The Desert Sea is an Ultra High Definition 2 part series that centers on North America's diverse Sonoran Desert. The first hour explores why the Sonoran is the wettest and most diverse desert in the Americas due to its unique proximity to the Gulf of California and the great Pacific Ocean - a coastal desert next to an extraordinary rich marine environment of sea lions, dolphins and even blue whales. The second hour focuses on the abundant and diverse creatures that have adapted to desert life in this unique environment: from big cats, giant hares and killer insects, to extraordinary reptiles and even a bird that can run at high speeds.
