Whale blubber. Blubber is a thick layer of vascularized adipose tissue under the skin of all cetaceans, pinnipeds, penguins, and sirenians. It was present in many marine reptiles, such as ichthyosaurs and plesiosaurs. [1]

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.

2023年10月19日 · Blubber is the thick layer of fat under the skin of marine mammals, such as seals, whales, and walruses. Most seals, like this one near McMurdo Sound, Antarctica, have blubber, a special kind of fat that can constitute up to half an animal's weight.

Whale oil is oil obtained from the blubber of whales. [1] Oil from the bowhead whale was sometimes known as train-oil , which comes from the Dutch word traan ("tear drop"). Sperm oil , a special kind of oil obtained from the head cavities of sperm whales , differs chemically from ordinary whale oil: it is composed mostly of liquid wax .

2018年8月29日 · All whales have a thick layer of blubber that keeps their body temperature regulated as they travel through cold water; at a high enough temperature this blubber can be rendered into oil. Sperm whales have an additional source of oil in a cavity in their head.

2025年1月17日 · 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 …

2011年12月29日 · 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.

2012年10月27日 · In order to reduce heat loss, whales have three main adaptations: reducing the body’s surface area to volume ratio, using their thick blubber layer as an insulator, and retaining heat through counter-current heat exchange.

Whale blubber, rich in fat and unique in composition, offers superior insulation compared to other marine animals. These adaptations help whales thrive in cold waters, showcasing nature's incredible ability to support life in diverse environments.

What is whale blubber and how is it typically prepared for consumption? Whale blubber is the thick layer of fat found under the skin of whales. It is a traditional food source in some cultures, particularly in Arctic regions.
