Each year, hundreds of critically endangered manatees are killed in U.S. waters by boats, disease and cold weather. 2006 was the worst year on record for manatee deaths – 416 animals perished. With only a few thousand remaining in the wild, mostly in heavily developed Florida wetlands, the clock is ticking in efforts to save this amazing mammal from extinction. Another rare species and close relative of manatees is the dugong. Dugongs cling to survival in a few isolated corners of the globe. In marine sanctuaries in Abu Dhabi, the bizarre animals have been notoriously difficult to find, let alone photograph. Manatees and Dugongs features exclusive HD imagery of the mammals in the wild and examines efforts of scientists to protect the two species. The program also includes thrilling captures and field exams of manatees in Florida.
