These pictures were put together because they are part of a sequence. The first photo is the dolphins jumping into the air and the second photo is them in mid-air and the last photo is the dolphins diving back into the water. I think that dolphins are so beautiful because everything they do looks like it is perfect. I think this because dolphins are smooth with barely any bumps so it is easy for them to move. For some people this could be a metaphor. For example, that life can sometimes be smooth and easy and then the dolphins falling could be that life can also be hard.
