The jaguar is considered the most mysterious and magnificent of all big cats. Ancient cultures considered them gods for their power, beauty and speed. But little is really known about this species that stalks the deepest jungles. Researchers have collected information about male jaguars, but half of the picture is missing as we know remarkably little about females. For the first time, Boone Smith brings his expertise to Central and South America as he teams up with Dr. Howard Quigley, who leads Panthera’s Jaguar Program. They are on a mission to capture, film and attach sophisticated tracking collars on the cunning and elusive jaguars – including a female – in the jungles of Belize and the swamps of Brazil, and finally enter the jaguar’s secret lair.
