This documentary is one of the best I have ever seen. It is very insightful to the way animals percieve the world around them, it made me realise just how different but also how amazing other creatures lives are to our own. I recomend that all of you out there that love documentaries should buy this, you won't be sorry. Very educational, I have learned things I never thought were possible such as how all organisms in the world have different perceptions of time. The filming of this documentary is awe enspiring, really breath taking. Something you will want to watch again, and again.
