Learn English: The secret of chinstrap penguins' unique sleep habits (normal)

Chinstrap penguins have a fascinating way of getting their daily rest.

Instead of sleeping for long periods like most animals, they take lots of quick naps throughout the day.

These short naps, lasting just a few seconds, help them stay vigilant and protect their nests from predators.

Scientists believe this sleep pattern is a clever adaptation to the challenges of nesting and living in a busy penguin colony.
