For the first time this season, Amazing Wildlife highlights the Oceans hub, with a “deep dive” into the icy waters of the Arctic to look at polar bears! Rick and Marco are joined by Kelly Murphy, lead wildlife care specialist for the Polar Plunge habitat at the San Diego Zoo. Kelly introduces us to the three polar bears at Polar Plunge—Chinook, Kalluk, and Tatqiq—and explains the reasoning behind their names, which are from the Inuit language. We discover why polar bears are considered a marine mammal, and how they thrive at the San Diego Zoo. We’ll also hear how Chinook, Kalluk, and Tatqiq have helped scientists better understand polar bears and the different ways climate change poses a threat to their existence—and what we can do to help.
