Siku (born 22 November 2011 in Skandinavisk Dyrepark) is a male polar bear. He has several siblings such as Sné. After his mother failed to produce enough milk to feed him, he was taken into care in the Scandinavian Wildlife Park in Denmark.[1]
In terms of popular appeal, he is by some considered to be a possible successor to the polar bear Knut, who attracted worldwide attention at Berlin Zoo from 2006 until his death in 2011. A YouTube video showing Siku at the age of one month attracted hundreds of thousands of hits in just twenty-four hours and he was hailed internationally as an online sensation, especially after appearing on the official BBC website.
