A diverse cast of animals adjust to life in the newest and fastest changing habitat on the planet -- cities -- as more and more wild animals make their home in urban areas. "Wild Metropolis" explores footage of these animals, and how they've applied their natural born skills and abilities to create their homes while also making great physical and behavioral adaptations. Narrated by Graham Vick, a wide range of species is featured, including humpback whales, megabats, penguins and Burmese pythons.
