As humans, we don't think twice when we see ourselves in the mirror. These wild animals have never seen a reflection of themselves, react in some fascinating ways.

French photographer Xavier Hubert Brierre and his wife set up a large mirror in numerous places in Gabon, Africa and filmed animal reactions to seeing themselves in the mirror

The amazing thing is how differently animals react to their reflection. There's curiosity, aggression, confusion and even ambivalence, as was the case with the elephant.

Of all the animals, the chimpanzees appeared to not only get the most enjoyment out of the reflection, but seemed to understand what they were seeing.

The two leopards were amusing but their reaction was a bit frightening. The same can be said for the gorilla who was quite aggressive to the reflection.
