Berlin Zoo - Germany

This is Knut. After the unproblematic gestation time of the 20-year old polar bear Tosca, Knut and his brother were born on 5 December 2006. Tosca, who is a former circus performer, rejected Knut and his brother. After four days, the brother died and Knut was separated from his mother by zoo workers. He was the first polar bear to have been born and survive in Berlin Zoo for over 30 years, being the size of a guinea pig facing an almost certain mauling by his mother.[2] He spent the first 44 days of his life in an incubator before zoo keeper Thomas Dörflein began handraising the cub.[3] Knut's need for around-the-clock care required that Dörflein sleep on a mattress next to Knut's sleeping enclosure as well as feed and accompany him on his shows for the public. As a result, Dörflein has become a minor celebrity.[4]
