How Do Elephant Seals Survive In Antarctica? Special adaptations
They can dive to over 1,500m and can stay submerged for up to 2 hours. Their red blood cells may, as an adaptation for diving, contain more haemoglobin than normal. These extra red blood cells make elephant seals’ blood very thick. Their muscles are also used to store oxygen.
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. Southern elephant seals breed on land but spend their winters in the frigid Antarctic waters near the Antarctic pack ice.
What adaptations do seals have to survive? Seals are marine mammals that have several adaptations for swimming and diving, including their body shape, flippers, and the dive response, which slows their heartbeat and directs more oxygen-rich blood to the heart, lungs, and brain.

What is Elephant adaptation?
Elephants have many adaptations that allow them to thrive in their warm habitats. Their big ears and wrinkly skin help them stay cool. Elephants also have long trunks that are used to grab food, suck up water, or throw dirt on their backs.
How does a seal resist the cold?
Seals have a thick layer of fat called blubber that helps them to trap warmth in their bodies. The blubber acts as a form of insulation to keep their internal body temperatures warm. Seal pups grow very quickly to build a thick blubber layer so that they can survive in the cold ocean waters.
What do elephant seals eat in Antarctica?
