Surreal Moment Adorable Polar Bear Appears To Wave To Photographer In Alaska

'We couldn't see it, but figured out later that the male was waking up and beginning to move. The nearer family started moving in our direction, away from the male, so Ketril began to move our boat away. I focused on the family in the distance and took this series of shots when I saw them standing and watching the other cubs with intense curiosity. Their behaviour at the moment this photo was taken differed from their usual playing or sleeping. They were all on alert, the mum was serious and anxious and the cubs curious and attentive.'
