A body for swimming:The seal has a body perfectly adapted for life in the water. These seals swim so fast they can "jump" out of the sea onto the edge of the ice to get prey such as penguins. These cadence of calls are believed to be a part of a long range acoustic display for territorial purposes, or the attraction of a potential mate.[23]. Academic Press, 1981.

Adaptations for predatory feeding can be seen in the long curved canine teeth, in the lobed rear teeth used for filter feeding krill out of the water and in the massive size of the strong lower jaw with a large area towards the back where the powerful jaw muscles are attached.
