Mammals that have adapted to live in cold waters—such as polar bears and whales—can stay warm largely because of their blubber, a thick layer of blubber. The blubber is evenly spread over much of their body, just as the shortening in this activity covered the surface of your finger in a thick layer.

How do cetaceans stay warm?
Whales use blubber as an insulation layer to help maintain the energy and warmth when they dive to cool depths or travel to cold waters such as in Alaska. The blubber layer is a thick (6 inches) layer of fat that is found under the skin.
How does blubber keep cetaceans warm?
To insulate the marine mammal, blood vessels in blubber constrict, or get smaller, in cold water. Constricted blood vessels reduce the flow of blood, thus reducing the energy required to heat the body. This conserves heat. Finally, blubber helps marine mammals stay buoyant, or float.
How do whales not freeze?
Whales, dolphins, seals and other marine mammals can generate their own heat and maintain a stable body temperature despite fluctuating environmental conditions. Like people, they are endothermic homeotherms—or more colloquially, "warm-blooded."
How do beluga whales stay warm in cold water?
Belugas live in these freezing waters all year round. ... To help them keep warm, Beluga whales have a thick layer of fat and connective tissue under their skin called blubber. This accounts for more than 40% of the Beluga whales' weight and is an excellent source of insulation.
How do leopard seals stay warm?
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.
How do sea lions keep warm?
Sea lions have unique adaptations that allow them to maintain their high body temperature while swimming around in icy water. The first of these is a thick blubber layer, which is approximately an inch thick. Covering that blubber is tightly packed fur. ... These layers help keep the body heat in.
How does fur keep animals warm?
"The denser and the longer the hairs are, the dryer or the more water-repellent the hairy surface is. Since the thermal conductivity of air is much smaller than that of water, trapping a layer of air in hairy surfaces reduces thermal conduction, which keeps animals warm in cold water," Nasto said.
How do animals keep warm in cold conditions?
Animals have a variety of different mechanisms to keep warm. Blubber (fat, like lard) and fur keep Arctic animals warm. Down feathers trap a layer of air next to the body to help keep birds warm. Materials that insulate to keep heat in or cold out are very important in everyday life to keep us healthy and comfortable.
How do lipids help polar bears stay warm?
Almost every aspect of the polar bears design is engineered for warmth. Their bodies are designed to be lined with a cozy layer of fat, which can be up to 3.4 inches thick. This fat not only helps polar bears keep warm, but acts as an energy store for slow hunting periods.
How do whales keep themselves warm?
Mammals that have adapted to live in cold waters—such as polar bears and whales—can stay warm largely because of their blubber, a thick layer of blubber. The blubber is evenly spread over much of their body, just as the shortening in this activity covered the surface of your finger in a thick layer.
How do whales stay warm for kids?
WHAT IS BLUBBER? Whales and Arctic mammals like penguins and polar bears, have a thick layer of fat under their skin called blubber. This fat can be anywhere from a couple of inches to a foot thick! The blubber keeps them warm and also stores nutrients their body can use when there isn't much food.
What helps the whale to protect itself in cold temperature?
Solution : A thick layer of fat in whales help them in protecting themselves in the cold weather.
Can belugas survive in warm water?
In the summer many populations are found in warm-water estuaries and river basins. Belugas seem to be well adapted to both a cold ocean habitat and a warmer freshwater habitat.
Why do Orcas live in cold water?
The reality is often quite different – the marine environment can be a surprisingly cold place. Water conducts heat far more effectively than air, which means that submerged animals quickly lose their body heat.
Can dolphins survive in cold water?
Whales and Dolphins can be found in almost every sea and ocean, from the Arctic ocean, through the tropics all the way to the Antarctic. Each species however has its own preferred type of habitat. Some live in cold water only, others in tropical oceans only.
