UNTAMED SCIENCE: North Carolina Zoo and Polar Bears

For these iconic Arctic animals, breeding isn't as easy as it looks! With populations dwindling in the wild, AZA-accredited zoos play an important role in raising awareness about the threat of climate change and habitat loss and ensuring the species survives - and thrives. Our polar bears Nikita and Anana have the best of both worlds - their Tundra and Arctic Waters habitats mimic the wild environment. Their outdoor pools, indoor quarters and flooring are a chilly 55 degrees year-round. However, they've also been spotted sunbathing on warmer days.
