I came across these VERY cool pictures in the Daily Mail. Odin lives at the Six Flags Discovery Kingdom Zoo in Vallejo, near San Francisco. He is about 10ft long from nose to tail, and is an excellent swimmer. White tigers - the colour is caused by an unusual genetic combination - are rare in the wild, although there are several dozen in zoos.
Imagine swimming and seeing this coming at you while scuba diving... CRAZY
Here he looks so sweet!
