Whales are warm blooded marine mammals that can tolerate cold water temperatures. 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 whales 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 maintain temperature?
Whales are warm-blooded marine mammals and as such they have certain internal metabolic processes that help them stay warm and help to stabilize their bodies temperature in cold environments. ... Whales are also able to keep warm due to the thick layer of insulated blubber that surrounds their body.
How do killer whales maintain body temperature?
Just under a killer whale's skin lies a thick layer of blubber, composed of fat cells and fibrous connective tissue. Blubber helps insulate a whale from heat loss. ... A killer whale's circulatory system helps maintain body temperature; it adjusts to conserve or dissipate body heat.
How does whales maintain homeostasis?
Whales have a 20 inch thick layer of blubber that protects them from extreme temperatures. Blubber is a highly specialized skin adaptation where fat cells are trapped in a mesh of collagen. ... Flippers also help in cooling the whale and maintaining homeostasis. As mammals, whales must come to the surface to breathe.
How does blubber help keep animals warm?
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.
What does whale blubber do?
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 does blubber maintain homeostasis?
The thick blubber layer not only keeps heat on the inside of the body, but the outermost skin layer is cooled to the same temperature of the surrounding water to further reduce heat loss via conduction.
What is a whale blubber?
Whale blubber is a thick layer of fat (vascularized adipose tissue) that surrounds a whale's body in order to keep its vital organs warm while in cold climates. Depending on the species the thickness of the blubber can vary dramatically from 1 inch up to 11 inches thick.
How do mammals maintain their body temperature?
Mammals generate heat mainly by keeping their metabolic rate high. ... Mammals conserve body heat with their hair or fur. It traps a layer of warm air next to the skin. Most mammals can make their hair stand up from the skin, so it becomes an even better insulator.
How do whales keep warm in cold waters?
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 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 do Antarctic whales reduce heat loss from their circulating blood?
For the whales, blood circulation to the dermal layer below appendage and body skin surfaces proved to be essential for sufficient heat dissipation. ... Heat loss can be reduced if the outermost tissue layers are allowed to cool. This is achieved by minimizing convective radial heat flow via the circulation.
What adaptations help the blue whale survive?
Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth ...
What helps whales survive?
When present, the dorsal fin is helpful for stability and has no support in the way of bones. Whales are able to survive in deep or freezing polar water because of a layer of fat, called blubber , covering their entire body underneath the skin. Blubber is much thicker than the fat found in other mammals.
Is whale blubber flammable?
“As the whale decomposes it releases gases such as methane and ammonia that build-up inside the body cavities. There's a real risk of an explosion, partly as a result of the build-up of pressure and also because these gases are flammable,” said Paul Jepson, a cetacean biologist at the Institute of Zoology in London.
