Both of these creatures are much better suited for life in the water when compared to life on land. Northern elephant seals fast during the mating season and can lose up to 36 percent of their body weight during this time. On the other hand, males can adopt a riskier strategy in the hopes of gaining as much mass as possible, and thus being able to have one extremely successful breeding season. [10] However, it makes navigating on land more difficult because they cannot turn their hind flippers forward to walk like the otariids.
