Penguins often huddle together for various purposes, primarily for safety from predators. Additionally, in cold environments, huddling aids in preserving body heat, ensuring the birds stay warm in their frigid habitats.

Unlike most birds with hollow bones for flight, penguins evolved with solid bones to enhance their swimming abilities. This adaptation reduces buoyancy, aiding in their efficient navigation underwater.

In addition to their thick feathers, penguins rely on a special gland near the base of their tail to stay warm. They spend hours each day applying waterproof oil to their feathers, especially before swimming, ensuring effective insulation against the cold.

Despite their appearances in holiday cartoons, penguins and polar bears never coexist in the wild. Penguins inhabit the southern hemisphere, while polar bears reside in the northern hemisphere, with a clear geographic separation at the equator.

Penguin feet are marvellously adapted for both walking and swimming. Some species trek up to 60 miles across sea ice to reach their breeding grounds, while their feet also serve as effective rudders, aiding in steering and control while swimming.

Male penguins often present female penguins with rocks as tokens of affection, which the females then utilise to construct their nests.
