Most mammals are not self-aware, though. Place a rat in front of a mirror and it will not recognize the image it sees as itself. While with some degree of truth it can be said that they are simply aware, with very few exceptions mammals -- to say nothing of less complex organisms or subatomic particles -- are not conscious (i.e. self-aware) by the definition you just provided.
I think you should deeply consider the question of consciousness before you claim to know about it. The fact that 'aware', 'self-aware', and 'conscious' are all used interchangeably by you shows that either you have not mentally made a distinction between them, or you are being too imprecise with your language to effectively convey your thoughts
