What are sea lions adaptations?
Thick, oily fur and a layer of blubber enables sea lions to retain a high body temperature in frigid waters. A special process called thermoregulation also allows sea lions to keep warm. Thermoregulation occurs because the blood vessels on a sea lion’s flipper are exposed as they are not covered by blubber or fur.

How does the sea lion survive in its cold environment?
Sea lions have unique adaptations that allow them to maintain their high body temperature while swimming around in icy water.
