Humpback: Birth of a Giant

S1, E4: In the waters off the west coast of Colombia, a baby humpback whale finds himself in an urgent race against time. He was born late and has just four months to bulk up before undertaking a 5,300-mile migration south. At 16 feet, he is vulnerable to large sharks and killer whales as well as adult male humpbacks that are dangerously vying for supremacy. However, he does have help: a devoted mother who will nurture him through sickness, protect him from attack, and prepare him for the epic journey to the frigid waters off Antarctica.
