks will feature specimens from the continent - the Madagascar mousetrap tree, the pincushion protea and the baobab tree." Another major draw of the area will be the exhibit's 200,000-gallon saltwater pool, which features a built-in power-washing system, because according to the same U-T article, "penguins poop a lot."
