How Do Elephant Seals Adapt?

How Do Elephant Seals Adapt? 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.

What structure do elephant seals have that help them stay hydrated?

Nasal Turbinates. The amount of water elephant seals lose on land is controlled by the nasal turbinates and the counter-current heat exchange mechanism. This highly effective temporal counter-current exchange mechanism in their nasal passages minimizes the amount of water lost from their respiratory system.

How long can elephant seals hold their breath?
