My friends, have you ever thought about the animals that sleep deeply to survive the winter cold?
Some animals enter hibernation, a long period of sleep during which they reduce their activity. This helps protect their bodies from the extreme cold. Instead of constantly searching for food, they live off stored fat and conserve their energy.
Among these animals are:
• The bear: Sleeps all winter in its den.
• The hedgehog: Curls up and sleeps for long periods in winter.
• The turtle: Its body temperature drops, and it remains asleep in the mud or underground.
• The bat: Hides in caves and sleeps deeply to conserve energy.

Have you noticed how the fur color of some animals changes?
Take the Arctic rabbit, for example! Its fur turns completely white.
Why does this happen? The fur contains a natural pigment called melanin, which determines the color of fur, skin, or hair. In winter, animals produce less melanin, so their new fur grows white instead of brown or gray.
With this white fur, the animal becomes almost invisible in the snow… as if it’s wearing a magical cloak that hides it from predators!
