How do seals and sea lions stay warm in icy water?
Quick Answer
Many marine mammals use a thick layer of blubber to insulate their bodies. Some also reduce heat loss by controlling blood flow to their skin and flippers.
The Full Story
Seals and sea lions live in cold marine environments where heat loss is a major challenge. Blubber, a layer of fat under the skin, acts as insulation and energy storage. Their blood vessels can narrow in the skin and extremities to conserve core heat. Some species also have dense fur that adds insulation, especially when dry. These adaptations help them maintain body temperature in water that would quickly cool a land mammal.
