Here's why:
* They are adapted to aquatic life: Humpback whales have evolved to thrive in the ocean, with features like powerful tails for swimming, blubber for insulation, and blowholes for breathing air.
* Ocean provides natural shelter: The ocean itself offers protection from predators and harsh weather conditions.
* They migrate: Humpback whales undertake long migrations, traveling between their feeding and breeding grounds. This means they don't stay in one place long enough to build a shelter.
However, they do exhibit some behaviors that can be considered "shelter-like":
* Calves stay close to mothers: Humpback whale mothers provide constant care for their calves, keeping them close to their bodies for protection and warmth.
* They sometimes gather in groups: Whales might gather in groups for social reasons or for protection against predators, offering a sense of safety.
So, while humpback whales don't build shelters, they rely on the ocean's natural protection and their own behaviors to stay safe.
