Descend into the twilight zone, a place where sunlight is scarce and divers with traditional scuba gear cannot go. In the narrow band between the light-filled shallow reefs and the pitch-black deep sea, these little-known mesophotic reefs—located 200 to 500 feet beneath the ocean’s surface—are home to fascinating and diverse marine life. Every dive yields surprising discoveries, and in Twilight Zone: Deep Reefs Revealed, you’ll see new and rare species, many of which have never been displayed in a public aquarium. Explore the great unknown alongside our scientists as they uncover what secrets these uncharted places may hold for the survival of the world’s coral reefs.
