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. Regardless of temperature, depth, or terrain, each distinct marine habitat calls for different body designs, uniquely evolved senses, and outrageously complex - even bizarre - tactics for success. Director: Eleanor Grant (2013)
