blubber etymology

Etymology:

The word "blubber" first appeared in the 16th century, deriving from the Middle English word "blober," which meant "a bubble" or "a swelling."

Meaning:

Blubber refers to a thick layer of fat under the skin of marine mammals, such as whales, seals, and walruses. It serves several vital functions, including:

  • Insulation: Blubber insulates the animal, reducing heat loss and allowing it to survive in cold water.
  • Buoyancy: Blubber helps the animal float, providing buoyancy and support in water.
  • Energy storage: Blubber stores excess energy and provides fuel during periods of food scarcity.

Origin:

Blubber is formed by a combination of fats and oils. When an animal consumes food in excess, the excess is stored as fat droplets in the blubber. Over time, these droplets merge to form a thick layer under the skin.

Functions:

In addition to its role in insulation, buoyancy, and energy storage, blubber also:

  • Protects the animal from blunt force trauma: The thick layer of blubber can absorb and dissipate impact forces, reducing injuries.
  • Provides a source of water: When blubber is metabolized, it produces water as a byproduct, which can be a valuable resource for marine mammals in arid environments.
  • Facilitates social bonding: In some species, blubber is used to establish social hierarchies and to strengthen bonds between individuals.
