Viewers follow the journey of several elephant seals, from their time on land during mating season to their deep dives into the ocean for food. The program showcases the seals’ incredible adaptations to life in both water and on land. Elephant seals are able to hold their breath for up to two hours and dive to depths of over a mile below the surface of the ocean. Scientists explain how they are able to do this and how their physiology has evolved to accommodate these impressive feats.

The episode also delves into the social dynamics of the elephant seal population. During breeding season, dominant males engage in intense battles for the right to mate with females. Viewers witness the brutal fights firsthand and learn about the importance of these battles for the survival of the species.
