I remember seeing images of a polar bear seeming to be playing and being 'friendly' with sled dogs. At the time I thought that there was no way that bear was really 'playing' that he was in fact acting like cats do when they have a mouse. The play that inevitably ends in a kill and it seems that is what has happened with the polar bears. Anthropomorphism is the attribution of human behaviour and characteristics to animals and leads us to misunderstand other species. For all we know other species have very little in common with us and the emotions and characteristics we exhibit. That we insist on analysing animals behaviour as similar to our own is not accepting their very unique differences.
