We are all heartbroken by the sudden death of one of the world's most famous Polor Bear, Knut.
The necropsy, or animal autopsy, of the 4-year-old bear, which was undertaken Monday, showed brain anomalies that may be the cause of death.
A press statement from the zoo stated:
"The preliminary results show distinctive anomalies at the brain, which could be seen as the cause of the ice bear's sudden passing. Other irregularities on the organs could not be found from the pathologists."
Death at such a young age is rare, as male polar bears tend to live into their mid-30s in zoos and between 15 and 18 years in the wild.
