* Insulation: Blubber acts as a natural insulator, trapping heat and keeping the walrus warm in the icy waters of the Arctic. This is crucial for their survival in cold environments.
* Buoyancy: Blubber also helps walruses maintain their buoyancy in the water. It makes them more streamlined and reduces the energy required to swim.
* Energy Reserve: Blubber serves as a vital energy reserve. Walruses can rely on their blubber for sustenance during times when food is scarce, especially during the winter months when ice coverage makes hunting difficult.
* Protection: The thick layer of blubber also provides some protection from predators. It acts as a cushion against bites and stings.
In short, the layer of blubber is essential for walruses to thrive in their harsh Arctic habitat. It allows them to regulate their body temperature, swim efficiently, store energy, and defend themselves.
