Through stunning black-and-white images, award-winning photographer Christian Vizl uses a masterful control of light and shadow to portray the creatures of the sea as they are rarely seen, at home in the ethereal world beneath the waves.

Capturing a range of underseas scenes and moods—from the ferocity of sharks to the playful dance of dolphins—Vizl turns aquatic creatures and marine seascapes into visions of sublime grace and beauty suspended in time and space. With each turn of the page, venture deeper into the one realm in which humans do not reign and discover an unforgettable world that few have ever seen.

Though the ocean covers more than 70 percent of planet Earth, over 80 percent of that vast underwater wilderness remains unexplored. As the impact of human activity reaches these once-untouched regions, it is more important than ever to acknowledge both the preciousness of our seas and the necessity of protecting one of Earth’s last truely wild frontiers. Silent Kingdom is both an ode to the beauty of the ocean and the magnificent creatures that inhabit it and a call to action to preserve our planet’s fragile underwater world.
