52. Water all around
Sightseeing in Sydney picture - A very interesting part of the Sydney aquarium is near the exit, where you enter a portion where there is water above, below, and all around you. A section of this is seen here. My wife who is posing here, got up with a startled scream when a shark headed straight for her. You can see the beast approaching just above her head. She suddenly turned and and came face to face with it.
