Combat in the sea takes viewers into the ocean's sparkling, tropical reefs and rough open water. In our planet's liquid space, predators of all shapes and sizes face incredible obstacles to success - and survival, because underwater battlefields test the mettle of even the biggest and deadliest carnivores. All marine predators must overcome the sea's ever changing temperament, factor in its natural cycles … and for some, avoid becoming prey themselves.

Predators in the forest learn to use tree cover to their advantage.

In the places on Earth where fields of grass stretch as far as the eye can see, predators hide in plain sight. Cheetahs and secretary birds conquer extreme temperatures without trees to buffer the wind.

Predators adapt as they are confined by geography, changing conditions, or other species.
