ROYAL OAK, Mich. – The Detroit Zoo is debuting a new polar bear, Anana, to help the threatened species with its breeding efforts. Anana made her debut Thursday, on International Polar Bear Day. March marks the start of polar bear breeding season, which is already apparent for 15-year-old male Nuka and 7-year-old female Suka, who have been at the Detroit Zoo since 2011 and 2018, respectively. Anana is 19 years old and was previously at the Cincinnati Zoo to breed with another male polar bear. When that polar bear didn’t appear to be fertile, Anana was brought to the Detroit Zoo to breed with Nuka.
