Captured in amazing details, the unique pictures show the alien-like anatomy of the shark and reveal rows upon rows of razor sharp teeth and white colored gills.

The incredible photographs were taken when a curious shark began to inspect the camera of British born photographer, Adam Hanlon, 46. After sensing electronic impulses omitted by Adams camera, the inquisitive creature began to gently mouth at the camera allowing him capture the unusual perspective.
