In the next three episodes the journey moves into three radically different worlds where survival depends on mastering water, ice and extreme seasonal change. In the Amazon, giant river otters hunt as a family, black caimans ambush newly hatched turtles, army ants sweep through the forest in highly organized raids and a harpy eagle guards a vulnerable chick high above the jungle floor. The rainforest emerges as a vast living system, shaped by rivers, floods, towering trees and countless species competing for food, space and the chance to raise their young. The story then heads north to Alaska and Canada, where polar bears wait for sea ice, wolves struggle through blizzards, hares evade lynx and immense caribou herds cross dangerous meltwater rivers during their ancient migrations. Finally, along the Gulf Coast, flooded swamps and subtropical wetlands become the stage for black bears, alligators, manatees, burrowing owls and one of America’s rarest wild cats, the ocelot. From the frozen Arctic to the humid marshes of Louisiana, Florida and Texas, these episodes reveal how animals adapt to landscapes that can change completely from one season to the next.
