How do elephant seals survive? Elephant seals’ blubber accounts for much of their weight and is an adaptation to help them stay warm. The bigger an animal is, the less surface area (or skin exposed to the air) it has in relation to its volume, so it loses less heat.

Do elephant seals live in Antarctica? Southern elephant seals (Mirounga leonina) live in sub-Antarctic and Antarctic waters that feature brutally cold conditions but are rich in the fish, squid, and other marine foods these seals enjoy.
