Why do arctic animals have blubber?
The answer is blubber! Blubber is a thick layer of fat that lies underneath the skin of marine mammals such as seals, walruses and whales. Blubber is used to store energy, increase buoyancy, and insulate heat.
What is the use of blubber?
Blubber is important for most marine mammals, such as whales and seals. The thick layer of fat provides insulation from cold ocean temperatures. Blubber is also important because it stores energy that can be broken down to provide the animal energy when food is unavailable.

How animals stay warm using blubber?
In addition to providing insulation, blubber actually manipulates a mammal’s blood vessels to help it stay warm. Blubber is more densely packed with blood vessels than a typical layer of fat, and when the temperature drops, the blubber constricts those blood vessels to reduce the blood flow in the animal.
Why is thicker insulation advantageous to the survival of Arctic animals?
Blubber helps these marine mammals from getting too cold. (Cold-blooded marine animals, such as fish, sharks or crabs, do not need to stay warm and can let their body temperatures get closer to that of the water. Thus, they do not need to have this extra insulation.) That way, it helps to insulate an animal’s body.
What do animals need to survive in the Arctic?
Animals need to find ways to stay warm and to provide nourishment for themselves in order to survive the long, cold, winter months. Migration and hibernation are examples of behavioral adaptations used by animals in the Arctic tundra.
What do animals need to survive?

Groundhogs emerge as early as February, for example, whereas bats usually come out of hibernation in March.
What is hibernation for animals?
Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food. It involves physiological changes such as a drop in body temperature and slowed metabolism.
What animals are true hibernators?
Woodchucks, ground squirrels and bats are “true” hibernators. A woodchuck’s heart rate goes from 80 beats a minute when active to 4 or 5 beats a minute when in hibernation. Its body temperature drops from 98 degrees Fahrenheit to 38 degrees Fahrenheit.
