That is one of the fascinating place to go, may be because even though we can dive and see everything with our own eyes but we are not able to see them so clear like due to our eye lens that is not used to see the objects under water. I remember myself spending hours observing the beauty of underwater life, many of fishes are colorful that is difficult to imagine under deep water.

You are lucky being able to capture the hammerhead shark the same time with ordinary one., I wonder if in real nature they could be neighbors too?
